| Abstract: | 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. |
