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.

Key words： self-excited induction generator static synchronous compensator (STATCOM) voltage control fuzzy PI
