摘要

风电在连接节点运行时，可能引起电压崩溃。电压稳定性的实时判别对风电并网具有重要意义。本文基于电力系统的等价性，构造了一个避免使用大量信息的电压稳定指标。风电连接节点的电压稳定性可通过采集节点电气信息的指标进行在线监测。该指标能够准确、及时地将负荷持续增加和暂态故障引起的风电连接节点电压崩溃和电压波动与仿真结果进行区分。

Research of Voltage Stability Online Index in Wind Grid-connected Power Generation Application

Voltage collapse could be caused by wind power operating at connecting node. Real time discrimination of voltage stability has significance for wind power connecting. In this paper, a voltage stability index which avoid using large number of information is structured based on equivalence of power system. The voltage stability of wind power connecting node can be online monitoring by the index with electrical information acquisition at the node. The index can exactly and timely distinguish the voltage collapse and voltage fluctuation in wind power connecting node which caused by sustained increasing of load and transient fault with simulation results.
