<p>A system is provided for regulating AC electrical power delivered from a source to a load. The system has a voltage regulating device which, in use, is connected at an input side thereof to the source and at an output side thereof to the load. The voltage regulating device is controllable to vary the ratio of voltage amplitudes at the input side and the output side. The system further has a measuring arrangement for measuring the voltage amplitude and the voltage frequency at the input side. The system further has a control device for determining a desired ratio of the voltage amplitudes depending on the measured voltage amplitude and the measured voltage frequency. The control device is adapted to issue an output command to the voltage regulating device, the output command controlling the voltage regulating device to provide the voltage amplitude ratio determined by the control device.</p> |
