针对电网因风电接入引起输电阻塞、加剧系统振荡问题，提出以PID为基础的模糊PID励磁控制方法。首先，建立了同步发电机励磁控制系统数学模型。然后，对单机－无穷大系统进行MATLAB／Simulink仿真，将PID和PID＋PSS仿真结果进行对比，同时空载时，将常规PID和模糊PID仿真结果对比分析，得出结论：使用模糊PID进行励磁控制风电接入引起的问题明显改善，系统静态和暂态运行性能得到了显著提高，验证了模糊PID控制的可行性和准确性。

A Fuzzy-PID excitation control method based on PID was presented here ,in order to solve the transmission congestion problems and system oscillation caused by wind power integration .At first ,the mathematical model of syn-chronous generator excitation control system was built to simulate the single-infinite system by MATLAB/Simulink mod-ule .And then the results of PID and PID+PSS simulation were compared ,as well as the results of conventional PID and Fuzzy -PID simulation under the condition of no loading .The analysis indicates that the application of Fuzzy-PID exci-tation control has greatly improved the problems caused by wind power integration ,and the static and transient operation performance of the system has been significantly enhanced .This satisfying result verifies that Fuzzy -PID control is accu-rate and feasibile .
