A Multi-interface Hardware-in-the-Loop Simulation Platform for System Protection in Cyber-physical Power System

Due to the demand of cross regional measurement and control, the emerging system protection has a strong dependence on the communication information system, and is increasingly affected by the real-time ability and reliability of the communication information system. Traditional power grid simulation methods can not meet the simulation requirements of today's complex power grid. Through the research of interface technology between communication devices and communication network simulation software and interface delay compensation technology, this paper establishes a multi-interface hardware-in-the-loop simulation platform of multi physical systems. Simulation tests verify the real-time ability and reliability of the platform.
