Problems solved by technology

[0002] At present, there is no calculation method and system for the output loss of wind farms and wind turbines in China, so it is impossible to accurately calculate the output loss caused by the abnormal operation of wind farms and wind turbines, so it is also impossible to provide performance appraisal for wind farm employees, carbon reduction, etc. Provide accurate data basis for row calculation, wind farm economic benefit analysis, and settlement of various economic disputes that cause wind turbines to fail to operate normally

Embodiment Construction

[0045] Method 1 embodiment:

[0046] Such as figure 1 As shown, 101 to 113 are all wind turbines. If the number of faulty wind turbines is small and there are a large number of normal operating wind turbines around, the following method can be used to calculate the output loss of the faulty wind turbines:

[0047] The calculation of the loss of power generation can be obtained by referring to the power generation of multiple normally working wind turbines around the faulty wind turbine during the fault time period to obtain the power generation lost by the faulty wind turbine during the fault time period. The reference method is as follows:

[0048] If there are N adjacent faulty wind turbines, and the time of failure is T, select one normal operating wind turbine surrounded by these N faulty wind turbines as a reference, where I>N. Select the output power values ​​P of all sampling points of the I wind turbines in the fault time period from the database of the wind farm monit...

Abstract

The invention provides a method for calculating the output loss of a wind power field and a unit and a device thereof, relating to the technical field of wind power generation. The lost generated energy of a failed wind turbine unit within the fault time segment is obtained through referring the generated energy of a plurality of wind turbine units which work normally around the failed wind turbine unit within the fault time segment or utilizing an expert system. The invention has the advantages of calculating accurately the output loss caused by the abnormal work of the wind power field and the wind turbine units due to various causes so as to be beneficial to improving the running management level of the wind power field, providing accurate calculation basis for all application requiringoutput power loss data of wind power plants and providing accurate basis for performance evaluation of employees of the wind power plants, calculation of carbon emission reduction, economic benefit analysis of the wind power plants as well as solution of economic disputes caused by the abnormal working of the wind power plants and the wind turbine units due to various causes.

Description

technical field [0001] The invention relates to the technical field of wind power generation. Background technique [0002] At present, there is no calculation method and system for the output loss of wind farms and wind turbines in China, so it is impossible to accurately calculate the output loss caused by the abnormal operation of wind farms and wind turbines, so it is also impossible to provide performance appraisal for wind farm employees, carbon reduction, etc. Provide accurate data basis for row calculation, wind farm economic benefit analysis, and settlement of various economic disputes that cause wind turbines to fail to operate normally. Contents of the invention [0003] The purpose of the present invention is to provide a calculation method for the output loss of wind farms and units, which can accurately calculate the output loss caused by various reasons (such as human misoperation, wind farm accidents, etc.) Calculation is conducive to improving the operati...
