Research On Improved Method Of Substation AC Loop Wiring Detection

The primary and secondary AC circuit system is an important role of substation electrical equipment system.The Practice has showed that primary and secondary AC circuit and transformer AC circuit is correct or not,seriously affecting the Fault diagnosis and protection actions,besides of this,it is essential of the safe operation of equipment.The main methods of circuit detection of the current loop system are analyzed systematically,and the shortcomings of these methods are pointed out.Taking the substation AC current and voltage loop system as the research object,a theoretical and simulation calculation model was established to conduct a comprehensive theoretical analysis of the detection methods of the TA ratio of the substations.The existing methods were supplemented and improved,To adapt to a variety of connections under the polarity,such as the correct ratio change diagnosis.By using the technology of Aliyun server and combining with the method of "cloud computing + big data",an intelligent detection system applied to wiring inspection of substation loop system was constructed.This system can easily detect on-site in terms of power flow,equipment type and so on.The research results are applied to a number of actual scenarios,which verify the correctness of the proposed method and greatly improve work efficiency.
