Abstract

The invention discloses a sampling platform for a RTDS (Real Time Digital Simulator) test based on a stability control system. In a RTDS simulation test of a SCS-500 type stability control device, theproblem of long time, high wiring workload, and low efficiency in the test preparation phase is solved. The sampling platform integrates the data output part of the RTDS simulation system with the IOsampling unit of the SCS-500 type stability control device in a cabinet, and fixedly connects the temporary wiring in the test to form a standardized IO sampling unit with independent functions. Thesampling platform not only reduces the wiring work in the test preparation stage, but also regulates the design of the electric quantity output part in a model. Moreover, the sampling platform modifies an analog acquisition component in the IO sampling unit of the SCS-500 type stability control device to adapt to the signal output of the GTAO board in the data output part of the RTDS simulation system (-10V to +10V), thereby reducing the dependence on a power amplifier in the test.

Description

technical field [0001] The invention relates to a sampling platform based on the RTDS test of a stability control system, belonging to the technical field of electric power systems and automation thereof. Background technique [0002] At present, with the continuous expansion of the scale of my country's power grid, the increasing proportion of new energy sources, and the continuous operation of AC and DC UHV lines, the structure of the power grid has become increasingly complex. The safety and stability control system is becoming more and more important as the second line of defense of power grid control, and RTDS real-time digital simulation test is widely used in China as an important method to analyze system stability problems and verify safety and stability control strategies. [0003] The safety and stability control system covers a wide area, has many control levels, involves many sites, and has many control methods. The RTDS simulation test of the safety and stabilit...
