Problems solved by technology

However, there are various problems in the actual collected wind measurement data and power data. Accurate actual measurement data are needed to analyze the characteristics of wind power and power generation laws, and the data collected from wind farms usually contain abnormal data points. , resulting in the slow speed of computer data screening and sorting, so reliable and effective wind power data processing methods are needed to screen reasonable and effective data for wind power forecasting modeling

Embodiment Construction

[0012] Below in conjunction with specific embodiment, the present invention will be further described:

[0013] A wind power data processing system for a wind power station, comprising the following parts:

[0014] The acquisition module is used to collect the measured wind speed of the wind turbine within one hour, and the sampling period is set to 1 minute;

[0015] The query module is used to input the collected wind speed measured values ​​to the main control system of the wind turbine, and query the power measured values ​​of the wind turbine corresponding to these wind speed measured values;

[0016] The wind speed sequence module is used to establish a time series of wind speed measured data according to the collected wind speed measured values;

[0017] The power sequence module is used to establish a time series of power measured data according to the queried measured power value;

[0018] The data processing module is used for processing the above data.

Abstract

The invention discloses a wind electricity data processing system of a wind power station. The wind electricity data processing system of the wind power station comprises a collection module and othermodules. The randomness generated by selecting a wind power series as input is eliminated by using mutual information, less time is used for completing data insertion sorting, and thus the validity of input data needed for modeling is improved, and the forecasting accuracy of a finally built model is improved.

Description

technical field [0001] The invention belongs to the field of electric power technology. Specifically, it relates to a wind power data processing system of a wind power station. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind energy is a kind of clean and pollution-free renewable energy. It has been used by people for a long time, mainly through windmills to pump water, grind noodles, etc. Now, people are interested in how to use wind to generate electricity. The use of wind power to generate electricity is very environmentally friendly, and the wind energy reserves are huge, so it has been paid more and more attention by countries all over the world. However, there are various problems with the actually collected wind measurement data and power data. Accurate measured data is required to analyze wind power characteristics and power generation laws, and the data collected from wind farms usually contain a...
