Abstract

A fuzzy logic approach is applied to coordinate two control inputs: in phase voltage and quadrature voltage control of static synchronous series compensator (SSSC) to improve the transient stability of a SMIB system. The main aim of the paper is to analyze the effect of coordinated fuzzy logic based SSSC on real power flow, damping of first swing and to improve transient stability margin of a single machine infinite bus system. The two different controllers namely; [i] Conventional power oscillation damping controller of SSSC (NFLC), [ii] Fuzzy logic based coordinated controller of SSSC (CFLC) are considered for their comparative studies. Fuzzy rules for the controller are based on measurable components of the transmission line. Simulation results show that the proposed fuzzy logic based controller provides satisfactory performance in terms of increase in power transfer capability, improved damping of transients and transient stability margin of the test system. The performance of the controller is validated using advance software MATLAB.

基于模糊逻辑的静态同步串联补偿器(SSSC)的暂态稳定性改进

采用模糊逻辑方法对静态同步串联补偿器(SSSC)的相电压和正交电压控制两个控制输入进行协调，以提高SMIB系统的暂态稳定性。本文的主要目的是分析基于协调模糊逻辑的SSSC对单机无限母线系统实际潮流、首摆阻尼和提高暂态稳定裕度的影响。两个不同的控制器分别是;[1]对SSSC的传统功率振荡阻尼控制器(NFLC)和[2]基于模糊逻辑的SSSC协调控制器(CFLC)进行比较研究。控制器的模糊规则基于传输线的可测分量。仿真结果表明，所提出的基于模糊逻辑的控制器在提高功率传输能力、改善暂态阻尼和测试系统暂态稳定裕度方面具有令人满意的性能。利用MATLAB软件对控制器的性能进行了验证。
