Abstract

The invention belongs to the technical field of electrical power system automation, in particular to an RTDS-based double-bus protection dynamic simulation experimental method. The RTDS-based double-bus protection dynamic simulation experimental method comprises the steps of: connecting a hardware board card in an RTDS machine cabinet (RACK) with peripherals required in experiment; connecting a synchronization line of a GTWIF on the RACK to a HUB; generating a configuration file config_file by reading a hardware configuration file via RSCAD, carrying out double-bus protection primary system modeling, secondary simulation quantity output modeling and switching value closed-loop control logic modeling, allocating resources according to the configuration file, compiling models to generate a drft file after modeling and downloading the drft file into the RTDS hardware board card; and carrying out dynamic simulation experimental system configuration, generating a configuration file and running the configuration file in a Runtime menu in the RSCAD software in real time, simulating various types of faults, and investigating action and behavior of a double-bus protection device. The RTDS-based double-bus protection dynamic simulation experimental method has the advantages of being universal in the models, being capable of changing fault occurring position flexibility, and achieving closed-loop control of switching value.

Description

technical field [0001] The invention belongs to the technical field of electric power system automation, and in particular relates to an RTDS-based dual-busbar protection dynamic model experiment method. Background technique [0002] The core part of the microcomputer protection device is generally composed of digital circuits, and the digital circuit communicates with the peripheral interface components to realize the functions of sampling, logic processing and switching input and output of the protection device. A typical microcomputer protection device consists of a logic processing unit (CPU), a digital I / O interface, an analog sampling interface, a human-computer interaction interface (UI) and a communication interface, and the busbar protection is undoubtedly the core protection of a substation. The busbar protection of the voltage level needs to collect and calculate the information of all intervals under the voltage level. Therefore, the test of the busbar protection...
