A fast network protection system and its application method in actual power grid

Abstract

The invention discloses a fast network protection system and an application method in an actual power grid, comprising a system management module, a setting calculation module, a wireless sensing module and a fault calculation module, the setting calculation module including line protection calculation and transformer protection calculation , bus protection calculation and circuit breaker failure protection calculation, the wireless sensor module of the present invention can make the smart grid have the characteristics of self-healing, interaction, compatibility, integration, optimization and safety by obtaining physical information such as the operating state and parameters of the smart grid, At the same time, it provides more comprehensive and complete power grid operation data for the management personnel of the smart grid operation, which is conducive to judging the potential safety hazards in the operation of the smart grid based on the data. By combining the existing relay protection setting calculation module and wireless transmission Combined with sensing modules, two monitoring and protection methods are used to protect the security of the smart grid and improve the security of the actual operation of the smart grid.

Description

technical field [0001] The invention relates to the technical field of power grid protection, in particular to a fast network protection system and an application method in an actual power grid. Background technique [0002] The smart grid is an inevitable trend in the development of the power grid. Its incomparable advantages have brought new technologies and equipment that are constantly updated in the process of building a high-performance power grid. With the continuous deepening of smart grid operation research, The relay protection technology based on the fast network has also developed relatively rapidly and entered a new stage. The increasingly wider functions and application range of the relay protection device also provide a stable development foundation for the smart grid; [0003] In the actual application protection process of the traditional smart grid, the fault information of the smart grid during operation is generally judged by its own internal computing sy...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a fast network protection system and its application method in the actual power grid, which can effectively solve the problem that the traditional smart grid in the actual application protection process mentioned in the background technology generally judges the operation of the smart grid through its own internal computing system. Only a single fault calculation module is used to calculate and judge the fault information of the smart grid, which reduces the accuracy of safety fault information and increases the cost of manpower, material resources and time spent on power grid security protection. question
