基于虚拟同步电动机技术的变频器控制策略研究
A Novel Frequency-converter Control Strategy Based on Virtual Synchronous Motors
摘要
Abstract
Primary frequency regulation is effective means to protect the stability of power system.Frequency converter occupies a large proportion in production and daily life,in order to produce beneficial effects to the primary frequency regulation of the power system,a control strategy based on the technology of virtual synchronous motor (VSM) was proposed.The rectifier and the inverter are two main parts of the frequency converter.For the rectifier part,Udc-Q control strategy was utilized,it can control the converter's reactive power output to power grid,and effectively decrease the converter's harmonics output to power grid.For the inverter part,VSM control strategy was used,it concluded power-frequency controller and excitation controller,and it could change the inverter's output voltage and frequency with the change of motor load,and could adjust the inverter's output active power with the change of system frequency.The frequency converter control strategy based on VSM was simulated by using Simulink/Matlab.The simulation results show that the proposed control strategy can follow the mechanical inertia and electrical characteristics of the synchronous motor,and can effectively improve system power quality and system stability.关键词
