A Single phase AC power supply arrangement comprises a plurality of distributed single phase AC power sources 1A, 1B, 1C and a number of electrical loads 19. Circuit breakers 33 and interconnectors 22 may be provided for the operation of said power sources in parallel and in sufficient numbers so as to meet the electrical operating requirements of the electrical loads. Measurement units 21A, 21B, 21C and load balancing and voltage compensation units 20B, 20C may be provided to measure and regulate the voltage magnitude and phase angle and achieve conditions for parallel operation of as many of the power sources as are connected into the system. The power sources may comprise either grid interface transformers, used to step down a three phase high voltage grid supply to the network working voltage, or frequency regulated single phase AC voltage generation devices. The arrangement is particularly useful to supply power to an electric railway system to meet the requirements of the traction load. |
