Transmission line relay protection control service channel route configuration method and device

Abstract

The embodiment of the invention provides a transmission line relay protection control service channel route configuration method and device. The specific implementation way of the method comprises the following steps: according to information of an initial node and a terminal node in a received route configuration request, and network topology information, determining a plurality of routes between the initial node and the terminal node by adopting breadth-first search, and obtaining a first route set; determining a risk value corresponding to each route according to a node included in each route in the first route set and a risk value of each conserved node; recognizing routes that the corresponding risk values of the routes are smaller than a preset risk threshold and the born service quantity and the residual bandwidth meet a preset condition from the first route set, and acquiring a second route set; and recognizing routes of a preset first quantity threshold with smaller time delay values in the second route set, and taking the recognized routes as configured routes. By applying the embodiment of the invention, the route configuration of a relay protection service can be optimized.

Description

technical field [0001] The invention relates to the technical field of electric power communication, in particular to a routing configuration method and device for a transmission line relay protection control service channel. Background technique [0002] At present, one of the fundamental reasons for the existence and development of the power communication network is that it carries important services such as transmission line relay protection equipment, power grid security and stability equipment, and power grid dispatching automation, and information transmission for various power grid operation control and dispatching. Since these services carried on the power communication network are closely related to the production, dispatching and control of the power system, the power communication standard has high requirements on the delay, reliability, and security of the routing channels used for the transmission of these services. . Among the services carried by the power com...

[0006] However, when configuring routes based on the availability of routes, only the existence of the same node in each determined route is considered, but this method cannot guarantee that the determined routes can meet the current business transmission requirements, resulting in the security of the configured routes. When configuring routes based on load balancing, only the number of hops between routes is considered, and there is no guarantee that the determined routes can meet the current business transmission requirements, resulting in the security and availability of configured routes. not tall
