Abstract: 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>

Abstract: The control system comprises detectors determining the engine speed, the load demand to which the engine is subjected and a series of basic values for a particular engine control parameter in accordance with a fixed schedule. A correction schedule has correction values for the particular parameter stored as a two dimensional array as a function of engine speed and load demand. Each of the correction values stored at the four array points in the speed/load plane which surround the prevailing engine speed and load demand are multiplied to produce a calculated correction value. A command value is determined for the particular parameter by summing a basic value and a calculated correction value. The stored values are updated to produce a series of error values, with each error value multiplied by a weighting factor for each of the array points to form four product values. The four product values are used to update the correction values stored at the four array points.
