摘要

通信时延是广域测量系统(WAMS)应用于广域阻尼控制所需计及的重要因素

如何描述WAMS通信时延尚缺乏有效的模型

因而提出了基于概率模型的WAMS通信时延特性建模方法。在浙江电网WAMS实际运行工况下

根据WAMS数据包特点以及通信结构

对相量测量单元(PMU)子站到WAMS主站的总体通信时延进行了测定

分析了时延数据的统计特点

结果表明:各PMU子站通信时延均值都小于100 ms

多数PMU子站通信时延大于100 ms的数据占比小于1%。最后基于浙江电网WAMS大量实测数据对通信时延采用概率模型进行建模

表明对于不同时段

不同PMU子站

采用莱斯分布能够有效地表征WAMS通信时延的分布特性。

Abstract

Communication delay in the wide area measurement system (WAMS) is a not-to-be-neglected factor during controller design yet lacking an effective model for its description. A method based on a probabilistic model for describing the communication delay in WAMS is proposed. Under the actual operation condition of WAMS of Zhejiang Power Grid

the communication delay between phasor measurement units (PMUs) substation and the main station of WAMS is measured and the statistical characteristics of the delay are analyzed based on the characteristics of the data packets and structure of WAMS. It is shown that: the average communication delays of all substations are less than 100 ms; in most substations

the measured data that are over 100 ms accounts for less than 1% of the total measurements. Finally

a model of communication delay is built based on the probabilistic model and the large amount of actual operation data measured in the WAMS of Zhenjiang Power Grid. The result indicates that Rice distribution is able to effectively show the probability distribution characteristics of communication delay in WAMS during different periods of time and in different PMU substations.
