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 present invention relates to wind power generators, in particular to a method for identifying the operating state of wind power generators, which is used for counting the availability of wind turbines and setting operation authority. Background technique

[0002] With the continuous increase of installed capacity of wind turbines, accurate statistics of wind turbine availability and reliable setting of operating authority have become important issues that owners and wind turbine developers must face together. According to the situation reported by the current owners of wind farms, these two problems generally exist in all major wind farms.

[0003] Due to the variability of wind farm site conditions, there are three states in the operation of wind turbines. 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 operating right to enter the wind ...

Examples

Embodiment Construction

[0021] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] In the method for identifying the operating state of a wind power generator in the present invention, a three-position mechanical active switch is respectively installed on the door of the wind power generator and the base door of the tower as a control point for the main controller to identify the operating state of the wind turbine. The wiring method obtains the position level signal of the switch, and defines the level signals of the three positions to represent the automatic state, the maintenance state, and the maintenance state respectively. For the left and right of the status bit, follow the steps below to collect the signal digital quantity of the control point:

[0023] When the fan is running normally, the switch is in the automatic state position, which is the physical zero position, and its digital quantity is "0"...
