A medium Voltage Line loss Control method based on Distribution Monitoring system

Under the background of Smart Grid Construction in China, the advanced power distribution monitoring system improves the measurement and control ability of the power grid company to the medium voltage power grid. Based on the distribution monitoring system and its monitoring data, a method to control the medium voltage line loss is presented. This method uses the running data and network parameters to calculate the line loss rate, finds the abnormal line loss in time, and constantly calculates the sensitivity of the line loss rate to each load node, and reduces the line loss rate by putting in the high sensitivity low voltage capacitance. The basic principle of the method is described, and the corresponding hardware and software design and calculation examples are given. According to the research results of this paper, the line loss of each medium voltage feeder can be monitored and controlled by the grid company. It is worth pointing out that this is the first time that the line loss can be controlled by long-distance capacitor switching in engineering.
