摘要
以电机系统为研究对象，建立电机系统模型，基于MATLAB软件，理论模拟了电流特性、电源质量和负载率等对电机系统效率等指标的影响；并基于层次分析法给出了不同影响因素的权重比例。结果表明：电源质量对电机系统效率影响较大，对于一般运行负载率为0．6～1．0的电机，应尽量注意避免在过低的电源电压下运行；对于短时工作制或包含起动、制动等过程工作制的电机系统就应选用高起动转矩的电机。该结果为电机系统的节能诊断与潜力分析提供了一种新思路，具有指导意义。
Based on the model of motor system, the effect of current characteristics, power quality and load ration on motor energy consumption were studied. The results showed that the motor systems of different optimized parameters were of different weighting factor based on analytic hierarchy process method. Power quality had an crucial effect on the motor efficiency. Pump frequency conversion technologies were the main energy efficiency measurements for motor system. The results provided an evaluation method for the motor system construction.
