摘要

广域测量系统(WAMS)的测量数据和管理数据均通过电力调度数据网传输，数据传输过程中在各个阶段引入的时延具有不确定性和随机性，对广域电力系统阻尼控制造成非常不利的影响。为此，提出一种对WAMS分段时延的测量方法，该方法可以有效地测量WAMS数据传输过程中各环节的时延，为保证WAMS数据的实时性和正确性提供了分析依据。在浙江省现场安装并搭建了该方法的应用平台，测量了实际现场中WAMS的分段时延并针对分段时延的特性与影响因素进行了分析。结果表明，所提出的WAMS分段时延测量方法能有效测量WAMS分段时延，通过对现场分段时延的测量和分析，为WAMS总体时延的改善提供明确的方向。

Abstract

In wide area measurement system

the to-be-measured and to-be-managed data are both transmitted through the electric power dispatching data network. The delay produced at each stage in the process of data transmission is uncertain and random

which brings about a very unfavorable impact on damping control of the wide area power system. Therefore

a measuring method of piecewise delay in the wide area measurement system is proposed

which is capable of efficiently measuring the delay of each link in the data transmission process of the wide area measurement system

providing a basis of analysis in ensuring real-time and accurate data in the wide area measurement system. In Zhejiang Province

a field application platform is set up for three substations to measure the piecewise delay and analyze the characteristics and influencing factors of piecewise delay. The results show that the measurement method of piecewise delay in the wide area measurement system is expected to provide improvement in WAMS overall time delay with definite orientation.
