Embodiment Construction
[0052] The technical solutions of the present invention will be further introduced in detail below in conjunction with the accompanying drawings and specific embodiments.
[0053] In order to solve the problems of long power-limiting time, long shutdown time, and difficult start-up of some wind turbines after power-limiting of wind turbines in winter, the present invention proposes an optimal operation control method for wind turbines under the condition of power-limiting in Northeast alpine regions. In different seasons, wind turbines are operated in rotation to ensure the fairness of each wind turbine's maximum power generation and minimum downtime. This strategy fully considers the operating constraints of wind turbines and environmental factors, and rotates the wind turbines with limited power and the wind turbines in shutdown state within the entire wind turbine group. as attached figure 1 Shown is the flow chart of the wind turbine optimization operation control method ...

The invention provides an optimized operation control method for wind turbine generators. The method is characterized in that the power margins of the wind turbine generators are calculated based on real-time measured wind data and ultra-short-period wind power predicted data, the operation time and the shutdown time of the wind turbine generators are counted in real time, and the operation constraint conditions of the wind turbine generators and the influence of the environmental factors are taken into full account, and therefore, the alternate operation of the wind turbine generators in the wind power plant can be guaranteed under the premise of meeting the requirement of dispatching on the power output of the wind power plant by virtue of coordination between the operation queue and the shutdown queue of the wind turbine generators, and meanwhile, frequent start and stop of the wind turbine generators are avoided and the fairness of operation for each wind turbine generator is improved.
Description
technical field [0001] The invention belongs to the technical field of wind power generation in electric power systems, and specifically relates to how to protect the wind power generators after the power limitation control of the wind power generators in the Northeast Alpine region. Background technique [0002] With the development of my country's wind power technology and the emphasis on the development and utilization of renewable energy, wind power has developed rapidly in my country in recent years. It is preliminarily proven that 79% of my country's terrestrial wind energy that can be developed and utilized is mainly distributed in the Three North regions, and the wind resources that can be developed and utilized are 0.2TW. With the rapid increase of wind power installed operating capacity and the continuous expansion of the proportion of power supply, the impact of wind power grid connection on the system has also begun to appear in several wind power provinces such ...
