摘要
为了改善传统直接功率控制系统的性能和可靠性,采用虚拟磁链定向的方法来实现功率估算。在Matlab/Simulink环境下,通过搭建了基于虚拟磁链的18扇区开关表仿真模型,并与传统的电压定向开关表控制进行比较。仿真结果表明:基于虚拟磁链的控制系统具有良好的动静态特性,系统可靠性较好,能有效抑制整流器对电网的谐波干扰。
In order to improve the performance and reliability of the direct power control system,virtual flux（VF） oriented approach to estimate the power was used.In Matlab/Simulink environment, a 18-sectors switch table control system- simulation model was built based on virtual flux （VF）, with the traditional switch table is compared. Simulation results show that the DPC system based on VF has good static, dynamic performance and system reliability,which can effectively inhibit the rectifier harmonic interference on the power grid.
