摘要
分析了现有石化企业电力系统中电源快速切换的现状和存在的问题,研发出一种自适应快速电源切换方案。该方案基于故障电流分析,可自适应不同运行方式和故障类型,极大提高了石化企业的供电可靠性。通过MATLAB仿真系统,对自适应快速电源切换方案进行了试验验证。目前,采用该切换方案的保护和快切装置已在现场得到成功应用并稳定运行至今。
With the shortage of the high speed transfer normal method in petrochemical enterprise supply network,a new adaptive high speed transfer plan was developed.This plan is based on fault current analysis,and it is suitable for different operating modes and fault type,so the reliability of petrochemical enterprise power supply is improved greatly.The adaptive high speed transfer plan is verified by the simulation system of MATLAB,and the plan has been successfully applied in the petrochemical enterprise supply network.
