Abstract

Abstract: To avoid the availability difference between calculated value and actual value, status codes of main control system were divided into different parts according to their available properties, based on the standard IEC61400-26-1. The statistics of wind turbine downtime was based on timestamp method. The calculation method of availability was improved by taking account of the interests of owners and manufacturers, and the overall trend of the results was consistent with the SCADA Report. By counting the time and times of the status codes of the low availability unit, the improvement method could find the main reason of low availability in wind turbine and give advice to improve wind turbine availability by updating main control program. The results showed that the wind turbine availability could be increased by 2.2%, according with actual results through proposed method.

Key words: availability, main control system, improvement method, status code, timestamp method, wind turbine
