Similarly, relay protection devices and systems support the smooth operation of smart substations, so it is very important whether the relay protection devices can operate reliably.In this thesis, HIL hardware-in-the-loop soft real-time simulation mode was used to establish an intelligent substation system model and tested relay protection devices and systems.The intelligent substation HIL simulation system used Simulink power simulation library and Matlab real-time operating system,combined with distributed real-time synchronous protocol conversion and signal generator,simulated the real operating scenarios and real-time status of primary electrical equipment in smart substations,test protection systems and devices related to protection m...
