双馈感应电机新型直接转矩控制技术
A Novel Direct Torque Control Technique for Doubly-fed Induction Motor
摘要
Abstract
To facilitate the design of the direct torque controller for doubly fed induction moto(r DFIM),a space vector's mathematics model and equivalent circuit of the DFIM in the rotor coordinate were established,the expressions of the electromagnetic torque and rotor flux linkage were deduced. By analyzing the influence of rotor voltage space vector on rotor flux and electromagnetic torque,a novel direct torque control for DFIM was presented,which included two parts:the relative location of the rotor flux linkage and voltage was adjusted,and the combinational control way using two voltage vectors with 120°angle was used. Through many simulation results,the feasibility and effectiveness of the proposed control algorithm are verified.关键词
