Online Monitoring Method of Intelligent Substation Under Full Communication Link Distribution
At present,the safety fiber optic online monitoring method applied in intelligent substations has the problem of excessive monitoring errors.The reason is that there is asynchronous structural information asymmetry between the link topology and circuit distribution structure of the communication network in intelligent substations,and the status service of corresponding position nodes cannot be transmitted back according to the configuration parameters,resulting in actual link status service interruption.The mapping judgment information is reduced in its link importance due to link delay,This leads to deviations in the monitoring results.To this end,an optimization scheme using full communication link allocation is proposed in the method,which optimizes the global discrimination parameters by defining the coding rules for the safety fiber optic node status of the intelligent substation under full communication link allocation,calculating the importance of the online link of the substation safety node service,and outputting the results of the online monitoring of the safety fiber optic of the intelligent substation under full communication link allocation.The experimental results show that it has the ability to improve the accuracy of online monitoring and has better robustness compared to traditional methods.
