摘要
交直流串扰问题是造成保护误动的主要原因之一,用现有的直流系统来替代交流系统可以从源头上避免交直流串扰的发生。论文提出了系统设计方案,并分析了该方案对直流系统的影响,同时提出了解决措施。最后,通过实践验证了方案的合理性和有效性。
AC and DC interference problem is one of the most important reasons that cause misoperation;it can be fundamentally avoided when the AC system is replaced by the existing DC system.This paper presents the system design and analysis of the impact of programs on the DC system,also pointed out that measure to address.Finally,the rationality and effectiveness of the program is verified in practice.
