Remote Monitoring Method of Direct Current Power Supply Fault in Smart Substation Based on Wireless Communication
In order to improve the reliability of direct current power operation and realize the accurate monitoring of its faults,combined with the application of wireless communication technology,take a smart substation as an example to design the remote monitoring method of direct current power failure.Wireless communication sampling parameters are designed to collect the operation data of direct current power supply in smart substation,introduce zero-point digital filter,establish linear difference equation for sampling signal,obtain the anti-interference filtering processing of sampling data;establish the principal component function,and adopt hidden semi-Markov model,based on the remote wireless monitoring of power failure.The comparative experimental results show that this method can not only realize the accurate monitoring of power failure,but also has a powerful remote monitoring ability,which can adapt to various complex working scenarios.
