Although the reliability of wind turbines have improved over time, there is still considerable interest in improving their availability. As the generator system has a sizeable contribution to the overall failure rates of turbines, it is important to consider methods of reducing the effects of these failures on the availability of turbines. This paper examines modular concepts for wind turbine generator...
This work aims to investigate a novel fault tolerant topology for Permanent Magnet Synchronous Generator (PMSG) based Wind Power Systems (WPS), where the static power converter consists of two three-phase inverters connected in back to back configuration. The first inverter is used to control the PMSG while the other one is used to deliver power to the grid through an output filter and a line frequency...
The operation principle of a new permanent magnet(PM) brushless DC generator composed of PM machine with 12-phase rectification circuit are introduced. The phase conduction modes of the DC generator at normal and open-ircuit fault condition are analyzed. Field-circuit coupled analysis based on the 2-D finite element model is preformed, and the output characteristics of the PM brushless DC generator...
