Problems solved by technology

[0002] At present, nearly 53% of the wind turbines generating power on the power supply side have poor power generation performance. It can be seen that there are generally problems with low wind turbine power generation performance in wind farms
At present, the analysis methods of wind turbine power generation performance are established by manually extracting relevant attributes to establish analysis models, without considering the correlation of other attributes, and the power generation performance of wind turbines cannot be comprehensively analyzed.
[0003] Traditional wind turbine power generation performance evaluation methods are mainly based on wind speed-power two-dimensional attribute data, without considering the correlation of other attributes, resulting in low accuracy of evaluation results

[0048] related information:

[0049] Multidimensional attribute selection related theory:

[0050] The basic theory of the traditional Relief method is: After iterative calculation, each dimension attribute will output a weight value, and the size of the weight value represents the correlation between the attribute and the data category. In the process of calculating the weight of each attribute, the nearest neighbor samples of each piece of sample data in the same running state and different running states are selected. , , that is: assuming sample data is the normal operating state, then ...

Abstract

The invention discloses a power supply side power generation performance evaluation method under power regulation and control. The power supply side power generation performance evaluation method comprises the following steps: S1, collecting and processing wind turbine generator field data; s2, selecting a data attribute set with high correlation with the output power of the fan from the historical data of the wind turbine generator so as to represent the power generation state of the fan, carrying out anomaly identification on the data set corresponding to the selected attribute set, and outputting a normal data set and an abnormal data set; s3, establishing a regression function for the output normal data set; s4, calculating the lost generating capacity of the wind turbine generator; and S5, judging the running performance of the fan. According to the method, the historical power generation performance of the wind turbine generator can be accurately analyzed; the power generation performance of the wind turbine generator is comprehensively evaluated, so that power grid dispatchers can accurately control and judge the power generation performance of the wind power plant, the power grid dispatchers can be assisted to optimize the energy structure according to the power generation performance of the power supply side, a reasonable power dispatching plan is made, and the absorption capacity of new energy and clean energy is improved.

Description

technical field [0001] The invention relates to power generation performance evaluation on a power source side, in particular to a method for evaluating power generation performance on a power source side under power regulation based on multidimensional attributes. Background technique [0002] At present, nearly 53% of the wind turbines generating power on the power supply side have poor power generation performance. From this, it can be seen that the problem of low power generation performance of wind turbines generally exists in wind farms. At present, the analysis methods of wind turbine power generation performance are all based on the method of artificially extracting relevant attributes to establish analysis models, without considering the correlation of other attributes, and the power generation performance of wind turbines cannot be comprehensively analyzed. [0003] Traditional wind turbine power generation performance evaluation methods are mainly based on wind sp...
