基于三电平转差矢量控制的矿用高压变频器研究
|
摘要
针对煤矿井下运输设备启动冲击大,运行效率低,电能浪费严重,设计了一种基于三电平转差矢量控制的矿用高压变频器,采用十二脉波整流电路和二极管箝位式逆变电路,并以载波同相层叠调制逆变电压波形,选择基于转差频率的矢量控制方案。通过搭建高压电机变频调速Simulink系统模型,对电机的调速性能进行分析。结果表明,电机可以迅速响应负载变化,并达到稳定状态,系统具有较高鲁棒性。
Aiming at the large impact of coal mine underground transportation equipment,low operating efficiency and serious waste of power,this paper designs a mine high-voltage inverter based on three-level slip vector control. The inverter adopts 12-pulse rectification circuit and diode clamped inverter circuit. The inverter voltage waveform is modulated by the carrier in-phase stacking,and the vector control scheme based on the slip frequency is selected. The speed control performance of the motor is analyzed by constructing the Simulink system model of high-voltage motor variable frequency speed regulation. The results show that the motor can respond quickly to load changes and reach a stable state,and the system has high robustness.
