Simulator Development of 1000MW Class Ultra Super Critical Coal-Fired Power Plant with advanced control algorithm

Even though efficiency of coal-fired power plant is proportional to operating temperature, increase of operating temperature is limited by a technological level of each power plant components. It is an alternative plan to increase operating pressure up to ultra super critical (USC) point for efficiency enhancement. It is difficult to control the system in that pressure within safety guideline that many unexpected phenomena are happen because that region is highly nonlinear region. Also it is another reason for hard to control that power plant is a combination of many complicated components and controllers. In this paper, Advanced Process Control algorithm (APC), ARX and Fuzzifier, is introduced. Then control logic applied Unit step Response Optimizer, which is combination of ARX and Fuzzifier, is designed. Its performance is tested and analyzed with design guide line.
