[0055] Example 1, RTDS dynamic model test project

[0056] A. Metallic faults in the zone: Metallic faults that occur on the lines in the zone, including single-phase, phase-to-phase, three-phase ground faults, phase-to-phase short-circuit but not ground faults, three-phase fault points at the beginning, middle and end of the line Short-circuit but not ground fault, the fault time is divided into two types: instantaneous and permanent, and the action behavior of the power grid when the power grid has or is not protected, and the action behavior and action time of the protection device are respectively assessed.

[0057] At this time, the logical operation object is the line fault point and fault time, and the fault state configuration parameters corresponding to each fault point include single-phase, inter-phase, three-phase grounding, phase-to-phase short circuit but not grounded, and three-phase short circuit but not grounded. or any reasonable combination.

Abstract

The embodiment of the invention discloses a real-time digital system (RTDS)-based platform and a method for a function test of a circuit protective relaying device. The platform mainly comprises a central control unit, a platform database, a fault database, and a platform model constructed by RTDS elements. According to the invention, the platform database saves configuration files corresponding to all submodel; the fault database saves logical operation files corresponding to the all submodels; the central control unit instructs the platform model to enter corresponding states according to the logical operation files and / or instructs the platform model to execute corresponding logical operations and / or to enter corresponding fault states according to the configuration files. According to the invention, it is clear that a test platform that is constructed on the basis of the RTDS can carry out off-line real-time checking on a circuit protective relaying device by introduction of the RTDS.

Description

technical field [0001] The invention relates to the technical field of simulation, and more specifically relates to an RTDS-based circuit relay protection device function test platform and method. Background technique [0002] With the continuous acceleration of power grid construction, the safe and stable operation of large power grids is facing unprecedented challenges, and there are increasingly higher requirements for the functions of line relay protection devices, and their functions need to be tested. The traditional non-real-time off-line security and stability analysis and calculation can no longer meet the needs. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to implement an offline and real-time functional test platform and method for a line relay protection device. [0004] In order to achieve the above purpose, embodiments of the present invention provide the following technical solutions: [000...
