基于广域相量测量系统的电网一次调频能力预测
|
摘要
机组的一次调频能力对电网频率波动后快速恢复具有重要作用,文中关注电网实时的一次调频能力,提出了一种基于广域相量测试系统(WAMS)同步相量测量装置(PMU)数据的电网一次调频能力预测方法。该方法基于WAMS的各发电机组一次调频性能历史统计信息,从时间维度和频差维度两方面统一考虑,在单机贡献电量预测的基础上,计算得到电网在1 min内能快速调出的机组出力。该功能已在江苏电网WAMS中投入实际运行,可为电网的调度控制提供辅助决策。
The primary frequency regulation of generator is import to frequency rapid recovery of power grid, this paper focuses on the ability of primary frequency regulation, an estimate scheme based on WAMS data is proposed. Based on enormous WAMS history statistic data, date and frequency difference two factors are considered. the ability of primary frequency regulation of single generator and power grid is estimated, the program is running in Jiangsu WAMS and providing decision support for power grid dispatching control.
