Wind turbine generator temperature control system and method based on data analysis

Abstract

The invention discloses a wind turbine generator temperature control system and method based on data analysis. The wind turbine generator temperature control system comprises a sensor group, a controller, a data processing center, a historical data uploading center, a real-time monitoring center, a real-time bearing life analysis center, a historical data uploading center and a parameter estimation timer. The dynamic wind turbine generator temperature control optimization method based on the system comprises the steps that real-time data and historical data of a wind turbine generator set areobtained, and service life prediction is conducted on the wind turbine generator set, and health state division is conducted, and different control strategies are adopted to control the wind turbine generator set. The wind turbine generator temperature control system and method have the advantages that the remaining life of the wind turbine generator can be predicted, and later management is facilitated; and the strategy control is dynamically adjusted according to the residual life of the wind turbine generator, so that the strategy control of the wind turbine generator is more suitable for the wind turbine generator, and the control strategy does not need to be changed manually, and manpower investment is reduced.

Description

technical field [0001] The invention relates to the field of wind turbine control, in particular to a data analysis-based temperature control system and method for a wind turbine generator. Background technique [0002] At present, most of the control strategies of wind turbines are a static strategy control, which does not take into account the degradation degree of the current generator bearings in real time. Most of the control strategy changes of wind farms are manual upgrades of the control version, and parameters are modified in the program. The value and parameter strategy starts and stops the air-cooled switch of the generator of the wind turbine. The use of static strategy control cannot accurately match the fan units in different states, which affects the power generation efficiency. At the same time, it takes a lot of time and effort to manually upgrade and change the control strategy by using the control version. Contents of the invention [0003] The present ...
