Advanced Control In Thermal Power Plants

This chapter describes present status of automation and its background as well as future view of advanced techniques at thermal power plants. As for the implementation of modern control theory at actual power plants for the improvement of dynamic performance, methods of steam temperature control using linear quadratic regulator or feedforward controller based on linear programming principle are respectively introduced with their control performance. In the present state of the arts, actual application of the advanced techniques, such as diagnosis and expert system to be described in the text, will largely depend on the development of technology in future.
