摘要:

在我国电网智能化建设背景下，先进的配电监测系统提高了电网公司对中压电网的测量与控制能力。利用配电监测系统及其监测数据，提出一种管控中压线损的方法。该方法利用运行数据及网络参数计算线损率，及时发现线损异常，并不断计算线损率对各个负荷节点的灵敏度，通过投入灵敏度较大低压电容来降低线损率。阐述了该方法的基本原理，给出了相应的硬件软件设计和计算实例。利用该研究结果，电网公司可以对每一条中压馈线的线损进行监测和控制，值得指出的是，这是首次在工程上实现了通过远程电容投切控制线损。

Abstract:

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.
