Method for online calculation of number of wind field fault elimination shutdown units based on defect list

Abstract

The invention discloses a method for online calculation of the number of wind field fault elimination shutdown units based on defect list, and the method comprises the following steps: 1), collecting the information of non-output-reduction defect units existing on the same day of a statistical day T from a wind field production management system, and forming a set A0; (2) rejecting defect lists of which the states are temporary storage, cancelling and discarding states from the set A0, obtaining effective defect lists, and forming a set A; 3) querying in the set A according to the fan ID, and if the same fan has a plurality of defect lists, only retaining one defect sheet to obtain a defect set B; 4) screening out defect lists which are closed on the same day and lasts for less than 24 hours from the defect set B, and classifying emergency defects, serious defects and general defects according to defect levels; 5) screening out defect lists created on the day T from the defect set B, and classifying the defect lists according to defect grades; (6) finding that the number of the defects after the same kind of defect sets are combined is the number of the corresponding defect elimination halts of the wind field on the statistics day T; and (7) finding that the sum of the number of the three types of defects is the number of fault elimination shutdown units of the wind field on the statistical day T. The invention provides a scientific and rapid index acquisition method for a production management department.

Description

technical field [0001] The invention belongs to the technical field of wind power operation and maintenance, and in particular relates to a method for calculating the number of wind farm fault elimination shutdown units based on defect single-line. Background technique [0002] Equipment defect management is the most important work in the daily production management of wind farms. Its goal is to improve the level of equipment management, reduce the defect occurrence rate, increase the defect elimination rate, and make the equipment run with zero defects. The number of wind farm fault elimination shutdowns is an important indicator in the defect management work. It refers to the number of wind turbines that have carried out fault elimination work on the statistical day and the duration of the elimination is less than 24 hours. It can measure the long-term shutdown of the wind farm. The overall situation of deficiencies other than fans. The current method is for wind farm ope...

Problems solved by technology

The current method is for wind farm operators to manually judge by reviewing the historical data of wind farm fan operation and maintenance. However, due to the large number of wind turbines, the large time span, and the heavy workload of analysis, it is difficult for the staff to make accurate judgments, and the whole process cannot be obtained. Effective supervision and control prevents the management department from grasping the real production overview of the wind farm and affects production decisions

In addition, some technologies try to use the real-time status of wind turbines to calculate this indicator, but the fault status, maintenance status, and offline status based on the PLC status of the fan cannot well obtain the time boundary of fan fault elimination, and the judgment logic lacks support.
