摘　　要：配电网电能计量装置具有数量多、涉及面广、影响大等特点,其良好的整体计量性能对保证电能贸易结算的公平公正具有重要意义。如何优化配电网电能计量装置的整体误差是计量领域的难题,这里提出了通过改变互感器二次负荷的方式实现配电网电能计量装置整体误差的优化方法,并应用该方法开展优化试验,实现了对电能计量装置整体误差的优化,为提高电能计量装置的计量准确性提供有意义的参考。There are numerous electric energy metering devices which involve in many aspects running in distribution network, and the accuracy of their integral error has a significant influence on keeping the equity and justness of electric energy trade. However, how to minimize the integral error of electric energy metering devices is a big issue in measurement domain. A meth-od by changing the secondary load of transformers to optimize the integral error of metering devices is proposed, and optimiza-tion tests are carried out using this method. It is confirmed that the integral error of electric energy metering devices can be op-timized with this method, which provides a useful reference for improving the accuracy of metering devices.
