Research And Implementation Of Real-Time Accurate Simulation Platform For Large-Scale Stability Control System

Based on the design characteristics of the stability control system, the control strategies of each station in the system are abstracted and integrated, and classified into standardized logic and customized logic. Based on the real-time digital simulation system platform, a three-layer architecture of the real-time simulation platform for the large-scale stability control system is designed. The standardized simulator based on FPGA/DSP and the customized simulator using device virtualization technology are designed in detail. The design scheme of the real-time accurate simulation platform for large-scale stability control system is proposed. From the perspective of hardware requirements, simulation accuracy, and platform adaptability, the differences between the simulation platform and the existing real-time digital simulation test platform are compared and analyzed.

I. Introduction

With the continuous construction of UHVAC and HVDC projects and the cross-regional AC and DC interconnection of modern large-scale power grids, the grid structure and dynamic characteristics are becoming increasingly complex, bringing huge challenges to operation and control. To ensure the safe and reliable operation of large-scale power grids, assorted large-scale stability control systems have been built.
