摘要
提高变桨电机的稳态和动态控制性能,保证在不同风况及母线电压跌落的情况下维持电机高速运行的稳定性尤其重要。分析了内嵌式永磁同步电机的模型及约束条件,结合永磁同步电机的应用特点,基于SVPWM的矢量控制与电压外环的双电流弱磁控制策略,设计了矢量控制和弱磁控制系统模型并进行了仿真。基于该控制系统模型搭建了实验平台,对不同直流母线电压下矢量控制与弱磁控制的性能进行了对比测试和分析,验证了模型设计的合理性,实现了扩速性能。目前,该控制系统已应用于风机变桨伺服控制系统,具有较高应用价值。
It is important to improve the steady-state and dynamic control performance of the motor and ensure the stability of the motor running at high speed under different wind conditions and bus voltage drop.This paper analyzes the model and constraints condition of the interior permanent magnet synchronous motor(IPMSM),it combines with the application characteristics of the permanent magnet synchronous motor and bases on vector control of SVPWM and dual current flux-weakening control strategy of voltage outer loop,the vector control and flux-weakening control system model are designed and simulated.Then,the experimental platform is built based on the control system mode,and the performance of vector control and flux-weakening control under different DC bus voltages is tested and analyzed,it verifies the rationality of the model design and realizes the expansion performance.The control system has higher application value,and it has been used in the pitch servo control system of wind turbine.
