| 摘 要： | 总结了协调二级电压控制(CSVC)的基本思想,提出了一种新的CSVC模型。在优先考虑中 枢母线电压偏差最小的前提下,利用多余的控制自由度保证本区域发电机运行在无功裕度更大、出 力更均衡的状态。仿真结果显示在分级电压控制体系中,如果二级控制环节采用所提出的CSVC 模型将有利于提高系统的电压稳定裕度。基于该CSVC模型的二级电压控制模块已经在国内某 省级电网得到实际应用。

| Abstract: | The basic idea of CSVC (coordinated secondary voltage control) is surveyed firstly and a novel CSVC model is presented. The first goal of this model is binding the voltages of the pilot nodes to the reference values, and the second goal with lower priority is the optimal management of the reactive power among the control generators, which means an operation status with larger VAR reserves and uniform distribution. Simulation results confirm the improvement of voltage stability margin with the CSVC model proposed. Based on this CSVC model, a secondary voltage control system is developed and implemented in a provincial electric power control center in China. |
