Evaluation System and Model for Communication Effectiveness of IoT Sensing Networks Under Complex Working Conditions in the Converter Station
The digital converter station is the hub node of a new type of power system construction,and the IoT sensing network with fusion terminals as the core is the key infrastructure of the IoT sensing system in the digital converter station.The complex electromagnetic environment and high and low temperature,salt spray corrosion,alternating heat,and humidity conditions in the digital converter station under the interaction and superposition of a variety of physical fields,these coupled interference will affect the communication effectiveness of IoT sensing network equipment in the converter station,reduce the IoT sensing network communication performance and quality of service,and affect the digital converter station comprehensive intelligent sensing capabilities and efficient intelligent operation and inspection level.Aiming at the lack of effective evaluation methods for IoT sensing network communication efficiency under complex electromagnetic environment and multi-physical fields in the digital converter station,this paper establishes a multi-level and hierarchical IoT communication effectiveness evaluation system in the converter station from four levels:basic communication capabilities,service guarantee capabilities,survival security capacity and resource utilization ability.On this basis,the support vector machine(SVM)algorithm is used to construct an evaluation model,so as to attain a speedy and precise evaluation of IoT sensing network communication effectiveness in the digital converter station and enhance the support capability of IoT sensing networks for efficient operation and digital construction of converter stations.
