Abstract :
A novel brushless synchronous machine was designed in the last few months. In order to achieve its best performance, corresponding excitation system was proposed in this paper. Electrically excited brushless synchronous machine is a kind of DC-excited generator which has two sets of wingdings on stator. An excitation current should be provided to one set of the windings. An excitation system was designed and simulated in this paper through using co-simulation technique with finite element analysis software and control system analysis software. Many parameters were detected in real time by using a variety of voltage and current sensors and then were processed by CY8CKIT-042 PSOC4 processor. In grid operation, excitation control system can adjust the reactive power from the excitation side, when running off-grid, terminal voltage is the main concern. Control strategy was proposed and dynamic performance was co-simulated by Ansoft-Simplorer and Ansoft-Maxwell. Some of the control strategies were validated by a prototype.
