摘 要：針對某換流站極間和站間通信同時發(fā)生故障問題，根據極間和站間通信的設計分析了故障原因，極間和站間通信設計不符合冗余系統(tǒng)相互獨立的原則，RS9312板卡上電容損壞是導致故障的起因，而極間和站間通信的設計缺陷則是造成故障的主要原因。研究了極間和站間通信故障對極控系統(tǒng)的影響，并提出了改進措施，為避免類似故障的發(fā)生提供參考。
關鍵詞：極控系統(tǒng)；極間通信；站間通信

Abstract: Aiming at the problems of telecommunication faults between poles and stations occurring in a converter station at the same time, this paper analyzed the fault cause according to the design of telecommunication between poles and stations. There were two reasons causing faults, one was that the design of telecommunication between poles and stations wasn’t conform to the rule that redundant systems were independent of each other, the other was that the capacitance was broken in RS9312 circuit board, moreover, the design deficiency of telecommunication between poles and stations was the main reason. This paper studied the impact of telecommunication fault between poles and stations on pole control system, putting forward the corresponding improved measures which provide certain reference value for avoiding the similar fault.
Key words:pole control system; telecommunication between poles; telecommunication between stations
