摘要
本文基于灵绍特高压直流输电工程对南瑞PCS9550控制系统的冗余切换逻辑和原理进行分析,研究了两套冗余控制主机之间值班、备用的切换过程,以及不同工况下控制系统出现轻微、严重和紧急故障后冗余切换逻辑的响应策略。研究结果表明,两套控制系统的冗余切换首先由备用系统发起,即备用系统首先切换为值班后,原值班系统退出值班状态,在切换过程中短时出现两套控制系统同为值班的状态。该研究结果为类似工程的设计提供了参考和借鉴价值。
The NARI＇s PCS9550 is used as DC control systems in Lingshao UHVDC project, the switching logic and principle of the control system are analyzed in this paper, the active and standby switching process between the two redundant control systems is studied, and the response strategy of redundant switching logic in different fault levels is studied too. The results show that the redundant switching is initiated by the standby system first, the standby system switched to active mode first, then the original active system out of active mode, the two control systems worked on active mode together in a short time during the switching processes. The research results provide reference for similar engineering design.
