A method for monitoring the status of wind turbines

Abstract

The invention discloses a monitoring method for wind turbine status. An SCADA, a turbine calculation model and part material characteristics are organically combined. The monitoring method for the wind turbine status includes the steps of wind power plant monitoring and turbine load calculation; according to wind power plant monitoring, the current status and the remaining using time of parts are involved, and the functions of key monitoring part choosing and part status sequence displaying are included; and according to turbine load calculation, two calculation modules of the turbine calculation model and a load and part service life calculation model are involved. According to the monitoring method for the wind turbine status, by analyzing the actual working status of a turbine and collected data, the turbine calculation model and the load and part service life calculation model in the interior are corrected, so that a system can be used for clearly knowing the running state of each part and conducting failure prediction on the parts during operation. The monitoring method can achieve the following functions of (1) obtaining the load of any part during turbine running more precisely, (2) obtaining the input and output power of all the parts under any working state of the turbine, and (3) conducting failure prediction on the turbine and the parts.

Description

technical field [0001] The invention relates to a monitoring method, in particular to a method for monitoring the state of a wind turbine. Background technique [0002] At present, each wind farm has a monitoring system, that is, SCADA, to realize real-time monitoring of wind farm units, but usually, this monitoring only plays the role of operating data monitoring, unit startup and shutdown, and power limit management. Various data of real-time operation of the unit It is directly related to the load on each component of the unit. The current general monitoring system does not combine the load calculation results of the unit, the material characteristics of the components and the actual operating conditions of the fan, and the load and fatigue damage of the unit components during actual use cannot be reflected in the monitoring system. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a monitoring method for the s...
