文章通过对机车动力控制方式,交流电机的特性,及电机工作参数控制的方法,对机车牵引变流器的原理、结构、控制进行了细致的分析和论述。机车的控制是通过动态调整交流牵引电机实际工作点,以适应机车牵引特性的要求,四象限整流器调节的是输入电压与电网电压的相位关系,牵引逆变器调节的是输出电压与交流牵引电机转速的匹配关系,调节的主线是保持能量传输的动态平衡。使机车性能控制满足重载牵引运输的需要,并最大限度地利用了电网的牵引供电能力。
Through the control of locomotive power, the characteristics of AC motor and the control method of motor operating parameters, the principle, structure and control of locomotive traction converter are analyzed and discussed in detail. Locomotive control is through the dynamic adjustment of AC traction motor actual operating point to meet locomotive traction characteristics of the requirements of four-quadrant rectifier is the input voltage and the phase voltage of the grid voltage, traction inverter regulation is the output voltage and AC traction motor Speed matching, the main line of regulation is to maintain the dynamic balance of energy transmission. So that locomotive performance control to meet the needs of heavy haulage and transport, and to maximize the use of the grid traction power supply capacity.
