PSS放大倍数对电网小干扰计算影响分析
摘要
基于单机实测的PSS现场整定参数对于机组的本机振荡模式能取得较好抑制效果
但单机实测确定的PSS参数对于电网存在的区域间振荡模式
适应性较差。本文以PSS整定实测结果为依据
结合小干扰稳定分析
对于PSS参数优化方法进行了探索
并以实际电网进行了计算
结果表明
调整PSS增益可以有效改善系统的动态稳定水平。
Abstract
The PSS parameter setting based on single machine measurement can effectively restrain local-machine oscillation mode
except for inter area oscillation mode. This paper discussed the PSS parameter optimization method basing on experiment data and small signal analysis
and verified on actual system. The result indicated that adjusting PSS gain can effectively improve system dynamic stability.
