Embodiment 1

[0022] This method includes five parts: five-proof function modeling, measurement and control device replacement data processing, interlocking logic file analysis, interlocking logic test, and test report output. The specific description is as follows:

[0023] 1) Modeling of five defense functions

[0024] In order to implement this test method, the following provisions are made for the modeling method of the five defense functions:

[0025] a) The information model of this compartment and other compartments related to the five-defense logic must be modeled with a data template with SV (replacement) to support the replacement service.

[0026] b) For GOOSE input information at other intervals, the measurement and control device must establish a corresponding information model to accept GOOSE input data; when configuring GOOSE, the intAddr attribute in the ExtRef element in the SCD file corresponding to Inputs is a mandatory attribute, and its content The reference (reference...

Embodiment 2

[0038] Taking an incomplete string of side switches 5011 in a 500KV substation as an example, the verification process of applying this method to the interlocking logic of the measurement and control device is explained.

Abstract

The invention provides a method for checking interlock logics of an intelligent substation measuring and controlling device. The method comprises the following steps: an IEC (International Electrotechnical Commission) 61850 model satisfying requirements on checking interlock is established for the measuring and controlling device; the measuring and controlling device supports replacement of interlocking data, and the replaced data can be applied to operation of the interlock logics; a five-defense rules file is analyzed and mass replacement operations are carried out on the measuring and controlling device to acquire interlock operation results of the device so as to judge whether the interlock function satisfies the requirements. The method for checking interlock logics of the intelligent substation measuring and controlling device, provided by the invention, can be used for conveniently, rapidly and sufficiently checking the interlock logics of the measuring and controlling device.

Description

technical field [0001] The invention relates to a verification method for interlocking logic, which belongs to the technical field of substation automation. Background technique [0002] The IEC61850 standard is the latest series of standards "Substation Communication Network and System" formulated by the TC57 working group of the International Electrotechnical Commission to solve the interoperability problems faced by the substation automation system. Provide various service functions on a basis. This standard has been widely used in the field of substations at home and abroad, and is the only communication standard in the construction of domestic intelligent substations. [0003] The five defenses of the substation are to prevent mis-dividing and closing the circuit breaker, to prevent the disconnection and closing of the isolating switch with load, to prevent the live connection (closing) of the grounding wire (grounding switch), and to prevent the grounding wire (ground...
