Monitoring Method of Wind Turbine State Under Cointegration Analysis
In order to solve the problem that the SCADA system of wind turbines is affected by factors such as environment and op-eration,the system often has problems such as false alarms and missing reports,through the use of cointegration analysis meth-od,the normal operation status of a 1.5MW double-fed wind turbine in a wind farm in Baotou is selected Part of the non-station-ary SCADA data below establishes a co-integration model,and obtains the co-integration residual with the operating state infor-mation of the wind turbine,and verifies the model with a set of known electrical fault data.The results show that this method can effectively reduce the response caused by environmental and operating factors in the SCADA data,accurately identify the operat-ing state of the wind turbine,and simply and effectively realize the state monitoring of the wind turbine.
