摘 要:提高變槳電機的穩(wěn)態(tài)和動態(tài)控制性能,保證在不同風況及母線電壓跌落的情況下維持電機高速運行的穩(wěn)定性尤其重要。分析了內(nèi)嵌式永磁同步電機的模型及約束條件,結(jié)合永磁同步電機的應用特點,基于 SVPWM 的矢量控制與電壓外環(huán)的雙電流弱磁控制策略,設計了矢量控制和弱磁控制系統(tǒng)模型并進行了仿真。基于該控制系統(tǒng)模型搭建了實驗平臺,對不同直流母線電壓下矢量控制與弱磁控制的性能進行了對比測試和分析,驗證了模型設計的合理性,實現(xiàn)了擴速性能。目前,該控制系統(tǒng)已應用于風機變槳伺服控制系統(tǒng),具有較高應用價值。

Abstract: 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.
Key words: interior permanent magnet synchronous motor; vector control ; flux-weakening control; voltage outer loop
