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。

Abstract: Abstract: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.
