影响变电站电能计量准确度的原因分析及解决措施

Analysis and Solutions of Energy Measurement Accuracy Rating in Substation

变电站的电量计量的准确度对计算变电站网络损耗起着重要作用。基于变电站实际运行中存在的问题,从电量计量系统的组成部分出发,分析了电流互感器、电压互感器、二次回路、计量表等部分对电能计量系统准确度的影响,并提出改善措施,为变电站的安全、稳定、经济运行提供了理论基础。

Power measurement accuracy of substation plays an important role in the calculation of substation network loss.Based on the problems existing in the actual operation of substation, embarked from the part of the electricity metering system, the current transformer, the voltage transformer, the secondary loop, the meter, etc, were analysed. Improvement measures were put forward, these provides a theoretical basis to the safe, stable and economic operation of transformer substation.
