基于物理融合的联合仿真技术研究

In recent years, the power hardware-in-the-loop (PHIL) simulation technology of electrical systems based on real-time digital simulators has attracted widespread attention. It combines the advantages of digital simulation and physical simulation, which can effectively improve simulation accuracy and shorten the development cycle of simulation systems. However, due to the unsatisfactory power interface, the constructed PHIL simulation system will have stability problems. Based on the theory of PHIL simulation system of ideal transformer (ITM) interface algorithm, a method of introducing compensation signal into the control signal of controlled current source is proposed. The research on system stability analysis can provide guidance for meeting the needs of multi-scale system co-simulation and implementing co-simulation of different systems.
