Analysis and Mitigation of Current Fluctuations in Synchronous Motors Caused by Starting Impacts of Asynchronous Motors

摘要

工业企业供配电系统中，异步电机与同步电机常共网运行，异步电机启动引发的无功冲击，易造成同母线同步机运行参数异常，威胁设备运行与生产安全^[1]。本文以某化工企业老区供配电系统为研究对象，针对2024年6月1日3#2000kW异步电机启动时，同母线2#同步空压机定子电流大幅波动的异常现象，深入剖析异步电机启动冲击成因及同步机恒功率因数控制的电流波动机理。通过案例对比、理论分析与数据验证，明确波动根源与优化效果，结合同步机实际运行参数提出专项抑制措施，可为工业共网电机系统的稳定优化提供实践参考与技术支撑。

Abstract

In industrial power supply and distribution systems, asynchronous motors and synchronous motors often operate on the same grid. The reactive power surge caused by asynchronous motor startup can easily lead to abnormal operating parameters of the synchronous motor connected to the common busbar, posing risks to equipment performance and production safety. Through case comparison, theoretical analysis, and data validation, the root causes of these fluctuations and optimization measures were identified. providing practical references and technical support for stabilizing and optimizing motor systems in industrial shared grids.
