Real-Time Simulation Method for Security and Stability Control System Based on Actual Device Code Encapsulation

With the incorporation of massive heterogeneous control resources on the power supply side and the load side of the new power system into stability control, the traditional hardware in-loop real-time simulation method of the power grid security and stability control system (hereinafter referred to as the "stability control system") cannot adapt to the growing scale of the stability control system and the strong coupling of the action characteristics of multiple stability control systems. Therefore, a real-time simulation method of the security and stability control system based on the actual stability control device code encapsulation is proposed. By adopting code-level transplantation and actual device code encapsulation dynamic link library and other means, the mirror real-time simulation operation of the onsite stability control device software on a general-purpose computer is realized; a visual virtual operation environment of the stability control system is developed, a high-speed field programmable gate array(FPGA) interface for simulating master-slave communication is developed , and a callback function mechanism for simulating inter -station communication is proposed , realizing the full-function virtual operation and simulation of the stability control system; finally, the simulation effect comparison and verification is carried out in combination with the actual stability control system.
