摘要
本文建立了UPFC的动态数学模型,提出了UPFC的模糊控制策略。并对UPFC的四个调节器分别设计了控制器。文中对UPFC的阻尼控制器进行了改进,给出了运用带多个因子的模糊规则自调整的模糊控制器。并运用MATLAB的仿真工具,对含UPFC的双机系统进行了仿真。仿真结果表明,UPFC采用模糊控制后不但能有效地调节线路潮流,而且能有效地抑制振荡,提高电力系统的暂态稳定性。
UPFC mathematic model is built up and the fuzzy control strategy of UPFC is proposed. To four controlling variables, this paper also respectively designs four controllers . Furthermore, the damping controller is improved by means of applying fuzzy control rule to it . Finally, the 2-generator with UPFC is simulated by MATLAB tools. As a result, UPFC with fuzzy controller can effectively adjust real and reactive power of transmission and damp oscillation during transient conditions.
