Abstract

The invention belongs to the technical field of digital physical hybrid simulation, and particularly provides a digital-analog hybrid simulation interface test platform based on double real-time simulators. The platform comprises two real-time simulators respectively simulating a digital side and a physical side, the simulators run in parallel, and the actual working condition of the hybrid simulation system is simulated through real physical interface connection. The test platform is closer to the actual working condition of the hybrid simulation system than off-line simulation, the verification of the validity of the simulation interface under different working conditions can be quickly realized through the platform, the parameters can be set on line, and the research and development process is greatly accelerated. The platform solves the problems of lack of actual working condition verification and difficulty in parameter setting in interface algorithm research.

Description

technical field [0001] The invention belongs to the technical field of digital-physical hybrid simulation, in particular to a digital-analog hybrid simulation interface test platform based on multiple real-time simulators Background technique [0002] With the large-scale grid connection of wind power, photovoltaic and other renewable energy equipment, the operation of UHV AC and DC hybrid power transmission projects, and the large-scale application of flexible AC power transmission devices and relay protection devices, the operating characteristics of the power grid and the interaction between various parts The mechanism has undergone major changes. Using digital simulation to simulate the system is difficult to accurately reflect the switching characteristics of power electronic devices, while using real physical equipment to simulate, the simulation scale is limited and the cost is high. Digital-physical hybrid simulation, also known as power hardware-in-the-loop simulat...
