System and method for calculating wind power energy utilization rate

Abstract

The invention discloses a system and a method for calculating a wind power energy utilization rate. The system comprises a real-time database and a historical database, and furthermore comprises a wind power generator state online monitoring module, a wind power generator sample set data processing module, a wind power generator total generation recording service module, a wind power generator index cyclic calculation service module and a user interaction module connected with the real-time database and the historical database. The technical difficult problems of diversified wind power generator types, inconsistent wind power generator state division, low index calculation accuracy and the like during index calculation in current industry can be solved. A sample set frame is introduced and sample effective labeling is judged and processed, so that the calculation error of a single sample is reduced, the problem that theoretical generated energy cannot be calculated due to exception of the single sample is avoided, and the flexibility of calculating indexes of all dimensions is realized. The method is a universal data processing technology for calculating the indexes.

Description

technical field [0001] The invention relates to a system and method for calculating the utilization rate of wind power energy. Background technique [0002] From the perspective of the wind farm evaluation system, the current domestic availability rate is the core of the evaluation system. This index measures the performance of wind turbines and wind farms from the dimension of available time. According to a report by China Energy News in June 2015, China's wind farms have entered a stage of higher time utilization, but the average equivalent hours of wind power generation in China is not high. Under the same wind resources and power generation capacity, China's wind power assets Electricity generation is 15%-20% lower than in the US. As my country's wind power enters a stable development stage, wind power investment enterprises are gradually rationalized, shifting from simply focusing on installed capacity in the past to paying equal attention to "quantity and quality", re...
