摘　　要：针对核电机组一次调频能力不足的问题,采用飞轮储能阵列来辅助核电机组进行一次调频。首先,建立额定功率为1 MW、储存电量为250 kW·h的飞轮储能单元模型和额定功率4 MW、储存电量1 MW·h飞轮储能阵列,并分析其充放电特性;其次,基于粒子滤波方法,以提升核电机组一次调频积分电量贡献指数2倍为目标,提出了一种飞轮储能阵列容量配置方法;最后,根据某装机容量为1 250 MW的核电机组历史运行数据,通过仿真验证所提出的飞轮储能阵列容量配置方法。结果表明:与采用集合经验模态分解(EEMD)方法的飞轮储能阵列容量配置方法相比,基于粒子滤波方法的飞轮储能阵列容量配置方法具有更好的调频效果。Considering the insufficient primary frequency regulation capability of nuclear power unit,the flywheel energy storage array was used to assist its primary frequency regulation.The 1 MW/250 kW.h flywheel energy storage unit model and 4 MW/1 MW·h flywheel energy storage array were established,so as to analyze their charge and discharge characteristics.In order to improve the integral power contribution index of the primary frequency regulation of nuclear power unit by twice,the capacity configuration method of flywheel energy storage array was propose based on particle filtering method.According to the historical operation data of a nuclear power unit with installed capacity of 125o MW,the simulation was performed to verify the proposed method.Results show that compared with the capacity configuration method of flywheel energy storage array using the ensemble empirical mode decomposition(EEMD)method,the proposed method shows better performance of frequency regulation.
