Aiming at the problem of insufficient testing and verification of mining new-energy electric drive equipment under typical working conditions such as full-load start, ramp traction, load mutation and long downhill braking, an electric control system for a mining new-energy dynamometer was designed based on PLC and host computer collaborative control. The system realizes the functions of constant-speed operation, low-speed high-torque loading, load mutation simulation, VF separation and segmented control, braking reverse drag, and fault interlocking protection. Bench tests were carried out with motors of different power ratings, and field application verification was conducted in combination with a new-energy auxiliary transport equipment at a metal mine. The results show that when the system is in constant-speed operation, the steady-state speed error is within 0.44% and the speed fluctuation is within 2.11%. When the system is under low-speed high-torque loading, the deviation between the actual average torque and the set value is within 2.22%, and the torque fluctuation is within 6.7%. Under load mutation conditions, the maximum speed of the system is reduced to 8.6%, and under braking reverse drag conditions, the peak bus voltage is lower than the protection threshold. The protection tests for emergency stop, overspeed and overload achieved an accuracy rate of 100%, with a average emergency stop response time of 0.12 s. The engineering application results show that the system provides a new means for factory inspection, maintenance review, and operational diagnosis of new-energy electric drive systems for mines.

针对矿用新能源电驱装备在满载起步、坡道牵引、负载突变和长下坡制动等典型工况下测试验证不足的问题，基于PLC与上位机协同控制，设计了一套矿用新能源测功机电控系统。该系统可实现恒速运行、低速大转矩加载、负载突变模拟、VF分离分段控制、制动反拖及故障联锁保护等功能。以不同功率电机为对象开展台架试验，并结合某金属矿山新能源辅助运输装备进行现场应用验证。结果表明：系统恒速运行时，转速稳态误差在0.44%以内，转速波动在2.11%以内；系统低速大转矩加载时，实际平均转矩与设定值偏差在2.22%以内，转矩波动在6.7%以内；负载突变工况下，系统最大转速降低为8.6%，制动反拖工况下，母线电压峰值低于保护阈值；急停、超速、过载等保护测试准确率达到100%，急停平均响应时间为0.12 s。工程应用结果表明，该系统可为矿用新能源电驱系统出厂检验、检修复核和运维诊断提供了一种新的手段。
