Design of Hardware -in -the -Loop Simulation Test System of Underwater Thermal Power System

The research of hardware - in - the - loop simulation test plays a very important role in the development of underwater thermal power system. The paper designs a hardware - in - the - loop simulation test system based on virtual instrument for some type underwater thermal power system. This system combines controller and fuel pump with computer, signal measuring device and test - bed driving unit. The design scheme is briefly described and the key technique of software and hardware design is introduced in detail. With this test system, the global experimental research is carried out, including doing dynamic and static analysis. The experimental results show that the test system has many characteristics such as high dependability, convenient and practical.
