摘要
针对矿用高压潜水泵电机在启动过程中存在的过电流问题,本文提出采用模糊自适应PID控制可变电抗器的高压电机软启动控制策略。本系统的核心采用高性能电机控制芯片TMS320F2812,配合电压检测、电流检测等外围电路,实现了高压电机的电流闭环控制。仿真结果证明,与传统电抗器限流软启动相比,该软启动器能使电机在启动初始阶段更加有效地降低启动电流的冲击,使电机平稳启动。
For the problem of shock and over current and voltage sage of mine high-voltage submersible motor in the process of start.Studying a soft start based on fuzzy adaptive PID control mode of high voltage asynchronous motor with variable reactor.The core of this system adopts high performance motor control chip TMS320F2812, cooperate to detect voltage, current and other peripheral circuit, realizes the high voltage motor current closed loop current limit control, and the hardware structure is given.The simulation results show that compared with the traditional reactor current limiting soft start, the motor in the initial stage can be more effective in reducing the impact of the starting current and also make motor start smoothly.
