The invention provides a reliability analysis method and system for a wind power station. The method comprises the following steps: acquiring state data of each wind power set; calculating an available coefficient of each wind turbine generator set based on the state data of each wind turbine generator set; calculating the available coefficient of the wind power plant and the output power of the wind power plant based on the parameters of the wind power plant and the available coefficient of each wind generator set; and based on the available coefficient of the wind power plant and the output power of the wind power plant, selecting a reliability index and performing reliability analysis on the wind power plant to obtain a reliability analysis result. Reliability analysis is carried out on the wind power station hierarchically, fault detection and maintenance are carried out according to the reliability analysis result, the stability of future output power of the wind power station is maintained through the p
