The Design of Wind Generating Set Yaw Control System Based on S7-1200

In the context of 2012 SIEMENS cup national college student automation industry challenge match, a Yaw control system of wind generating set is designed in this paper. The designs of the software and hardware are described in detail. Based on the software provided by the match, the debugging of the self-starting control, yaw control are completed very well. The accurate alignment toward the wind of the wind wheel is achieved. The obtain maximization of the wind energy is guaranteed, and therefore has certain practical value for the development and utilization of the wind energy.
