Introduction

This guidance document is intended for owners, power companies, creditors, operators, manufacturers, consulting agencies, and supervisors in the wind power industry. When the regulatory agencies, certification bodies, insurance companies, and other interested parties exchange information about performance indicators, establish a common foundation and build An information model that provides a way to assign specific time periods to different categories of information. Calculating wind turbine availability and reliability When the indicator is used, the model provides a basis for how to allocate time. In order to explain the availability, service life, maintenance and determination of maintenance intervals for wind turbines and components, this guidance is provided. The article defines the general terminology required for wind turbines, environmental constraints, and calculations of wind turbine availability measurements. Availability The measured values are related to the power generation time of the wind turbine, taking into account environmental factors. These environmental factors include wind conditions and other weather strips Pieces, as well as the status of the grid and substation. In addition, this guidance document provides information on the capacity or capacity of wind turbines. The terminology required for the indicator. In this guidance technical document, the basic information category is enclosed in double quotation marks, and the optional information category is in bold. Said. IEC /T S61400-26 is divided into the following two parts, covering all of the above. ---IEC /T S61400-26-1 specifies the terms of time-based availability of wind turbines; ---IEC /T S61400-26-2 specifies the terminology related to the availability of wind turbines based on power generation. Wind turbine time availability

1 Scope

This guidance document specifies the general information categories for the time period specified by the wind turbine, taking into account the internal and external time of the time period. Ministry of the situation, and explain the following. --- General information categories related to wind turbine availability and other performance indicators; ---Information category priority order to distinguish the existing categories; ---Admission and exit conditions for each category of information to categorize time; ---Informative appendix includes. ● Examples of optional information categories; ● Examples of algorithms for availability and performance indicators; ● Application examples.
