智能变电站二次系统试验方法综述

Summary of Test Methods for Secondary System of Smart Substation

伴随经济发展及能源综合利用需求,国家电网公司提出建设坚强智能电网的目标。智能变电站作为智能电网基本要素,获得快速发展机遇。但目前仍没有一个灵活、全面、可靠的智能变电站二次系统调试试验方法,以完整地检验智能变电站二次系统的功能。首先描述了国内关于智能变电站试验方法现状,最后详细介绍一种全新的试验方法,即智能变电站全场景试验方法。该试验方法是基于电网仿真、无线同步与传输和分散注入,将实验室的试验能力带到了电力现场,为智能变电站二次系统调试提供了一种全新的试验方法。

With the development of economy and the demand of comprehensive energy utilization,the State Grid Corporation advances the goal of building a strong and smart grid.As the important part of the smart grid,the smart substation gets a fast development opportunity.But there is still no flexible,comprehensive and reliable test method for the commissioning of the secondary system of smart substation.Firstly,the current situation of the domestic test methods for smart substation is described.And then,a new test method,that is,whole scene test method of smart substation,is introduced,which is based on power grid simulation,wireless synchronization with the transmission and dispersed injection.It brings the test ability of the laboratory to the site of power system,and provides a new test method for the secondary system commissioning of smart substation.
