Power grid communication network switching method and device and power grid communication system

Abstract

The invention relates to a power grid communication network switching method and device and a power grid communication system. The method comprises the steps: obtaining the geographic position of a first object, and judging whether the first object is located at a ground communication network coverage center or not according to the geographic position of the first object and a preset communicationnetwork coverage area table; when the first object is not located at the coverage center of the ground communication network, determining that a target communication network is a Ka high-throughput satellite network, comparing the target communication network with a communication network accessed last time; when the target communication network is different from the communication network accessedlast time, switching the communication network to the Ka high-throughput satellite network, wherein switching of power grid communication networks in remote areas or model coverage blind areas is realized, and the stability of the communication networks is improved.

Description

technical field [0001] The invention relates to a grid communication network technology, in particular to a grid communication network switching method, device and grid communication system. Background technique [0002] In the field of power systems, terrestrial public network communication networks such as 3G, 4G, or 5G are usually used for communication. Although 4G / 5G wireless public networks have good coverage in urban areas, they are usually used in application scenarios such as high mountains and cross-sea transmission lines. There are coverage blind spots or poor coverage, which cannot fully meet the real-time communication requirements of the power grid. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a grid communication network switching method, device and grid communication system, which can effectively avoid poor communication of the grid. [0004] In a firs...
