| 摘要:针对核电站发电机组高稳定性和高可靠性等要求，设计了一套核电控制棒驱动机构电源系统(RAM)样机。该系统样机由两台电动机-发电机组和控制柜、断路器柜组成。从无功功率分配、系统监测保护和并网设计等方面对核电控制棒驱动机构电源系统进行设计，其中并网设计是该系统样机的核心技术。通过两种并网方式优劣对比，选择加载并车电阻方式。经试验验证:样机各项性能指标满足技术要求；采用加载并车电阻并网方式，一次并车成功率超过90%，并车时间基本控制在20 s以内。 |

| Abstract:To meet with the high requirements of gensets used in nuclear power plant with regard to stability and reliability, a power system for control rod drive mechanism of nuclear power plant (RAM) prototype was developed. The RAM prototype was composed of two M.G units, control cabinet and circuit breaker cabinet. The RAM was designed from the aspects of reactive power distribution, system monitoring and protecting, and parallel performance, among which the parallel design is the core technology of this RAM prototype. By comparison of two parallel methods, load parallel resistance was selected. Tests show that the performance of the prototype meets with the technical requirements. And using load parallel resistance, the success rate of parallel at the first time is more than 90%, and the time of parallel is controlled within 20 s. |
