The invention discloses a wind generation set loss electric quantity computing method, comprising the steps of: S1, collecting wind speed data of a wind generation set, and grouping the wind speed data according to time intervals; S2, generating a two-dimensional computational domain grid by each group of wind speed data according to the correspondence of the power and the wind speed; S3, dividing the computational domain grids into regions according to distribution situation; S4, determining an optimal power curve, and computing the loss electric quantity by taking the optimal power curve as a reference. Through the statistic analysis of the loss electric quantity, reason for loss of the electric quantity can be found, and thereby loss of the electric quantity is reduced, and the economic benefit of the wind power plant is improved.
