Abstract:

As wind power technology has been an important part of the new energy technology recently, different wind power companies in various cities and provinces has deployed a large number of base stations. With the explosive growth of the wind farm, there is large number of monitoring data in transferring which needs to be taken regular troubleshooting and screening on. However the inconsistency and complexity of the data has created great difficulties for the implement of this work. To this end, a heterogeneous data analysis method based on mapping model is constructed creatively. Different types of monitoring data obtained by the controller (Beckhoff, Mita, etc.) are transmitted to the mapping model via the data input interface. There are many mapping constraints, mapping terms and mapping rules in the definition of this model, which can integrateincoming data into the same data structure. Then the data is sent to the system software platform which is connected to the output interface. Finally it is displayed on the platform after a simple image processing. Experimental results show the implementation of this method can greatly improve the speed and efficiency of daily screening.
