1. A circuit arrangement for the economical utilization of primary energy converters which, fed with different primary energy, drive electric generators (2, 40, 52) which feed in parallel into a power supply (20) working in island operation with fluctuating power consumption, the output regulators (27, 28, 35, 36, 47, 48) of the primary energy converters (1, 51) being connected to an overriding frequency control (21), the generating set with the most economical primary energy conversion working as the leading generating set and the leading generating set only being relieved by the next generating set when the power supply output (SIGMA Psoll ) required exceed the instantaneous maximum available output from the leading generating set, characterised in that only after the leading generating set is working to full capacity is a desired value for the output control (35, 36) of the next generating set formed by finding the difference (32) between the required power supply output (SIGMA Psoll ) and the instantaneous maximum available output from the leading generating set, and applied to this next generating set, that further generating sets come into use if the output made available from the generating sets runnings in parallel drops below the required power supply output (SIGMA Psoll ), and that a minimum output (PDmin ) is always supplied, as a desired output, to a diesel engine (51) which only runs simultaneously as a primary energy converter, by which desired output the required power supply output (SIGMA Psoll ) is previously reduced. |
