The invention relates to the technical field of wind power equipment monitoring, and particularly discloses a monitoring method of a wind turbine. The monitoring method of the wind turbine comprises the steps that the characteristic data of a to-be-monitored structure of the wind turbine are collected; the characteristic data and the reference data of the wind turbine are acquired; the fatigue data of the to-be-monitored structure of the wind turbine are calculated according to the characteristic data and the reference data of the wind turbine; and the fatigue data are displayed. The inventionfurther discloses a monitoring system of the wind turbine. According to the monitoring method of the wind turbine, structure fatigue damage can be effectively known, the relation of unit execution action and fatigue damage can be known, damage assessment to the residual life of the wind turbine can be achieved, and the problem that structure fatigue damage cannot be evaluated by existing equipment is solved.
Description
technical field [0001] The invention relates to the technical field of wind power equipment monitoring, in particular to a wind turbine monitoring method and a wind turbine monitoring system. Background technique [0002] Since the unit design stage adopts simulation load evaluation, and the actual wind field load is complex, and the loads of different wind fields and even different aircraft positions vary greatly, so it is necessary to understand the actual unit load. [0003] The design life of the wind turbine is more than 20 years, and it needs to run continuously for a long time. It is necessary to monitor the remaining life of the unit. Due to the small characteristics of fatigue failure and fast crack growth, if manual inspection is used, it will face heavy workload, high inspection frequency, interruption of unit operation, and difficulty arrival etc. [0004] If the structure of the wind turbine fails, it will lead to catastrophic damage to the unit. In addition, f...
