Method for operating bay level cross measuring and controlling device for sequential control of intelligent transformer substation

Abstract

The invention discloses a method for operating a bay level cross measuring and controlling device for sequential control of an intelligent transformer substation, which is used for realizing the operation of the bay level cross measuring and controlling device. The technical scheme of the invention is as follows: operating items on each bay level measuring and controlling device are arranged according to a time sequence for operating primary equipment by an intelligent terminal; data communication and connection among the bay level measuring and controlling devices are established, and the bay level measuring and controlling device previews or executes an operating queue of operation orders. Compared with the prior art, the method has the advantage that a distributed control way in which each bay level measuring and controlling device is used as a core is adopted, the data communication and connection among the bay level measuring and controlling devices are established, and single bay level cross measuring and controlling device operation control and bay cross operation control are realized on the bay level measuring and controlling device, so that a single bay level measuring and controlling device can rapidly, effectively and stably carry out bay cross operation, the advantage of a distribution scheme that the bay level monitoring and controlling device is used as the core can be better exerted, and the on-site operation efficiency is increased.

Description

technical field [0001] The invention relates to a substation control method of an electric power system, in particular to a method for automatically switching primary equipment splitting, closing and maintenance states in a single compartment or multiple compartments in an intelligent substation. Background technique [0002] At present, the domestic substation automation system has reached a relatively high technical level after years of development, and the primary equipment and secondary equipment of some important substations have high reliability and controllability, and have the conditions for implementing programmed operations. In addition, in the substation automation system, the use of programmed operation can improve the operation efficiency and correct operation rate of primary equipment and secondary equipment, and effectively prevent misoperation during operation. Proceduralized operation has gradually become the inevitable development of unattended substations....

Problems solved by technology

The advantage of centralized is that it has little impact on the existing operation and management mode of the current substation in terms of implementation. The main disadvantages are as follows: (1) Centralized control of all programmed operations may cause failure of station control layer equipment that implements programmed operations. Programmatic operation

(2) In the centralized scheme, each single-step operation is issued by the programmed monitoring server or telecontrol workstation, and is executed by the controlled measurement and control device, so the communication efficiency is low

(3) The programmed operation is simply realized by the monitoring server or telecontrol workstation. There is an unconventional interface between the telecontrol workstation and the monitoring server, and it violates the principle of layered distribution of station control layer equipment settings, which greatly changes the structure of the power system. , affecting the safety and reliability of programmed operations

[0013] Chinese patent application number 201010034269.3 discloses a substation programmed control system based on the integrated five-defense operation ticket system, which proposes to configure the operation items that can be programmed to be controlled from the operation tickets that have been rehearsed, and complete them automatically by remote control in sequence. The system focuses on the automatic configuration of the monitoring server and the traditional cooperative execution of operation item commands by a single measurement and control device, and does not involve the implementation of complex work tickets such as typical single-interval cross-device work tickets and cross-interval work tickets on a single measurement and control device. It belongs to the centralized scheme with monitoring server or telecontrol workstation as the core
