摘　　要：鉴于现有的同步相量测量单元(PMU)对象模型无法满足其需要计算频率变化率等测量值,无法提供可路由的安全通信协议,介绍了IEC 61850-90-5基本概念,并在分析IEC 61850-90-5和IEEE C37.118两者异同的基础上,提出了基于IEC 61850-90-5的PMU信息模型,着重研究了按照IEC 61850-90-5的要求应用于同步相量交换的通信服务,并配置了新的传输和控制块,改进了现有的PMU对象模型,提高了IEEE C37.118信息IEC 61850-90-5转变的能力,更好地表现了同步相量,并为PMU同主站之间建立统一通信模型打下了理论基础。The existing object model of PMU cannot meet the requirement of computing the frequency variation or provide safe routable communication protocol. So in this paper, a PMU information model based on IEC 61850-90-5 is proposed after analyzing the similarities and differences between IEC 61850-90-5 and IEEE C37.118. The communication service used for synchronous phasor exchange is studied according to 90-5 protocol. And new transmission and control blocks are configured to improve the existing PMU object model. As a result, this method improves transforming ability from IEEE C37.118 to IEC61850-90-5, and achieves better performance of synchronous measurement. It also lays the theoretical foundations for establishing a unified communication model between PMU and master station.
