Embodiment approach

[0064] As a preferred embodiment of the present invention, the step S102 in the five-proof logic test method of the substation device includes the following steps:

[0065] Step S1021, respectively simulating the output signals of the other bay devices involved in the multiple five-defense logics according to the multiple five-defense logics related to the bay device to be tested;

[0066] For example, for the bay layer device IEDx to be tested, for the multiple five-proof logics related to it, the output signals of the other bay layer devices involved in one of the five-proof logics are simulated sequentially by computer.

[0067] Step S1023, saving the simulated output signals of the other compartment layer devices specified by the plurality of five-defense logics as a test signal template;

[0068] That is, the output signals of the other bay devices involved in all five-defense logics related to the bay device IEDx to be tested are saved as the test signal template.

Abstract

The invention relates to five-prevention logic testing method and system of a transformer substation. The method comprises the following steps of: imitating output signals of a spacer layer device relevant to five-prevention logic by a computer; inputting output signals of other spacer layer devices other than the spacer layer device to be tested relevant to the five-prevention logic to the spacer layer device to be tested, wherein five-prevention logic to be tested is prestored in the spacer layer device to be tested; comparing output signals issued by the spacer layer device to be tested according to the five-prevention logic to be tested with output signals specified by the spacer layer device to be tested according to the five-prevention logic; and dividing the five-prevention logic to be tested into accurate five-prevention logic and false five-prevention logic. The five-prevention logic testing method and system of the transformer substation can conveniently and rapidly detect the five-prevention logic of the transformer substation.

Description

technical field [0001] The invention relates to a five-proof logic test method for a substation, and also relates to a five-proof logic test system for a substation. Background technique [0002] In substation operation management, the concept of five defenses refers to anti-load opening and closing isolating switch; anti-mis-opening and mis-closing circuit breaker; anti-load closing grounding switch; . The five-prevention function is related to the safety of equipment and maintenance personnel during substation operation, and is an important function of the substation integrated automation system. The five-defense logic is the interlocking logical relationship between each device set to realize the above-mentioned five-defense functions. [0003] Usually, the substation is divided into process layer, bay layer and station control layer, and the operation of the five defenses is mainly realized through the five defense logic of the bay layer device. Any remote control com...
