基于Fuzzy-PI的电力系统稳定器控制策略的实现

The realization of power System stabilizer control strategy based on Fuzzy-PI

改进的Fuzzy-PI控制策略,模糊控制单元为比例积分控制提供实时增益调节,模糊规则合成推理的改进提高了控制鲁棒性。二区域四机的仿真结果证明施加这种控制策略的电力系统稳定器抑制振荡能力更强,进入稳态时间更短。

In this fuzzy-PI control strategy, fuzzy control unit provides real-time scoring gains for Pl control, and strategy increases the robustness of the power system stabilizer with improved reasoning of synthetic ambiguous rules, Simulation results in two-area four-machine proves that power system stabilizer under this strategy has stronger capacity of checking shocks and becomes stable more quickly.
