摘要
阐述一种新型地铁地面供电电源——三相电压型PWM整流装置的数学模型及其控制方法。通过试验验证控制方法的正确性和工程应用的可行性。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。
It is explained the mathematical model and control method of a new type of ground power supply for metro vehicles, the 3-phase voltage type of PWM rectifier. Through the tests and experiments, the correctness of the control method and the feasibility of engineering application is verified. Test results show that the control method features fast response and excellent reliability. The rectifier operates with a power factor close to unit, which could suppress dramatically the interferences to the power line by harmonics, improving the power line quality and saving energy.
