Real Time simulation of a turbine bypass controller

For a fast and safe start up and shut down of steam power plants, there is a growing interest in the optimization of turbine bypass controllers and actuators that are mainly used during transients. This work is focused on the development of a simple and fast code for Real Time (RT) simulation of a steam plant for the Hardware In the Loop (HIL) simulation of turbine bypass controllers and actuators. The aim is to build a Simulink library of simplified plant components such as valves, turbines, heaters and so on that could be easily assembled in order to simulate, with a very simplified approach, different plants and operating scenarios. The code is implemented for a fixed, discrete step solver and has been tested on a Texas Instrument DSP, as an example of low cost industrial hardware. In particular, two different uses of the developed code should be considered: the first one is the development of a virtual environment that should be used for HIL testing of controllers and actuators. The second one is the creation of RT models of complete plants or subsystems for the development of model based controllers.
