500kV玉山智能变电站试验技术应用

Application of Test Technology in 500 kV Yushan Smart Substation

近年来随着纯光学互感器、IEEE1588时钟同步技术、IEC61850-9-2组网等新技术的发展,在国内一些数字化变电站中已进行了初步应用探索,这些新技术的应用对如何进行数字化变电站进行系统的性能测试评估是当前面临的一个突出难题。介绍了苏州东(玉山变)数字化间隔测试方案及经验,提出了数字化变电站测试内容及方法手段,总结了在数字化间隔测试中遇到的一些问题。

As the development of new technologies such as pure optical transformer,IEEE1588 clock synchronization technology,IEC61850-9-2 network construction etc.in recentyears,these new technologies have been preliminarily explored to be applied in some digital substations.It is a prominent problem to systematically evaluate the performance of digital substation.This paper introduces the project＇s scheme and practical experience of digital interval test in east Suzhou（Yushan substation）,proposes the content and measure of the digital substation test,and concludes some problems in the test.
