Wind driven generator operation state identification method

Abstract

A wind driven generator operation state identification method is characterized in that a three-position mechanical active switch is disposed at each of a bin gate and a tower footing gate of a wind driven generator to serve as a control point for a master controller identifying wind driven generator operation state, physical hard wiring is used to obtain a position level signal of each switch, the level signals at three positions respectively represent an automatic state, a maintenance state and a repair state. When the wind driven generator operates normally, each switch is at the automatic state position, the digital value is '0'; when maintenance staff wants to enter a bin or a tower footing gate, each switch is switched to the maintenance state to serve as a digital value input point of the master controller; when maintenance staff wants to enter a bin or a tower footing gate, each switch is switched to the repair state to serve as a digital value input point of the master controller; the signal values are used to compile program codes of master controller software wind driven generator operation state identification module. By the method, wind driven generator operation state can be identified reliably and accurately, and availability of the wind driven generator can be calculated.

Description

Technical field [0001] The invention relates to a wind power generator, and in particular to a method for identifying the running state of a wind power generator, which is used for calculating the availability rate of the wind turbine and setting operation authority. Background technique [0002] As the installed capacity of wind turbines continues to increase, accurate statistics on the availability of wind turbines and reliable setting of operating permissions have become important issues that owners and wind turbine developers must face together. According to the situation reported by the owners of the current wind farms, these two problems are common in major wind farms. [0003] Due to the variability of field conditions in the wind farm, there are three states in the operation of the wind turbine. One is the automatic state, where the control system controls the operation of the wind turbine; the other is the maintenance state, where supervisors have the right to enter the wi...

AI Technical Summary

Problems solved by technology

[0005] At present, the function of the main controller of the wind turbine to identify the maintenance status and maintenance status is completely realized by software. The logic judgment is cumbersome and complicated, the reliability is poor, and the probability of program error is high, resulting in inaccurate and true statistical data.
