Study Of Turbine HP Inlet Pressure Control For Nuclear Power Plant

Da Ya Bay nuclear power station is the first imported nuclear power station. The turbine control system which is designed by GEC-ALSTOM is the advanced type at that time ,it comprised a advanced turbine control design idea---HP inlet pressure control (HPIPC) mode. However, some defeats during the original design caused some dynamic operation event at Da Ya Bay nuclear power plant. So does the Ling Ao nuclear power plant (phrase I) which is the exact copy of Da Ya Bay.This study will give us the theoretic concept of turbine HP inlet pressure control, including the design idea and its operation method. In this study , the fault design idea will be analyzed and the consequence will also be introduced and be tested at the plant.This study will also give out ideas to solve the original design problem. All of the implemented ideas also were tested on the plant unit and confirm that the final result were acceptable.
