Method for the continuous operation of a synchronous generator in parallel with at least one diesel generator of an auxiliary diesel aggregate

摘要

Method for the continuous operation of a synchronous generator, which is driven by the main drive machine, in parallel with at least one diesel generator of an auxiliary diesel aggregate with or without a frequency drop, with a fixed or varying frequency in the case of separate networks. In order to facilitate correct parallel running even in the event of speed changes of the main machine, the main machine is fitted with a highly dynamic speed regulating device with which the frequency of the on-board network is regulated after synchronisation of the synchronous generator to the diesel generator. After synchronisation of the auxiliary diesel aggregate to the generator, the auxiliary diesel is switched over from frequency regulation to power regulation. During parallel running of the generators, the sum of the real power of the synchronous generator and diesel aggregate is continuously measured, from which is calculated a proportionate nominal value, taking into account the rated power of the aggregates, for the power and loading regulation, respectively, of the auxiliary diesel aggregate. After synchronisation, a previously existing load-interference control of the power regulation of the auxiliary diesel aggregate is disconnected. IMAGE
