Wind power station control system and wind power station

Abstract

The invention relates to a wind power station control system and a wind power station and is characterized in that the wind power station comprises a plurality of wind machines with the function of blade angle control and the wind power station control system capable of controlling each wind machine in a centralized manner, wherein the wind power station control system acquires wind velocity of each wind machine in the wind power station by a transmission interface through a communication module and calculates the average wind velocity of the wind power station via a processing module, so that when the wind power station is in a primary operation, each impeller of the wind machine firstly executes alignment process to drive the blade of each impeller of the wind machine to move to an initial position, then the rotor angle position value of common rotation speed can be calculated by using the corresponding incidence relationship between the average wind velocity and the impeller rotation speed and collocating with the operation processing rule, and then the rotor angle position value is sent to each wind machine in the wind power station by the transmission interface so as to enable each wind machine to drive each of the impellers thereof to synchronously rotate from the initial position according to the rotor angle position value, thus improving visual impact caused by the wind power station.

Description

[0001] The present invention claims the priority of the Chinese patent application with application number 200810172755.4 filed on December 12, 2008. technical field [0002] The present invention relates to a wind farm technology, more specifically, to a wind farm control system and a wind farm for synchronous operation of all wind turbines in the wind farm, and is especially suitable for wind farms close to load centers. Background technique [0003] In order to solve the problem of fossil fuel supply and the crisis of climate warming, since the 21st century, the promotion of renewable energy has received great attention, including hydropower, wind energy, solar photovoltaic, solar thermal energy, geothermal energy, biomass energy, ocean energy, etc., among which In addition, wind energy is recognized as having the greatest room for development in terms of both development scale and power generation cost. Therefore, the installed capacity and industrial scale of global wind...

Problems solved by technology

[0007] However, although the above-mentioned technology avoids the disadvantage of cost waste caused by changing the existing wind turbine hardware equipment, once the change of the shadow exceeds the set value, the wind turbine must be stopped, which will affect the power generation efficiency of the wind farm. Contrary to the original intention of setting up wind turbines

[0008] Based on the above, in view of the fact that Dispersed Generation System (Dispersed Generation System) is the future development trend of power system (Power System), the installation of wind farms is gradually approaching the load center (Load Center), that is, urban areas or industries with large power consumption The area has a high population density, so visual impairment will become an obstacle to the promotion of wind energy, which is not conducive to the popularization of renewable energy, that is, it will hinder the implementation effect of governments in promoting energy conservation and carbon reduction
