摘要

针对独立自励异步发电机（SEIG）加负载等原因会导致其端电压跌落的特点,本文研究一种采用参数自适应模糊PI控制策略的静止同步补偿器（STATCOM）用于补偿机端电压,以提高SEIG的带载能力和电压调节能力。本文分别分析了SEIG和STATCOM的时域模型,并指出传统的PI控制较难满足机端电压暂态调节性能和控制系统自适应能力的要求,针对传统PI调节器的缺点,引入了参数自适应模糊PI（Fuzzy PI）控制策略。对该系统进行Matlab/Simulink仿真,结果表明本文提出的控制策略可对机端电压进行连续调节,具有较好的静、动态性能和鲁棒性。

Abstract：

For the self-excited asynchronous generator (SEIG) to increase load and other reasons will lead to the characteristics of the end voltage drop, this paper studies a parameter adaptive fuzzy PI control static synchronous compensator (STATCOM) used to compensate for the terminal voltage, To increase SEIG's load capacity and voltage regulation capabilities. The time domain models of SEIG and STATCOM are analyzed, and it is pointed out that the traditional PI control is difficult to meet the requirements of the terminal voltage transient regulation performance and the control system self-adaptive ability. For the shortcomings of the traditional PI regulator, the parameters introduced in this paper are self-adaptive. Fuzzy PI control strategy. The Matlab/Simulink simulation of the system shows that the control strategy proposed in this paper can continuously adjust the terminal voltage and has good static and dynamic performance and robustness.
