It looks like the current sensors and voltage sensors are mixed up between lines? And all of the current clamps are put on backwards?

L1: U(Gray), I(-Red)
L2: U(Red), I(-Blue)
L3: U(Blue), I(-Gray)

Because of this, the total powers are wrong (for the uncorrected case on the left). There must be a significant amount of energy storage, probably nearly 1 power-line-cycle of the max power? Maybe around 10 mF of capacitance at 120VDC. However, it has to be able to take up the current very quickly during the peaks. The control loop can't know the future, so perhaps it is correcting the current draw to be balanced based on the power which had been drawn the previous cycle? If all goes wrong (runs out of energy, demand wasn't what was expected, etc), then it can just give up at a zero-crossing and reset its state machine.

This could go very wrong when equipment draws energy every other power line cycle. Don't some triac-based heaters do that? The other strategy would be to just have a couple power line cycles of energy, so that it could average it out over a few cycles, but there should always be some pathological case where the correction fails.

EDIT/POSTSCRIPT: While I believe that this overall technology is reasonable (excluding some bad descriptions of it) and good for some niche applications, it's likely much better to just balance your loads and migrate to power equipment which has less harmonics (replace VFDs, etc, with newer models). However, I've never worked in an industrial setting, so I don't know how the economics balance out.

It is funny to us because here we provide more data and analytics that they could ever receive from their equipment, but still they are not convinced until they see it with their own eyes on their own instruments.
I wonder why the voltage and current are so out of phase.

Yes that will be it, as usual 3DFS haven't a clue.

It could be simply the phase difference between voltage and current. What those graphs also show is that the load optimization increases the phase shifting. This is to be expected since the blue box needs time for measurements, calculation and power correction. And the capacitance and inductance of mains wiring and loads don't make the job easier. So any power correction will have a delayed impact. This also means the box doesn't provide much benefit for data centers. To increase power efficiency and to reduce bills for power a HV DC power distribution (incl. HV DC PSUs for servers and network elements) would make more sense.

Err, the whole point of a box doing power factor correction is to REDUCE the phase angle between the voltage and the current!

This is just a measurement screwup with placing the current clamps.

The real value in these sort of fairly small AHF boxes (But I like mine with actual data and salted with less gibberish) is when you are doing something like changing the use of an existing building and find you have neutral overload issues for example because of that whole floor of cheap ass PCs your accounts department put in. 

Much cheaper to knock off 40A or so of triplen with an AHF box then it is to pull bigger wire 8 floors up thru trunking that is too small!

Band aid, maybe, but it gets your site signed off.

I had an issue in a theatre (LOADS of phase angle dimming that changes moment by moment), the choices were an AHC box (Quite a big one at that) or a 315kVA K rated delta-star transformer that we had no space for.....

The (Real) AHC tech has a valid use case, it is the frantic fluffing by the marketing guy that is cracking me up.

But only to the requirement of the utility company of course... that requires a proof and a reason. The thing is that the power that is installed and paid for today includes all costs needed to run the system - with all its inefficiencies and a good amount of safety margin.
They do not make up a problem and sell you the solution. Apparent power and real power are one thing, sinusoidal current is another. And then there is wear and tear, but i don´t get how the shape in which the heat or vibration is produced would make that much of a difference or if it is the main cause for failures in the first place. Maybe there is no point in mitigating effects that do not preempt the first failure that typically occurs.

Then there is this: Why should a customer try to solve a problem that the utility does not recognize as such if the goal is to protect the grid and transformer and acutally prolongs its life. Wouldn´t that be in the interest of the utility and therefore fixed there? Utilities have plenty of data, plenty of customers and can see which loads cause which failures.

Maybe in fringe cases with island grids that operate too close to physical limits this plays a role, but there the supplier and load are usually under the same control and could be solved on the side of the load anyway. But you are usually not in a good situation when intentionally operating too close to physical limits, it is called bad design.

Which could be solved/mitigated in the first place by rearranging loads between phases. Cheapest way possible, just change clamps. But this technology is not about phase split, it is about a one-sided redefinition of what Power Quality Rating means.

Btw. there are some data protocols on the grid... like switching on street lights, nightly rate for electrical heaters. You do not want to compensate those.
Support your local planet.

Moving loads between phases does not help if the neutral current is mostly third harmonic however, because third harmonic sums in the neutral rather then cancelling.

This is what had me on that theatre install, full load at 30% on the dimmers and the RMS neutral current wound up to nearly 200% of the phase current.

Agreed, that you only fix as much as is economical, but in this case AHF was MUCH more cost effective then burning the triplen as heat in a delta-star transformer, mostly because we did not have a good location for the transformer.

The other interesting application is in sites where you have significant voltage harmonics AND static power factor correction cap banks (Which REALLY don't like voltage harmonics because they push up the current in the cap bank by a lot). AHC setup to reduce the voltage harmonics only can allow a significantly smaller current rating on the passive cap bank. Usually an issue out on the end of a long feed line where the supply impedance is not as low as it could be.

Now both are slightly niche applications, and there are usually cheaper ways to skin this, but the AHF tools have a place. 

Agreed that the marketing drivel is unusually severe with this one.

3DFS think their load current balancing S/W has something to do with controlling the frequency of the grid. :-DD

It has everything to do with it. Controlling the frequency using rotating machines is the the only way when the power is not controlled and balanced in real time.

To correct the unbalanced currents, 3DFS's magic software has to follow the phase and frequency of the grid - whatever it is, so the amount of control that 3DFS's magic software has on the frequency is less than zero. :D

Edit!  How would it even know if the 60Hz's phase should be moved slightly a head or behind what it currently is.

I don't think cdoerfler is claiming that 3DFS can actively control the frequency of the grid. Rather, he seems to state that 3DFS can avoid load fluctuations, to which the grid would otherwise need to respond by varying the frequency.

However, it is unclear to me whether that second claim is correct. Assuming that the 3DFS technology can only compensate for load imbalances between phases, how would that change the overall load the grid sees?

Frequency control is irrelevant when precision phase control is possible, which is what SDE delivers. Frequency for SDE can be software defined.

frequency response using batteries is 1. not real time and 2. limited by the energy within the battery.

FR using 3DFS tech is Real-Time, every microsecond, and unlimited because it is using the power from the grid to correct the power.

SDE has full phase control. Reactive power correction in 180 degrees. This is a much more important feature.

It cannot correct the entire grids frequency, but when fully distributed throughout the grid, frequency response will no longer be needed.

The grid frequency is controlled by the (im-)balance of the power fed into the grid and the power consumed by loads.

Bonkers!

"It cannot correct the entire grids frequency,"

But it can correct just part of the grid's frequency?  :-//  Or different parts of the grid will have a different frequency? :)
 
"but when fully distributed throughout the grid,"

Don't worry, it won't be!

"frequency response will no longer be needed."

I'm amazed (but not much!) that you think the changing phase and frequency of the grid is a fault. You seem to think large rotating machinery being unstable and having inertia is the problem, compared with electronics (24-bit over-sampled, sub-cycle, and in real time of course!).
It would be very easy to use atomic clocks to keep a rotating machine's frequency and phase exact for ever if we wanted, perhaps you could suggest the idea to the big electricky suppliers as yet another SDE innovation.

EMP Detection: Software-Defined Electricity operates on the principle of oversampling inputs to extract maximum information on the power flow to deliver the most possible time to react to any electrical event. EMP travels in waves. In oceans preceding a tsunami, shore water recedes significantly back before the inrush. A similar phenomenon is true with EMP in power networks. Time is the most precious resource related to EMP damage mitigation. The sooner it is detected, the more time there is to react.

I remember thinking about that at the time. A generator changes the phase/frequency by adding or removing energy/fuel, it's impossible to use a 3ph supply's own energy to change its frequency. :horse:

Alas for the EMP challenge we were unsuccessful. You are correct. They decided on the incredible innovation of shielding.  :palm:  Some people cannot see the elegance of this solution. Onward and upward.

Re: phase frequency, again you are incorrect. The device is temporarily storing the energy in the FESS which is then a separate source for instant injection. It is also where any extraction is temporarily stored. By temporarily storing the extracted energy and then using it when an injection is required, the device does not have to consume any "new power" from the grid/generator for the injections. This is part of what allows the device to be 98% efficient.

Compare that to the modern Cap banks which charge with grid power every single time. What an absurd waste of energy.

It's impossible for the phase/frequency in the wires to suddenly change as it passes the VectorQ2.

"This is part of what allows the device to be 98% efficient."

Your efficiencies hardly ever make any sense. If the VectorQ2 is doing many kWs of current correction it's efficiency should be well over 100%, if there's almost no current correcting to be done it's efficiency is less than zero, 98% doesn't come into it.

Agree. If the time-averaged efficiency is less than 100%, you would be better off not installing that thing, right?

Yes, :) it's only for high current, bad PF, unbalanced load, and charged for it, customers really, but they claimed to be developing one for the home. LOL.
In the video above somewhere, PQ somehow gets mixed with power used, charged for, and overall electrical efficiency, perhaps what's happening at the supplier's transformer is some of the 26 parameters. :)

This is mixing topics, the two must be separated; frequency regulation and phase angle control.

The Vector is making minute, in situ corrections with tiny amounts of current. It does not require massive amounts of current because it is maintaining the synchronization. Its like steering while driving, there are small corrections as you drive, not massive back and forth over steering (which would be the case using cap banks).

It is true that if the power is perfect coming in the facility, the box would lower its efficiency as it has to draw 70-120W at all times, but that is not reality. It is always correcting and balancing.

The calculation of efficiency is key here. We are using 70-120W of power at all times to correct (bring to full synchonization and balance) of 60kW at all times.

Don't forget surge protection, asset performance improvement and all of the data and analytics on each load.

The residential version is a trickier business case. Outside of high consumers of power or special cases like audiophiles, etc, the energy savings are just not there as homeowners usually have one or two major loads and are only in their house for 8-10 hours, mainly sleeping. It makes more sense from a utility perspective preventing the reactive power, phase imbalance and harmonics from affecting the load supply and capacity. Once we scale up and prices drop, the residential unit becomes more attractive.

If a home has solar and an EV, the case becomes very clear though as it improves the output of the solar and charging times and rates of the ev charger while protecting them both from poor power quality related wear and tear.

It's difficult the know where to start here, but I'll have a go. >:D

This is mixing topics, the two must be separated; frequency regulation and phase angle control.

 :wtf:

"The Vector is making minute, in situ corrections with tiny amounts of current."

It will be making (very roughly) around 20mA sized adjustments to about 3 Amps of current. 20mA is a tiny amount of current to a 3 ph supply, and nothing to do with micro Amps, the control signals will be higher than micro Amps. :)

"It does not require massive amounts of current because it is maintaining the synchronization."

It requires the larger current corrections approx. every 1/4 mains cycle, there's no such thing as "massive current now no longer required because it's maintaining the synchronization".

"Its like steering while driving, there are small corrections as you drive, not massive back and forth over steering (which would be the case using cap banks)."

No, It's more like peddling up a quite steep hill, you can't just stop peddling once you've got the bike moving up the hill.

"It is true that if the power is perfect coming in the facility,"

You probably mean, if the load(s) are already drawing their current in phase and balanced, which is a quite bit different.

"The calculation of efficiency is key here."

ROTFL

"We are using 70-120W of power at all times to correct (bring to full synchonization and balance) of 60kW at all times."

The 70-120W is just for the magic computing, the power control devices will use and dissipate more, especially if they're switching Amps at MHz frequencies. :)

"Don't forget surge protection,"

I haven't! It doesn't do very much in the way of surge protection, the wires are much to thin!

"asset performance improvement"

LOL  How do the assets even know if the current in the supplier's transformer is balanced or not.

"The residential version is a trickier business case. Outside of high consumers of power or special cases like audiophiles,"

Yeah, there's nothing there, even for audiophools.

"If a home has solar and an EV, the case becomes very clear though as it improves the output of the solar and charging times and rates of the ev charger"

You've mentioned the correction of the output power of solar and generators, for these devices does the VectorQ2 have to be connected backwards, think about it!

CML+  That took much longer than I thought it would.

It's difficult the know where to start here, but I'll have a go. >:D

This is mixing topics, the two must be separated; frequency regulation and phase angle control.

 :wtf:

"The Vector is making minute, in situ corrections with tiny amounts of current."

It will be making (very roughly) around 20mA sized adjustments to about 3 Amps of current. 20mA is a tiny amount of current to a 3 ph supply, and nothing to do with micro Amps, the control signals will be higher than micro Amps. :)

"It does not require massive amounts of current because it is maintaining the synchronization."

It requires the larger current corrections approx. every 1/4 mains cycle, there's no such thing as "massive current now no longer required because it's maintaining the synchronization".

"Its like steering while driving, there are small corrections as you drive, not massive back and forth over steering (which would be the case using cap banks)."

No, It's more like peddling up a quite steep hill, you can't just stop peddling once you've got the bike moving up the hill.

"It is true that if the power is perfect coming in the facility,"

You probably mean, if the load(s) are already drawing their current in phase and balanced, which is a quite bit different.

"The calculation of efficiency is key here."

ROTFL

"We are using 70-120W of power at all times to correct (bring to full synchonization and balance) of 60kW at all times."

The 70-120W is just for the magic computing, the power control devices will use and dissipate more, especially if they're switching Amps at MHz frequencies. :)

"Don't forget surge protection,"

I haven't! It doesn't do very much in the way of surge protection, the wires are much to thin!

"asset performance improvement"

I get that you are trolling, but you are not even bothering to try here.

The 70-120W INCLUDES the power electronics and the correction is bidirectional.

The asset performance improvement comes from ideal non-fluctuating power to every asset. The most illustrative example here is a motor. When the current and voltage are not aligned, a 4 pole motor alternates between motor and generator at each pole. This is the most significant source of motor destruction in the power network. When there are multiple motors in the same panel, they interact with each other in this harmful way resulting in wear and tear that shortens the life of the motors by years.

In addition, the motors droop, falling below the rated 1375 rpm when they are loaded. In reality this is a problem with power supply. When SDE is installed in a motor control center for example, all the motors operate at the rated rpm whether loaded or not and since the C&V are always aligned, the motors never experience the fluctuation from generator to motor.
