摘要： Techniques for detecting an island in a system including a node that is operatively coupled to a primary power source (e.g., grid) and one or more distributed power generation sources are disclosed. In one embodiment, a current pulse is included in the output of a distributed power source. The grid voltage is monitored at the node to determine if a pulse-related disturbance occurs. If the grid is present, no pulse-related disturbance will manifest. If grid is down, then a pulse-related disturbance will manifest. Detection of the pulse-related disturbance is used to signal island detection.

摘要： A charging system has an alternator, a battery, and a controlled rectifier bridge between the alternator and the battery. The controlled rectifier bridge has controllable elements. A controller is provided wherein the controller controls (a) the duty cycle of the alternator field winding and (b) the switching in the controllable elements to control the phase advance angle. By utilizing a half-wave controlled rectifier bridge and three controllable elements, power output can be increased at a low overall cost. In another embodiment, the controller determines switching points for the controllable elements through a third harmonic extraction device which employs a neural network for determining the zero crossings of the third harmonic voltage obtained from a single phase voltage.
