Problems solved by technology

[0004] The embodiment of the present invention provides a precise load-shedding method for eliminating component overload after remote equipment self-switching action, which solves the problem that the existing detection component overload load-shedding device can only eliminate the overload by cutting off the load of the station, but the component overload When it is large, the shedding load of the station is seriously insufficient, and the centralized shedding of the load of a certain substation is not conducive to the technical problem of power supply guarantee in an orderly manner according to the importance of user loads

Embodiment Construction

[0022] The embodiment of the present invention provides a precise load-shedding method for eliminating component overload after the automatic switch-on action of the remote equipment. When the load is large, the shedding load of the station is seriously insufficient, and the centralized load shedding of a certain substation is not conducive to the technical problem of power supply guarantee in an orderly manner according to the importance of user loads.

[0023] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the following The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons ...

Abstract

An embodiment of the invention discloses a precise load shedding method for eliminating element overload after a remote spare power automatic switching operation. The precise load shedding method is used for solving the technical problems that the existing detection element overload load shedding device can only eliminate overload through shedding load of home station, the sheddable load quantity of the home station is seriously insufficient when element overload quantity is large, and the centralized shedding of the load of a substation is not conducive to offering power supply guarantee according to the importance of user load orderly.

Description

technical field [0001] The invention relates to the field of electric power system and automation technology, in particular to a precise load shedding method for eliminating component overload after remote standby automatic switching. Background technique [0002] In the operation of the power system, in order to solve the power supply reliability of the 110kV power grid with one power supply in series for multiple substations, there is a system consisting of 110kV remote backup self-input devices for self-injection of backup power supplies in series substations, which can isolate faults step by step The invention provides a method for realizing the self-switching power supply of the backup power supply of the series power substation, and realizes that the series power supply network restores the power supply of the loss-of-voltage substation to the greatest extent when the main power supply fails, and supplies power through another power supply. [0003] After the remote st...
