Abstract

The invention discloses a construction method, a test method and a system for a safety control device RTDS dynamic model test system. The system construction method includes: creating a first custom component, generating a Connection.def file; and a C language file associated with the Connection.def file Write the first function code to generate the main wiring model that meets the requirements of the security device RTDS dynamic model test environment through parameter settings; create the second custom component and generate the Protection.def file; the C language file associated with the Protection.def file Write the free combination of switch opening and closing under a specific delay through parameter setting to realize the second function code for simulating the action of the relay protection device; implant the Connection.def file and Protection.def file into the public component library of RTDS, Get the Connection element and Protection element. Integrating the functions of the relay protection device used for dynamic model testing with safety control devices into the simulation model reduces the workload of testers, improves the versatility of the simulation model, and reduces the test error rate.

Description

technical field [0001] The invention relates to the technical field of safety control device testing, in particular to a construction method, a test method and a system for a safety control device RTDS dynamic model test system. Background technique [0002] At present, safety control devices or systems (hereinafter referred to as safety control devices) basically require dynamic model tests before they are put into operation. The difference from conventional relay protection devices is that the safety control devices of each station are usually customized based on their actual needs, and there are large differences in their functional strategies, input and output, and application scenarios. The dynamic model test method and test wiring of the safety control device in the prior art are as follows: figure 1 and figure 2 As shown, the test method includes the following steps: ① Collect the grid structure and component parameter information of the primary system where the se...

Problems solved by technology

[0003] The above method has the following disadvantages: (1) The security devices of each station are usually customized based on their actual needs, and there are large differences in their functional strategies, input and output, and application scenarios.

Therefore, the RTDS model has poor versatility, almost one device corresponds to one RTDS model. Every time a new functional type of security control device test is carried out, it is necessary to rebuild the scene model, configure input and output signals, wiring, and debugging. Model

A lot of repetitive work directly restricts the efficiency of modeling and testing, and potentially increases the error rate in the process of modeling and rewiring

(2) As the third line of defense for the safe operation of the power grid, the safety control device is often satisfied with the action logic after the relay protection device operates. Therefore, the dynamic model test of the safety control device often needs to be connected to the relevant relay The cooperation of the protection device directly increases the difficulty of coordination during the test, increases the occupancy rate of resources such as power amplifiers and switching value conversion devices, and greatly complicates the test wiring; and the relay protection device needs to be taken into account during the test The action logic and setting of the fixed value also increase the workload of the testers
