The invention discloses a method for optimizing a wind power system-contained unit and backup configuration in the technical field of the operation and scheduling of an electric power system. The invention adopts a technical scheme that by analyzing the output characteristics of a fan, a valve point effect generated when a turbine inlet valve is suddenly opened is considered in a traditional method for analyzing the operation expense of a thermal power generating unit, and analysis on the rotary backup capacity based on the reliability index is also added; and a mathematic model for optimizing the unit and backup capacity is established, so that an optimal configuration result is obtained, and the configuration is carried out according to the configuration result. According to the method, different treatment ways of the water power in different periods are considered, and a favorable foundation is provided for the stable economical scheduling of the electric power system containing a wind power field; and the
