摘    要:为了减小用电设备对电网的谐波污染和提高自身的功率因数,PWM整流器的应用越来越广泛。文中根据PWM整流器在两相同步旋转坐标系下的数学模型,运用矢量控制的思想,实现了有功和无功的解耦控制。试验结果表明,控制方法具有响应速度快,稳态性能好,整流器接近单位功率因数运行,可显著抑制谐波对电网的干扰,改善电网运行品质,节约能源。

关 键 词:PWM整流  数学模型  矢量控制

Abstract:In order to reduce power system harmonic pollution and improve power factor, PWM rectifier application is becoming more and more wide. In this paper, based on the mathematical model of PWM rectifier under two phase synchronism revolving coordinate system , active and the idle work decoupling control has realized by utilizing vector control thought. The test results indicat that the control method has quick response speed and good static performance. It can obviously suppress the harmonic disturbance to electrical network, improve the movement quality of electrical network and save energy.
Keywords:PWM rectification  mathematical model  vector control
