Decoupling control method of multifunctional microprocessor control backup power automatic switch

Abstract

The invention belongs to a control technology of an electric power transmission and distribution network and relates to a decoupling control method of multifunctional microprocessor control backup power automatic switch. The decoupling control method of the multifunctional microprocessor control backup power automatic switch basically includes a method of controlling an expansion inner bridging line, a method of controlling inner bridging lines or a single bus segmented connecting line and a method of controlling a single bus connecting line, wherein the method of controlling expansion inner bridging line backup power automatic switch includes the steps of decoupling a standard expansion inner bridging line to two inner bridging lines, and making up a complete backup power automatic switch logic of the expansion inner bridging line under the common effect of control logics of the backup power automatic switch of the two inner bridging lines. The decoupling control method of the multifunctional microprocessor control backup power automatic switch can be applied to control of the backup power automatic switch of dual power supply, wherein the backup power automatic switch is formed by four once main connecting lines, such as the expansion inner bridging lines, the inner bridging lines and the single bus segmented connecting lines and the single bus connecting lines, of a power substation, the movement theory is simple, reliability is high, and the basic theory of the backup power automatic switch can be completely fit.

Description

technical field [0001] The invention belongs to the control technology of electric power transmission and distribution network, and relates to a decoupling control method for multifunctional microcomputer-controlled equipment automatic switching. Background technique [0002] At present, the common standby automatic switch-on (standby power automatic switch-on) devices operated in substations include substation primary main wiring as inner bridge connection, single-bus segment connection and single-bus connection backup power automatic switch-on device. When the primary main wiring of the substation is to expand the inner bridge wiring, the construction of the substation may be divided into several phases of construction, so the primary main wiring of the substation becomes the inner bridge wiring or single bus wiring, but the backup power automatic input device is It should be set according to the above-mentioned primary wiring. Therefore, it is necessary to propose an aut...
