桂林变电站SVC与无功补偿装置协调运行

500kV桂林变电站直流融冰兼SVC装置（静止无功补偿装置）处于SVC运行模式时，能为系统提供快速的动态无功功率补偿，但在此模式时出现了220kV母线电压偏高、装置能耗偏高的现象。分析了SVC装置在补偿状态下的工作方式，以及如何与站内35kV侧的无功补偿设备协调运行，并在BPA仿真工具平台上进行了计算分析。结果表明，根据系统对补偿无功的要求合理地安排SVC和站内35kV补偿设备的运行方式，能有效降低站内主要设备的能耗。

The Coordinate Operation of the SVC and Reactive PowerL Compensation Device in Guilin Substation

The SVC/DC-deicer in 500 kV Guilin Substation can provide fast dynamic reactive power compensation to the power system when it is in SVC operation mode, but it was found in the meanwhile that the 220 kV bus-voltage was increased and thus the loss of equipments was increased. Analyzing the principle and characteristic of SVC operation, this paper discusses the coordinate operation of the SVC and reactive power compensation device at 35 kV bus side, and makes simulation analysis with BPA. The results show that it is necessary to choose reasonably the operation modes of the SVC and the device according to the reactive power compensation requirement of the system as to reduce the energy consumption of the main equipments in Guilin substation.
