Variable speed generators can improve overall genset performance by allowing the diesel\nengine to reduce its speed at lower loads. In this project, a variable speed diesel generator (VSDG)\nuses a rotating stator driven by a compensator motor. At lower loads, the stator turns in the opposite\ndirection of the rotor, a process that can be used for purposes like maintaining a fixed relative speed\nbetween the two components of a generator. This allows the diesel engine to turn at a lower speed\n(same as the rotor) and to increase its efficiency. The present research addresses the control of\nthe compensator motor driving the generatorâ??s stator using a variable-frequency drive that adapts\nthe speed to its optimal value according to the load. The performance of the proposed control\nstrategy was tested using a Freescale microcontroller card programmed in C-code to determine\nthe appropriate voltage for the variable-frequency drive. The control algorithm uses a real-time\napplication implemented on an FDRM-KL25Z signal processor board. The control performance\nof a 2 kW asynchronous motor................
