基于人工补偿功率的功率因数监测方案及应用展望

Power Factor Monitoring Scheme and Application Prospect Based on Manual Compensation Power

针对地铁主变电所测得的计量功率因数无法正确反映供电局侧功率因数的问题,对现有地铁主变电所功率因数监测的现状进行分析,提出了一种基于人工补偿功率的功率因数监测方案,介绍了该方案的系统结构及关键设备,并通过测试验证了该方案的可靠性,最后对基于人工补偿功率的功率因数监测方案进行了总结和应用展望。

The metered power factor measured by the subway main substation cannot correctly reflect the power factor of the power supply bureau side.Aiming at this problem,the present situation of power factor monitoring in existing subway main substations is analyzed,and a power factor monitoring scheme based on artificially compensated power is proposed.The system structure and key equipment of the scheme are introduced,and the reliability of the scheme is verified by tests.Finally,a summary and application prospect of the power factor monitoring scheme based on artificially compensated power are given.
