In order to solve the problems of uncertainty and unreliability of CMS evaluation comparison methods of different manufacturers in the prior art, the invention provides a comparison method based on a wind turbine generator CMS system test performance. The method mainly comprises front-end acquisition hardware comparison and post-processing software output result comparison, and has good performance comparison stability and engineering value. According to comparison results of CMS system test performance of different manufacturers, the invention further provides a brand-new output index conversion method for different CMS systems. Output indexes of CMS systems of different manufacturers can be unified to the standards of one CMS system; the operation states of different wind turbine generators are evaluated under the same standard, and the accuracy and the working efficiency of wind turbine generator monitoring are improved.
Description
technical field [0001] The invention relates to the technical field of wind power, in particular to a performance comparison and data conversion method of a wind turbine CMS system. Background technique [0002] The wind power industry has ushered in explosive growth; as wind turbines are installed and used in large quantities, the accompanying operational failure problems have become increasingly prominent. Since wind turbines are mostly installed in high mountains, plains, seas and other tuyere places, they have been subjected to different wind conditions and even strong gusts for a long time, coupled with the influence of weather and extreme temperature differences, the mechanical failures of wind turbines occur frequently, and most of these failures are For the vibration and abnormal noise of mechanical components, the Wind Turbine Condition Monitoring System (Condition Monitoring System, hereinafter referred to as CMS) is widely used in various types of wind turbines fo...
