Research on the adaptation of digital perception business and communication technology in digital substations

To meet the differentiated communication performance requirements for the operation and digital sensing business of substations, it is crucial to select appropriate communication technologies to build a secure, reliable, and cost-effective network. This paper first conducts a detailed analysis of the performance requirements for communication scenarios in digital substations and discusses the advantages and limitations of current mainstream communication technologies. Secondly, a multi-dimensional comprehensive evaluation model is constructed by integrating communication technology and business communication performance requirements, using a Bayesian best-worst method combined with entropy weight method for subjective and objective comprehensive analysis; finally, the weighted evaluation scores are calculated using the multi-criteria compromise solution ranking method to obtain adaptation results. The results indicate that the proposed evaluation model and adaptation algorithm provide a theoretical foundation and solution for the adaptation of digital substation sensing business an d communication technologies.
