METHOD TO DECREASE FUEL CONSUMPTION IN DIESEL POWER-GENERATING STATIONS Russian patent published in 2006 - IPC F02B63/04 F02D41/00 H02J9/00 

FIELD: power engineering; internal combustion engines.

SUBSTANCE: invention relates to diesel power-generating stations including two and more diesel generators. Proposed method to decrease consumption of fuel in diesel power-generating station servicing self-contained power systems and employing diesel generators of different power ratings, comes to the following: ac signals, by means of three-phase active power converter connected to bus of diesel power-generating station are converted into dc signals proportional to load of diesel power-generating stations which are fed to analog input of microcontroller from output of which converted signals pass to one of control units of diesel generators providing their starting and stopping. Signals from control unit pass to diesel generator from output of which signals pass to input of microcontroller, and signals from output of microcontroller pass to switch connecting diesel generator with bus of electric station. Stopping or starting of specific diesel generator is done depending on current value of consumed power basing on conditions of minimization of fuel consumption/ If load does not exceed values of power at which specific consumption of fuel of diesel generators are equal, diesel generator of lower power rating is connected, and if load power exceeds value of power at which specific fuel consumptions of diesel generator are equal, diesel generator of higher power rating is connected and diesel generator of lower power rating is disconnected. If load power exceeds value at which consumption of fuel of diesel power station is equal operation of one diesel generator of higher power rating or two diesel generators, diesel generator of lower power rating is connected together with diesel generator of higher power rating and load is distributed between them.

EFFECT: increased economy of diesel power-generating stations by decreasing summary fuel consumption.
