摘　　要：在日益增长的配电网居民负荷中,以单相电动机为压缩机驱动的负荷占绝大多数。为此,提出了一种考虑单相电容运转电动机的负荷聚合方法,用一台等效电动机模拟多台电动机的动态特性。通过MATLAB/Simulink仿真软件,对聚合模型与多台电动机的动态特性进行了仿真对比,结果表明该方法可有效提高配电网中负荷的聚合精度,具有较高的准确性和适用性。In the growing household load in the distribution network,load driven by single-phase motor as the compressor is the majority.This paper presents a new method for load aggregation based on single-phase in-duction motor,in which an equivalent motor is used to simulate the dynamic characteristics of several motors.The dynamic characteristics of aggregation model and several motors are compared through MATLAB/Simulink.The simulation results show that the method can effectively improve simulation precision of load in distribution network,and is quite accurate and applicable.
