Embodiment Construction

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the method and system for invoking wind turbines of a wind farm provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0029] See figure 1 , Which shows the flow of the method for invoking wind turbines in a wind farm provided by the first embodiment of the present invention.

[0030] In step 110, the state parameters of each wind turbine in the wind farm are collected in real time. The so-called status parameters include at least one of the following parameters: cumulative running time, current continuous running time, cumulative standby time, current continuous standby time, and temperature of key components. The so-called key components may include a generator, a pitch device and a converter. In this case, the temperature T1 of the generator, the temperature T2 of the pitch device and the temperature...

Abstract

The invention belongs to the technical field of wind power generation, and particularly provides a fan utilizing method for a wind power station. The fan utilizing method mainly includes following steps: 1) acquiring status parameters of various fans in the wind power station in real time; 2) determining sequencing parameters according to the status parameters and determining fan utilizing sequence on the basis of the sequencing parameters; and 3) utilizing the corresponding fans in the wind power station on the basis of the fan utilizing sequence so that running conditions of the wind power station meet requirements of a power grid. In addition, the invention further provides a fan utilizing system of the wind power station. By the aid of the fan utilizing method and the fan utilizing system, the fans in the wind power station can be utilized reasonably, so that utilization rate, running stability and running safety of the fans are improved, and failure rate of the fans is reduced.

Description

Technical field [0001] The invention relates to the technical field of wind power generation, and in particular to a fan calling method and a fan calling system of a wind farm. Background technique [0002] With the continuous development of wind power, there are more and more wind farms with a large number of wind turbines, and they are becoming an important part of the power grid. In practical applications, wind farms often need to call the wind turbines in the farm according to the requirements of the power grid. For example, the power grid will send power demand to the wind farm in real time, and the wind farm will compare it with the entire wind farm after receiving the power demand. The output power at the time is compared, and the corresponding unit in the wind farm is called according to the compared difference, that is, the corresponding unit is adjusted or activated / deactivated. [0003] At present, the call of wind turbines in a wind farm is basically a random call, tha...
