Synchronous control method based on distributed simulation testing of transformer substation

Abstract

The invention discloses a synchronous control method based on distributed simulation testing of a transformer substation. A testing system utilizes DSP technology for performing simulation testing onaction logic between a fault point and a protecting device thereof in a power line. The testing system comprises a simulating host computer and analog amount output sub-computers. The simulating hostcomputer is connected with the analog amount output sub-computers through fibers. According to a testing method which is utilized in the invention, before a plurality of analog amount output sub-computers in front of combining unit devices with different intervals, the simulating host computer is utilized for performing long-distance synchronous controlling of simulated output through the fibers;adding testing is simultaneously performed on a plurality of combining units; a Goose signal returned from the protecting device through action can be received and a switching amount action node can be received for realizing closed-loop testing; joint debugging of an intelligent power grid system is realized; and the working condition of a total-station system in real operation is truly reflected.

Description

technical field [0001] The invention belongs to power system fault testing and simulation, in particular to a synchronous control method based on substation distributed simulation testing. Background technique [0002] The substation is the place where the voltage and current of electric energy are transformed, concentrated and distributed in the power system, so the quality of the secondary system of the substation is directly related to the normal and safe operation of the power system itself, and also to the normal and normal social economy. Development and the safety of people's lives and properties have a major impact. Especially in recent years, the great development of digital substation. The debugging of the secondary protection system of the smart substation has become the most important link. At present, the test of the relay protection system of the smart substation is mainly based on the single component test. It cannot fully and truly reflect the working condi...
