Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies and shortcomings of the prior art, and propose a scientific and reliable fast tracking control method for wind power generating set power. The method of the present invention does not require additional equipment and uses the inertia and kinetic energy characteristics of the set itself to solve the problem of wind power generation. The power control problem of the generator set is too dependent on the wind condition and the slow response of the wind turbine generator to track the power target, which is conducive to the popularization and application of the wind turbine generator

Embodiment Construction

[0036] The present invention will be further described below in conjunction with specific examples.

[0037] The wind power generating set power fast tracking control method provided in this embodiment is applied to doubly-fed wind generating sets, direct-drive wind generating sets, and semi-direct-driving wind generating sets. The main components include gearboxes, wind turbines, blades, impellers, Tower, main control system, pitch control system, full power converter, double-fed inverter, step-up transformer, low voltage cabinet, high voltage ring network cabinet, etc. In fact, the fast power tracking of wind turbines is to change the current power P1. P1 is the power value calculated by the control strategy of the wind turbine, that is, the real-time power value, so that the power of the wind turbine is changed from P1 to P2. P2 is the energy management platform of the receiving wind farm. The target power value, due to the power change, there must be a difference ΔP betwee...

Abstract

The invention discloses a rapid power tracking control method for a wind generating set. The rapid power tracking control method comprises an initialization state, a rapid power control starting state, a rapid power control state and a rapid power control quitting state. By adopting the method, extra equipment is not needed, the inertia kinetic energy characteristic of the wind generating set is utilized, the problems that the wind generating set excessively depends on the wind condition to conduct power control and the wind generating set is slow in power target tracking response can be solved, and the application and popularization of the wind generating set are facilitated.

Description

technical field [0001] The invention relates to the technical field of power tracking control of a wind power generator set, in particular to a fast power tracking control method of a wind power generator set. Background technique [0002] With the country's strong support for the development of wind power generation, a large number of wind power generators will be connected to the grid, and the proportion of wind power generators in the power supply connected to the grid is getting higher and higher. At present, the power grid gradually proposes that wind turbines have short-term dispatchability and fast power target tracking capabilities, but the output of wind turbines is determined by the mechanical wind energy captured by wind turbines and the speed of wind turbines, and short-term dispatchability and fast power targets cannot be achieved. track. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies and shortcomings o...
