基于逆系统方法的双馈风力发电系统内模控制
Internal Model Control of Doubly Fed Induction Generators Based on Inverse System Method
摘要
Abstract
In allusion to the defects of unsatisfactory dynamic performance and weak anti-interference ability existing in approximate linearization-based separation control method being adopted in doubly-fed wind power generation system, from the viewpoints of power electronic device and electrical motor system integration a unified model of doubly-fed wind power generation system is built and by use of the principle of inverse system the doubly-fed wind power generation system is accurately linearized and synthesized by internal model control (IMC) theory, and then an inverse system internal model control strategy for doubly-fed wind power generation system is proposed to implement nonlinear decoupling control of doubly-fed wind power generation system. Simulation results show that the proposed control strategy not only can enhance the robustness of control system,but also improve response speed of doubly-fed wind power generation system, thus the proposed control strategy makes doubly-fed wind power generation system possessing satisfactory steady state behavior and dynamic performance.关键词
