摘要
基于双馈感应发电机(DFIG)3阶机电模型研究了功率解耦控制,以3个方程的形式完整地设计了功率控制器,在保证有功、无功控制效果的前提下大大简化了控制器结构,使其易于在各种编程环境下实现,便于在国内大型电力系统分析软件中进行DFIG模型的开发。在MATLAB环境下实现了DFIG及其控制器的完整模型,并与MATLAB/Simulink自有模型进行仿真对比,验证了其正确性和可行性。最后验证了所提出的模型在系统级仿真分析中的实用性。
Based on the 3rd-order mech-electrical equation of DFIG, a decoupled power controller with three simplified equations is presented. The controller is simple and easy to be implemented in various programming environments while still retains high control performances on the active and reactive power. The controller is modeled with MATLAB and validated in comparison with the examples in MATLAB/Simulink. The feasibility of the proposed model in system-level simulation analysis is verified.
