通过对考虑配电网络的感应电动机聚合方法进行理论研究,提出了一种新的感应电动机聚合方法:根据感应电动机的空载和转予堵转2种状态计算聚合感应电动机电气参数。根据配电变压器和配电线路消耗功率计算配电网系统电抗。通过对湖南长沙榔梨220kV变电站所供配电网络的等值分析。表明该方法是有效的、可行的。
The theory about aggregation of induction motor loads connected to different bus bars in distribution network is studied in this paper. A new method for aggregating induction motor loads is presented. The values of the equivalent circuit parameters of the aggregate induction motor are determined by the two operating conditions, i.e., no-load and locked-rotor conditions. The effectiveness and feasibility of the proposed method is verified with the simulation results of the distribution network in the Changsha grid.
