摘要
根据对已投运的高压直流输电二次系统反馈信息的分析研究,针对控制保护主机死机频繁、直流保护电路板卡故障、直流控制和保护系统不分导致保护误动等问题,在蔡家冲换流站二次系统的设计中,提出了设计改进措施,并得到了实际应用。同时还简要介绍了蔡家冲换流站二次系统国产化情况。
Based on the feedback information from HVDC power transmission secondary systems that have been put into operation, this paper presents improvements in Caijiachong station design on such problems as protection-control computer frequent crashes, DC protection circuit board failure, DC protection control system caused malfunction, etc. All the improvements have been put into practice. The domestic production conditions of the secondary system at Caijiachong station have also been briefly discussed.
