Research on simulation model of doubly-fed electrical generating system and its OPC interface that based on matlab

In wind power area, VSCF (variable speed constant frequency) technology is commonly used, and doubly-fed generator is commonly served as the electrical machine of the wind turbine. This paper presents the principle how doubly-fed machine generates electricity and realize VSCF technology firstly. Then present a simulation model of doubly-fed electrical generating system built in Matlab. At last, talk about the OPC interface in the Matlab in order to realize the communication between the built model and the other industrial productions.
