Abstract

The invention relates to a rapid mechanical switch semi-physical simulation platform, and the platform comprises a PC which operates simulation software, and a rapid switch simulation device in communication connection with the PC. A simulation model is built through the simulation software, and comprises a rapid switch control protection strategy, a logic time sequence program module, and a time and speed change curve of a switch contact displacement sensor. The rapid switch simulation device receives a switching-off / switching-on instruction from a rapid switch control protection device, and transmits the switching-off / switching-on instruction to the PC. The simulation software generates simulation process data according to the switching-off / switching-on instruction, and the rapid simulation device receives the simulation process data, processes the simulation process data, and transmits the data to the rapid switch control protection device after processing. The platform can meet the demands of state change simulation of a high-speed mechanical switch simulator, is lower in cost, and is high in cost performance.

Description

technical field [0001] The invention relates to a fast mechanical switch semi-physical simulation platform, which belongs to the technical field of direct current circuit breakers. Background technique [0002] The fast mechanical switch is an important component of the DC circuit breaker. Its structure and control and protection logic are complex, and actual simulation is required before engineering application. The commonly used tools and equipment in power system simulation are RTDS / RT-LAB digital simulators. [0003] RTDS / RT-LAB (Real-time Digital Simulator) is a real-time all-digital electromagnetic transient power system simulation device. Using advanced software and hardware technology, it can perform real-time and accurate simulation of AC and DC systems, but it is expensive and requires tens of Ten thousand U.S. dollars. Contents of the invention [0004] The object of the present invention is to provide a fast mechanical switch hardware-in-the-loop simulation p...
