±800kV特高压直流换流站绝缘配合方案研究

Research on Insulation Coordination Scheme of +800 kV UHVDC Converter Station

在科学技术的快速发展下,越来越多的先进技术形式开始被人们应用到电力行业中,±800 kV特高压直流输电就是在这样背景下出现的一种新型输电模式,并开始被电力企业广泛应用。为了能够提升800 kV特高压直流输电的安全性,需要在输电的时候做好一系列避雷操作,提升±800 kV特高压直流换流站绝缘水平。本文以某±800 kV特高压直流输电工程为基本研究对象,在阐述±800 kV特高压直流换流站绝缘配合设计原则和绝缘裕度的基础上,就±800 kV特高压直流换流站绝缘配置方案应用问题进行探究。

With the rapid development of social science and technology,more and more advanced technology forms have been applied to the power industry.Under this background,+800 kV UHVDC transmission is a new power supply mode,which has been widely used by power enterprises.In order to improve the safety of 800 kV UHVDC transmission,a series of lightning protection operations should be done well in power supply to improve the insulation level of(+800 kV UHVDC converter station).This paper takes a(+800 kV)UHVDC transmission project as the basic research object.On the basis of expounding the design principle and insulation margin of(+800 kV)UHVDC converter station insulation coordination,the application of(+800 kV)UHVDC converter station insulation configuration scheme is explored.
