| 摘 要： | 广域测量系统对实时性要求严格，而通信延时是影响实时性的重要因素。通信延时作为广域测量系统延时的重要组成，带有不确定性，因此成为其通信性能研究的重点和难点。对广域测量系统的通信设备、通信业务和通信网络拓扑进行建模，并依此对电力系统稳态工况、故障工况和网络设备故障工况三类场景进行仿真。由此得到在不同工况下广域测量系统的通信延时大小，从而评估分析该系统的现状和瓶颈。为广域测量系统的研究分析提供了新方法，同时为其规划与建设提供了参考意见。

| Abstract: | Wide area measurement system (WAMS) is strict with real-time performance, and communication delay has great impact on real-time performance. Communication delay is an important part of WAMS delay. Its indeterminacy makes it important and difficult to study communication performance of WAMS. This paper establishes models of communication equipment, communication services and communication network topology of WAMS. According to these models, this paper gives three types of scene simulation, including static operating condition of power system, fault operating condition of power system and fault operating condition of network equipment. From this, the paper gets communication delay of WAMS in different operating condition to evaluate and analyze the current situation and bottleneck of WAMS. All above not only provide new method to research and analyze WAMS, but offer reference opinion to planning and construction of WAMS.
