核电厂棒电源系统的设计与优化

摘要

棒电源系统是核电厂专用电气系统,由于受供电方式和负载特性的影响,在系统和设备设计时,必须采取相应的措施来满足供电和控制要求.在方家山核电厂棒电源系统的设计中,设计者通过合理的系统结构设计以及控制和保护回路的优化设计,进一步完善了棒电源系统功能,提高了核电厂运行的可靠性.%The CRDM power supply system (RAM) is a special electric system of nuclear power plant. As it is affected by the power supply mode and load performance, appropriate measures should be taken in the system and equipment design to meet the power supply requirement. After applying the digital control system, the control and protection mode should change. To meet the above requirements, in the design of Fangjiashan NPP, multi-measures are taken to improve the structure of the power supply system, main characters and connection of motor generator set, control and protection circuits, especially for the control and protection system. According to the commissioning results, the system performance meets the requirements.
