Cloud edge cooperative communication scheduling method for panoramic monitoring of extra-high voltage converter station

Abstract

The invention discloses a cloud-side cooperative communication scheduling method for panoramic monitoring of an extra-high voltage converter station, and the method comprises the steps: converting the evaluation attribute optimization of communication resources in the extra-high voltage converter station into the optimization problem of an artificial bee colony algorithm for comprehensive task attributes, and enabling each leading bee to share the information of a solution with a following bee after completing the search, after the following bees finish the searching process, if a solution is not updated after preset cycles, the solution is abandoned, the leading bee corresponding to the solution is converted into a reconnaissance bee, the reconnaissance bee generates a new solution to replace the current solution of the leading bee, then the searching process of the leading bee is returned, the current task attribute is recorded, and the optimal value is obtained; judging whether the maximum iteration period number is reached or not, and if yes, outputting the optimal comprehensive task attribute; the method has the advantages that the problems of transmission delay, uneven load and resource waste are solved, the optimal task allocation mode is selected according to different communication network modes in the extra-high voltage converter station, and when the scale of edge nodes is large, the processing speed of collected data is high.

Description

technical field [0001] The invention relates to the communication field of UHV converter stations, and more specifically relates to a cloud-side collaborative communication scheduling method for panoramic monitoring of UHV converter stations. Background technique [0002] UHV DC converter station is the core component of UHV power system, and its reliable operation plays a vital role in the sustainable development of the power industry. In order to ensure the normal operation of the UHV converter station, the measurement data of various remote control terminals and sensors in the converter station has shown exponential growth. A large amount of data needs to be sampled and processed in real time. The traditional manual data collection can no longer meet the security requirements. [0003] At present, the State Grid Corporation of China has built a large number of cloud platform master stations, which transmit the collected data to the cloud master stations for processing. A...
