摘要
针对风电变桨永磁系统,分析了PHFVI法的基本原理并建立仿真模型,在PHFVI方法的原有框架下对滤波器等进行改进,分析导致误差的因素,针对性的提出改进措施,对转子转速和转子位置的观测误差进行削弱,进而提高系统的动态性能,通过仿真对比分析,验证了方案可行性。
Aiming at wind power variable-paddle permanent-magnet system,this paper analyzes the basic principle of PHFVI method and establishes a simulation model.Under the original framework of PHFVI method,the filter is improved,the factors causing errors are analyzed,and the improvement measures are targeted to propose.The observation errors of rotor speed and rotor position are weakened to improve dynamic performance of the system.Through simulation and comparison analyses,it is verified that the scheme is feasible.
