【摘要】：针对传统矿用电机车驱动系统存在故障率高、消耗能量大、效率低等缺点以及机械编码器的使用会降低控制系统的可靠性和耐用性,提出了一种无速度传感器控制方法高频脉动电压信号注入法,并设计了一种基于无速度传感器控制的矿用电机车变频驱动系统。文章从控制原理、控制策略、系统拓扑结构以及软硬件设计等方面,给出了较详细的论述。通过系统理论分析、仿真建模与仿真结果分析,制作了矿用电机车变频驱动装置样机。样机经过在实验室数据测试、分析和现场试运行结果表明,所提出的控制方案具有较高的可行性和有效性,而且装置的维护工作量明显减小、可靠性满足煤矿恶劣环境的要求。
[Abstract]:In view of the disadvantages of the traditional mine electric locomotive drive system such as high failure rate, high energy consumption and low efficiency, and the use of mechanical encoder, the reliability and durability of the control system will be reduced.This paper presents a speed sensorless control method for high frequency pulsating voltage signal injection and designs a frequency conversion drive system for mine electric locomotives based on speed sensorless control.In this paper, the control principle, control strategy, system topology and hardware and software design are discussed in detail.Based on the system theory analysis, simulation modeling and simulation result analysis, the prototype of frequency conversion drive device of mine electric locomotive is made.The results of data test, analysis and field operation show that the proposed control scheme is more feasible and effective, and the maintenance workload of the device is obviously reduced, and the reliability meets the requirements of the harsh environment in coal mines.
