Abstract The proportional-integral (PI) control is widely used in permanent magnet synchronous generator wind generation system based on current source converter (CSC-PMSG-WGS). The traditional PI parameter design methods have issues such as low accuracy caused by approximate calculation or low generality caused by intelligent optimization algorithms for searching optimal PI parameters. To design proper PI parameters for the system with comprehensive considerations of reliability and simplicity, a general method based on the analytical method is proposed in this paper. Firstly, the transfer functions of system are analyzed considering the practical system specifications and the analytical formulas of PI parameters are derived from the transfer functions. Secondly, according to the control performance requirements and parameters of the CSC-PMSG-WGS, the key parameters in the formulas are determined, thus the final PI parameters are acquired. Finally, a 10 kW system is taken as an example, and the design process of PI parameters by the proposed method is presented in detail. The proposed method is verified by simulation in Matlab/Simulink and experimental results, which shows that the design of PI parameters for the controller of CSC-PMSG-WGS could be significantly simplified with expected transient and steady state control performances.
