Problems solved by technology

The data acquisition using only the operation data method is relatively simple and requires fewer data interfaces, but it lacks the very important fan operation control data, and the identification of power-cutting moments is prone to omissions
However, due to their respective limitations, the benchmark wind turbine method and the external characteristic modeling method cannot make very accurate estimates of the actual power generation of the wind farm.

Embodiment 1

[0065] like figure 1 As shown, the present invention provides a method for identifying a power outage of a fan based on operating data and control data, which includes the following steps:

[0066] 1) Data acquisition: acquire the wind farm operation data and grid-side control data that are counted at a specific frequency within a certain period of time. Among them, the wind farm operation data includes the average wind speed and average active power where i is the number of the wind turbine, and i=1,...,N, where N is the total number of wind turbines in the wind farm; the grid-side control data includes the planned active power P 全场计划 and the actual received active power P 全场接收 .

[0067] 2) Data preprocessing: The obtained wind farm operation data and grid-side control data are sorted, cleaned and preliminarily screened to obtain wind farm operation data and grid-side control data under normal operating conditions.

[0068] Among them, when preliminarily screening the...

Embodiment 2

[0135] The above-mentioned Embodiment 1 provides a method for identifying a power outage of a fan based on operation data and control data. Correspondingly, this embodiment provides a system for identifying a power outage of a fan based on operation data and control data. The identification system provided in this embodiment can implement the method for identifying the power outage of a fan based on operation data and control data of Embodiment 1, and the identification system can be implemented by software, hardware, or a combination of software and hardware. For example, the identification system may include integrated or separate functional modules or functional units to perform corresponding steps in each method of Embodiment 1. Since the identification system of this embodiment is basically similar to the method embodiment, the description process of this embodiment is relatively simple, and the relevant parts may refer to the partial description of Embodiment 1, and the e...

Embodiment 3

[0143] This embodiment provides a processing device corresponding to the method for identifying a power outage of a fan provided in Embodiment 1. The processing device may be a processing device used for a client, such as a mobile phone, a notebook computer, a tablet computer, a desktop computer, etc. The identification method of Embodiment 1 is performed.

[0144] The processing device includes a processor, a memory, a communication interface and a bus, and the processor, the memory and the communication interface are connected through the bus to complete mutual communication. A computer program that can be run on the processor is stored in the memory, and when the processor runs the computer program, the method for identifying a power outage of a fan provided in Embodiment 1 is executed.

[0145] In some implementations, the memory may be a high-speed random access memory (RAM: Random Access Memory), and may also include a non-volatile memory (non-volatile memory), such as a...

Abstract

The present invention relates to a method, system, device and storage medium for wind power limit identification, which includes the following steps: sorting, cleaning and preliminary screening of acquired wind farm operation data and power grid side control data within a certain period of time to obtain normal Wind farm operating data and grid-side control data under working conditions; power fitting is performed on the obtained wind farm operating data under normal working conditions to obtain the average power curve of wind turbines in the time period of the wind farm; according to the Based on the average power curve of wind turbines and the control data of the grid side, it is judged whether each time stamp time is curtailed, and all power curtailment times are obtained; based on the obtained average power curve of wind turbines and all power curtailment times, each power curtailment fan is identified, and each power curtailment time is obtained. Numbers of all wind turbines that are determined to be in a limited state corresponding to the moment of power cut. The invention can be widely used in the field of wind farm operation control.

Description

technical field [0001] The invention relates to a method, system, equipment and storage medium for identifying the power limitation of a fan based on operation data and control data, and belongs to the field of wind farm operation control. Background technique [0002] In recent years, the country's demand for clean energy has been increasing, and wind energy has received more and more attention due to its wide distribution, non-polluting, low-cost and other advantages, and the installed capacity of wind power has also increased rapidly. However, the wind speed and direction are affected by many factors and have very strong uncertainties. The sudden increase in the power generation of the power grid will have a certain impact on the stability of the power grid. In order to ensure the stability of the power grid transmission line, the power grid often issues power curtailment instructions to the wind farm, and these power curtailment instructions will inevitably cause certain...
