Method for realizing self-adaptive load balancing through multi-channel connection of intelligent management unit

Abstract

The invention relates to a method for realizing self-adaptive load balancing through multi-channel connection of an intelligent management unit. The method comprises the following steps of: importingan in-situ protection device model into a system, and enabling a balance factor N to be equal to 0; initializing a self-adaptive load balancing mode; taking an unconnected in-situ protection device, and newly starting a communication service by the general control program; obtaining remote signaling and remote measuring points of the device, and summing the remote signaling and remote measuring points with remote signaling and remote measuring points managed by the current communication service; the master control program judges whether the total telemetry and telesignalling point number of the current communication service management exceeds a threshold value or not; the current communication service is connected with the localized protection device, and remote signaling and remote measuring points managed by the current communication service are updated; and monitoring the operation of all communication services until the end. Load balance of the on-site protection intelligent management unit is achieved, the device can be upgraded independently, configuration is simple, manual intervention is not needed, and the single-point fault risk of communication service of a centralized architecture is avoided.

Description

technical field [0001] The invention belongs to the technical field of in-situ protection of electric power systems, and in particular relates to a method for multi-channel connection of an intelligent management unit to realize self-adaptive load balancing. Background technique [0002] In-situ protection technology is a new technology in the field of relay protection proposed by the State Grid Corporation of China in recent years. In-situ protection devices and intelligent management units are the latest applications of this technology in the field of relay protection. The in-situ protection device is installed close to the primary equipment, without protection, affected by external factors such as meteorological environment, geographical location, electromagnetic field, etc., and has no LCD panel. The State Grid Corporation of China proposed to use the intelligent management unit to centralize and intelligently manage the in-situ protection devices of the whole station. ...

AI Technical Summary

Problems solved by technology

The traditional centralized architecture communication service needs to maintain a large number of connections and data caches, which brings a large load and time and space overhead to the intelligent management unit (time and space overhead, referring to memory space and time consumption), which is very difficult for local protection devices and The interoperability between intelligent management units has a greater impact
