A method to abstract the typical working condition of energy storage battery for wind farms is developed,which based on measured data statistic．The typical working condition of an energy storage battery pack that installed in a certain wind farm of Hebei province is abstract with this method．The typical working condition can be used to get a series of characteristic parameters of the battery pack,which worked in the specific mode,and it can provide a certain reference to complete an evaluation system and build a practical working condition of testing standards for the energy storage batteries in the future．
