Research on fast network protection and application of fast network protection in real power grid

Abstract

The invention discloses a research on fast network protection and application of the fast network protection in a real power grid. The fast network protection includes a system management module, a setting calculation module, a wireless sensing module, and a fault calculation module, and the setting calculation module includes line protection calculation, transformer protection calculation, bus protection calculation, and circuit breaker failure protection calculation. The self-healing, interactive, compatible, integrated, optimized, and safe characteristics of a smart power grid can be achieved by obtaining physical information such as operating state and parameters of the smart power grid through the wireless sensing module, at the same time, more comprehensive and complete power grid operation data are provided for management personnel of the operation of the smart power grid, potential safety hazards during the operation of the smart power grid are advantageously judged based on the data, an existing relay protection setting calculation module and the wireless sensing module are combined to protect the security of the smart power grid through two monitoring and protection methods to improve the security of real operation of the smart power grid.

Description

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

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a research on fast network protection and its application method in the actual power grid, which can effectively solve the problem in the actual application protection process of the traditional smart grid proposed in the above-mentioned background technology. For the fault information during operation, 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 manpower, material resources and time spent in power grid security protection The problem
