| Abstract |
In order to construct an isolated grid system with overload capability, that does not need fossil fuel prime-movers, a permanently-excited synchronous machine with increased rotating mass can be used in addition to a battery-fed pulse inverter. This configuration permits balancing of primary energy supply and load demand when utilising renewable energy. As the rotational speed control cannot be influenced by mechanically-controllable driving torque, the electrical moment is controlled in addition to the voltage. The controlled circuit model is derived, a decoupled control via the voltage vector is proposed, and its mode of operation explained with the assistance of simulations. |
