Abstract

The invention discloses a system and method for calculating the utilization rate of wind power energy, which includes a real-time database and a historical database, and also includes an online monitoring module for the status of a wind power generator connected to the real-time database and the historical database, and a data processing module for a sample group of a wind power generator , wind turbine total power generation recording service module, wind turbine indicator period calculation service module and user interaction module, which can solve the current problems in the industry when calculating this indicator, such as diverse wind turbine models, inconsistent status division of wind turbines, and index Low calculation accuracy and other technical problems. At the same time, the sample group framework introduced by it and the judgment and processing of the effective marks of samples reduce the calculation error of a single sample, avoid the problem that the theoretical power generation cannot be calculated due to the abnormality of a single sample, and realize the flexible calculation of indicators of each dimension It is a general data processing technique for calculating such indicators.

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...
