Problems solved by technology

They are an important indicator for the management department to supervise and evaluate the daily equipment conditions of the wind farm. The current method is manually calculated by the wind farm operators by reviewing the historical data of wind farm fan operation and maintenance. However, due to the large number of wind turbines and the large time span, the analysis work Due to the heavy weight, it is difficult for the staff to make accurate judgments, and the whole process cannot be effectively supervised and controlled, resulting in the management department being unable to grasp the real production overview of the wind farm and affecting production decisions
In addition, some technologies try to calculate this indicator by using the real-time measurement points of the fan, but the maintenance (or service) status based on the PLC status of the fan cannot identify the reason why the fan is placed in the maintenance state, such as fault elimination, regular maintenance or planned shutdown
Therefore, it is impossible to effectively identify the regular inspection and maintenance of the fan or the planned shutdown event, and the flaw in the judgment logic affects the application of this method

Embodiment 1

[0071] The invention has been tested on the wind power smart operation and maintenance project, which realizes automatic calculation on the smart operation and maintenance platform, and becomes an important means for the production management department to supervise the wind farm operation and maintenance and carry out performance appraisal. The implementation of the method is described as follows:

[0072] 1) Collect and organize the field information of the three subordinate wind farm work tickets in the wind farm production management system, and extract the work ticket status, work ticket fan ID, work ticket permission start time, work ticket equipment resumption time and work ticket business type and other fields, the business type corresponding to the planned shutdown in the wind farm production management system of the enterprise is daily work;

[0073] 2) The statistical program collects the work ticket information of the previous day (statistical day) online from the ...

Abstract

The invention discloses a method for calculating electric quantity loss caused by regular check and maintenance or planned shutdown of a wind field based on a work ticket. In specific operation, the state of the work ticket, the ID of a work ticket fan, the working ticket permission starting time, the working ticket equipment re-service time and the service type of the work ticket are comprehensively considered; according to the method, the electric quantity loss of the fans which have been subjected to the regular maintenance service or the planned shutdown service on the same day of the statistical day can be calculated and counted on line, and the number of the fans which have been subjected to the regular maintenance service or the planned shutdown service can be calculated on line.

Description

technical field [0001] The invention belongs to the technical field of wind power operation and maintenance, and relates to a method for calculating the power loss of wind farm regular inspection and maintenance or planned shutdown based on a work ticket. Background technique [0002] The number of wind farm regular inspection and maintenance units refers to the number of wind farms that have undergone regular inspection and maintenance operations on the statistical day; They are both business-planned and distinct from elimination or impacted downtime. They are an important indicator for the management department to supervise and evaluate the daily equipment conditions of the wind farm. The current method is for the wind farm operators to manually calculate the wind farm operation and maintenance historical data. However, due to the large number of wind turbines and the large time span, the analysis work It is difficult for the staff to make accurate judgments, and the enti...
