Hardware in the Loop Test for Power System Modeling and Simulation

This paper presents a design procedure of hardware in the loop (HIL) test for power system modeling and simulation. A HIL simulation refers to a system in which parts of a pure simulation have been replaced with actual physical components. HIL simulation is often used to understand the behavior of a new device, or to predict an outcome under different system conditions without knowing the detail of device design. Additionally, a HIL test could help to build a model and validate a data model of a new power device. To efficiently evaluate the various design of controller, HIL testing is beneficial. Requirements of a real-time system simulator for active compensator systems are discussed and a general function blocks are presented. Examples of power system modeling for active compensator and relay HIL tests are presented in this paper. Finally, preliminary results and future work of HIL for relay test is presented
