  • 摘要: 为解决电网一次调频性能难以估计的问题, 本文提出了基于多源数据的电网一次调频性能平行计算平台. 通过采集整合OMS (Operations management system)、WAMS (Wide area measurement system)、SCADA (Supervisory control and data acquisition)等系统的各类型一次调频数据, 以极大似然估计、数值拟合等方法构建机组一次调频性能功频图谱. 采用均方差分析建立电网一次调频性能数学模型, 基于并网运行机组的一次调频性能功频图谱, 估算出当前电网的实际一次调频性能. 算例计算表明, 本文所提出的计算方法能够有效兼顾机组类型的静态特性和运行工况的动态特性, 并以平行执行方式完成人工估算系统与实际电力系统的滚动优化, 实现了电网一次调频性能的在线全面估计, 为电网频率管理与控制提供数据决策支持.
