The Gansu Wind Farm Project (also called Jiuquan Wind Power Base) is a group of large wind farms under construction in western Gansu province in China ( , ). The Gansu Wind Farm Project is located in desert areas near the city of Jiuquan in two localities of Guazhou County and also near Yumen City, in the northwest province of Gansu, which has an abundance of wind resources.
This wind farm is similliar with Kashiwazaki-Kariwa Nuclear Power Plant by its capacity.
When fully completed the entire project may become the world's biggest collective windfarm.
The project is one of six national wind power megaprojects approved by the Chinese government. It is expected to grow to 20,000 megawatts by 2020, at an estimated cost of 120 billion Chinese yuan ($17.5 billion). The project is being built by more than 20 developers in two localities in Guazhou County and also near Yumen City.
The project is divided to multiple phases. The first 3,800 MW phase consists of eighteen 200 MW wind farms and two 100 MW wind farms. The second 8,000 MW phase will consist of forty 200 MW wind farms. The planned capacity is 5,160 MW by 2010, 12,710 MW by 2015 and 20,000 MW in 2020. The entire project may become the world's largest wind power producer when it is fully completed.
In 2008, construction began on a 750 kV AC power line to carry electricity from the wind farm, and construction of the wind farms themselves started in August 2009. Power is being purchased for 0.54 yuan per kWh, even though electricity from coal fired powerplants would be about half that price. Since operations began, some 6.26 billion kWh has been generated as of October 31, 2011 with 5.96 billion kWh of that produced in 2011.
As of November 2010 the project's installed capacity was 5,160 MW, which rose to approximately 6,000 MW in March 2012—roughly equivalent to the United Kingdom's entire wind power capacity at that time—with new wind turbines were being erected at the rate of 36 per day. Upon completion the entire collective project may become the world's biggest windfarm.
First phase completion
In November 2010 officials announced the completion of the project's first phase, involving the installation of over 3,500 wind turbines with an installed capacity of approximately 5,160 MW. according to Wang Jianxin, director of the Jiuquan Development and Reform Commission. At that time the project's wind parks were generating 1,150 MW.
Coordinated control centre
On March 1, 2012, a 'wind power coordinated control system' was implemented to adjust the output of the 18 wind farms of the Gansu Wind Farm Project, which total 10 million kW, to meet the needs of the transmission grid, which is limited to 1.5 million kW. This permitted the production of 1 million kWh more per day than previously, and greatly improves the system's stability.
Curtailment of wind turbine operations is a first order method for dealing with the intermittency of wind, but normally loses available output when the power grid's transmission capacity has been reached. Other methods involve either added local industrial usage or added local storage capacity.
