In the experiment of HVDC control & protection equipment, it is necessary to set up an HVDC simulation system in line with the practical projects by taking advantage of RTDS. There are many field devices and measurement & control units in actual system which can't be modeled inside RTDS due to the limitation of RTDS's simulation capacity. It is very difficult to set up the experimental system by physical devices because of their huge amounts, complicated connection. Without setting up the simulation system on these devices, many important functions in HVDC control & protection equipment, such as execution order, inter-lock logic etc., can't be tested. In order to solve the problem, the Process field simulator system (Profisim), which simulates the actual measurement & control units and field devices, has been developed, which forms a complete closed loop test system with HVDC control & protection, RTDS simulator. In summary, the Profisim system solves the bottleneck of RTDS simulator, and realizes a complete testing for HVDC control & protection equipment. The Profisim system has been successfully applied to control & protection system test of GaoLing back to back interconnection project, which shows that the test cycle is shortened, and the test quality is improved.
