摘　　要：本发明提供一种风/柴/储混合系统可靠性评估方法：采集配电网的原始数据、构建风速时间序列、构建WTG功率输出模型、构建WTG和柴油机组的停运模型、建立储能设备充放电模型、最后分块计算系统的可靠性指标；本申请提出WTG和柴油机组总功率输出大于负荷，储能设备储存能量；小于负荷，储能设备释放能量的策略，在该策略的下，建立储能设备充放电模型，进而对系统可靠性进行评估，应用这种方法计及了储能设备的运行特性，可以准确的评价混合系统的可靠性。

主权项：一种风/柴/储混合系统可靠性评估方法，具体步骤包括：步骤1：采集配电网的原始数据:电场的风速数据；WTG的切入风速、额定风速、切出风速；配电网中线路、变压器、开关设备、负荷点和WTG、储能设备及柴油发电机组之间的联接关系；储能设备的最大容量、最小容量和最大充放电功率以及柴油机组正常工作时发出额定功率；系统机组的平均无故障持续工作时间和平均修复时间；步骤2：构建风速时间序列用Weibull分布对原始风速数据进行拟合，时序产生相应的Weibull随机数，得到风速时间序列，风速的Weibull分布函数为： $f (v, c, k) = \frac{k}{c^{k}} v^{k - 1} e^{- (<关键词：法律状态：授权IPC专利分类号： G06F17/30(2006.01)Ivar ShareData = new Array();
