摘　　要：我国海上油田局域电网正大规模接入陆地电网,受平台投产年限和成本因素影响,配套的电能计量设备参差不齐,导致电能计量结果存在一定的误差,这主要与计量设备本身性能及其外部电路结构有很大关系,是影响电能计量设备准确度的关键因素。本文重点分析了海上平台电网关口电能计量设备受二次回路压降影响的情况,制定有效的改进措施,为海上电力系统配置的不同的电能计量设备提升计量准确度提供了相应的解决方案。The local power grid of offshore oil fields in our country is being connected to the land power grid on a large scale.Due to the influence of platform operation years and cost factors,the supporting electric energy metering equipment is uneven,resulting in certain errors in electric energy metering results.This is mainly related to the performance of the metering equipment itself and its external circuit structure,which is a key factor affecting the accuracy of electric energy metering equipment.This article focuses on the analysis of the impact of secondary circuit voltage drop on the energy metering equipment at the gateway of offshore platform power grids,and formulates effective improvement measures to provide corresponding solutions for improving the measurement accuracy of different energy metering equipment configured in offshore power systems.
