Abstract

The invention discloses a power control method and device of a wind power field. The wind power field comprises m power-enhanced wind generating sets, wherein m is a positive integer. The method comprises the steps as follows: when the condition that n power-enhanced wind generating sets in the m power-enhanced wind generating sets are in a nominal power generating state is monitored, the current power generation loss of a power grid is calculated on the basis of current input power of the power grid, wherein n is an integer greater than 0 and smaller than or equal to m; the sum of increasable power of the n power-enhanced wind generating sets is compared with the current power generation loss, wherein the increasable power of the power-enhanced wind generating sets is the difference between actual power and nominal power of the power-enhanced wind generating sets; and when the sum of the increasable power of the n power-enhanced wind generating sets is greater than the current power generation loss, the n power-enhanced wind generating sets are controlled, so that the sum of the increasable power of the n power-enhanced wind generating sets is equal to the current power generation loss.

Description

technical field [0001] The invention belongs to the technical field of wind power, and in particular relates to a power control method and device for a wind farm. Background technique [0002] Wind power generation is different from thermal power generation and hydropower generation, and has become a widely used power generation method, which is characterized by strong randomness and flexibility. Wind power forecasting, individualized control of wind turbines and many other means can give full play to the strong controllability of wind farms (compared to thermal power and hydropower). [0003] Horizontal axis, upwind, permanent magnet direct drive wind turbines are the main generator sets in the field of wind power generation today, including blades, hubs, generators, nacelles, towers, electronic control equipment and other large components. The blades can convert wind energy into rotational mechanical energy and then convert it into electrical energy through a generator to...
