摘要
随着近年来对直流融冰技术和融冰装置进一步的研究,以及在各试点工程的实施,直流短路电流融冰法作为目前面向大型电网最为成熟可行的融冰手段之一,得到越来越广泛的应用。以500 kV桂林变直流融冰工程为例,阐述了采用12脉动换流器的固定式直流融冰兼静止型无功补偿装置(SVC)在不同的运行状态下(融冰和SVC)的控制保护的配置方案,为同类工程的建设提供技术借鉴。
In recent years,the DC short circuit method,as one of the most mature ice-melting method,is more and more popular in large power grid based on the further study on DC ice-melting technology and device as well as the successful cases of pilot projects.Taking the DC ice-melting project in 500kV Guilin substation for example,the paper makes an introduction to the control and protection configuration scheme for the fixed DC ice-melting and static var compensator（SVC） device by adopting 12-pulse inverter under different operating conditions,which can be well referenced by similar projects.
