| Abstract:The class IE excitation system of the emergency diesel engine generator used in nuclear power plants is introduced with respect to the general performance requirements and qualification requirements. The safety function of the excitation system is analyzed and the basic structure and main functions of the newly developed controllable phase compound brushless excitation system is described. The following issues are introduced in detailed, including key points of phase compound design, the characteristics of the automatic voltage regulator that conduct the safety related function and the auxiliary regulator responsible for the function enhancement not related to safety,as well as the electric isolation criteria of 1E and N1E. The research provides reference for the design and development of the 1E digital excitation system for emergency diesel engine generators. |
