摘　　要：本文阐述了直流输电工程中直流控保系统的通讯结构,深入分析启极异常案例,发现其通讯系统存在PCIF板卡负载率高的问题。针对该问题采用修改事件运行周期的方法来达到降低PCIF板卡负载率,并在实践中得到验证。最后,提出进一步优化改进方案,意在从根本上解决通讯异常问题,从而提高直流控保系统的可靠性。This paper expounds the communication structure of control and protection system for the HVDC project, and finds that the communication systems has the problem of high load rate in board PCIF through in-depth analysis of abnormal start case. An optimization method that through modifying software event operation cycle to achieve lower load rate in board PCIF is put forward, which has been verified in practice. Finally, the further optimization and improvement scheme is provided to fundamentally resolve the problem of communication abnormality, so as to improve the reliability of the DC control and protection system.
