The invention provides a method for acquiring steady-state equivalent wind speed and generated power in wind power station based on correlation analysis, belonging to the technical field of wind power generation. The method comprises the following steps: preprocessing the operational data in the wind power station; acquiring the steady-state equivalent wind speed in the wind power station by a correlation analysis method; forming a wind speed matrix, calculating correlated matrix of all unit wind speed in the wind power station, acquiring a characteristic value and a characteristic vector of the correlated matrix to obtain the equivalent wind speed finally; and acquiring the generated power in the wind power station, and the like. The method can accurately acquire the equivalent wind speed and generated power in the wind power station, and has the characteristics of high precision, simple method, convenient operation, and the like. The method has wide application range, and can be used for equivalent modeling of the wind power station, confirmation of the maximum penetration power of the wind power station, technique and system for predicating the generated power in the wind powerstation, reliability and economy application of the wind power station, analysis of influence of a wind power access network to the power system, and the like, and has great application value for planning and designing a wind power station access system.
