菲律宾Therma South热电厂输煤系统电动机启动压降分析

Analysis of motor start-up voltage drop for the coal handling system of Therma South Thermal Power Plant in Philippines

以菲律宾Therma South项目为基础,对电厂输煤系统设计-采购-施工(EPC)项目中常用低压笼型感应电动机的全压启动电压降进行了分析,并针对不同变压器容量和不同供电距离,给出了各电动机的启动数据,形成主流电动机启动速查计算数据,对项目设计中的电动机启动校验具有指导意义,工程实际应用效果显著。

Based on the Therma South Project in Philippines,this paper analyzed the full-voltage start-up voltage drop of low voltage squirrel-cage induction motor,which is commonly used in engineering procurement construction( EPC) project of coal handling system of power plant. And aiming at the different transformer capacities and power supply distances,this paper obtained the start-up data of motors and built the rapid calculation start-up data of mainstream motors,which has guiding significance for the motor start-up check in project design and has notable effect in engineering practical application.
