My tutor has revised my English abstract and he wants me to ask the English speakers in the forum if the revised abstract can be read :-\ :-\ Line loss rate is an important parameter for quantifying grid transmission efficiency. Primary causes usually include leakage, partial discharge, and illegal use of electricity, among others. Such losses cause both financial harm to electric utilities and danger to users. The current abnormal line loss detection methods is power line carrier detection combined with manual detection. because the watt-hour meters are installed at a fixed and dispersive location, the power line communication method is inconvenience. The clock in the watt-hour meters is inaccurate, it causes large errors in the calculation of line loss rate. Manual detection faces the problems of high labor cost and low efficiency.To solve the problem of line loss monitoring and troubleshooting in low-voltage stations, an abnormal loss detection system for power grids based on IoT is designed. In this thesis, we designs five kinds of line loss detection devices for three kinds of power supply areas : 1.centralized area; 2.distributed area; 3.freestanding area.This system locates faults by modeling the power network as a tree topology, and measuring at each node the total input power, branch line output power, and user power. Considering the system's wide distribution and system price, the NB-IoT module is used for uploading data from each location. To ensure efficient transmission, the MQTT/HTTP protocol is used to communicate over the internet. An internet time service facilitates real-time synchronous monitoring, reducing calculation errors. By calculating the line loss rate of each node, the system can identify when and where the line loss exceeds usual or expected amount.This experiment proves that the system can make the current power industry line loss monitoring smarter, reducing the amount of work. |

Hello: What is the target audience and institutions or journals? IEEE? USA Universities? Firms to hire you? Your professor in China? What is the goal or objective of the paper? The issues of power TX and DIS mon are very different in USA or EU vs for instance China or 3rd world. For example the losses of thief of power are minor in the West but very bad in India. Finally line loss monitoring is very well developed and deployed in US and EU, so what exactly is the issue you are addressing? You need a T&D or power electrical engineer to review, not an informal EEVblog forum. Bon Chance, Jon |

One part I'm not sure about: "Because the watt-hour meters are installed at a fixed and dispersive location" You are saying they are dispersed too far apart right? "Considering the systems wide distribution and system price, the NB-IoT module is used for uploading data from each location." Not quite sure what is meant here |
