FIELD: electrical engineering.
SUBSTANCE: use: in electrical engineering for preventive control of generator set (GS) disconnection in order to protect, for example, ship electric power systems (SEPS) against overload caused by erroneous actions of crew. Device comprises a GS signal disconnection signal generating unit based on the number GS: active load sensors and operation sensors, as well as a control unit for the technical state of the disconnected GS, a single -vibrator, a unit for addition, unit for generating active load of ship electric power system (SEPS) after disconnection of disconnected GS, comparator unit, logic unit, signaling unit, consumer disconnection unit and GS disconnection unit; wherein output of GS signal disconnection unit is connected to univibrator input, output of each of active load sensors is connected to corresponding input of addition unit, output of which is connected to first input of comparator unit; output of each of operation sensors GS is connected to corresponding of first inputs of unit of formation of allowable value of active load SEPS after disconnection of disconnected GS, output of which is connected to second input of comparator unit; output of technical condition control unit of disconnected GS is connected to second input of logic unit; output of monostable multivibrator is connected to second input of SEPS active load permissible value generating unit after disconnection of disconnected GS and to third input of logic unit; output of comparison unit is connected to first input of logic unit, first output of which is connected to input of GS disconnection unit, second output of logic unit is connected to alarm unit, third output of logic unit is connected to input of consumer disconnection unit, in contrast to the prototype, additionally comprises units for monitoring the technical state of the generator units operating in parallel to the disconnected GS, and the logic unit has additional fourth inputs, wherein the output of each of the control units of the technical state of the generator units operating in parallel to the disconnected GS is connected to the corresponding of the fourth inputs of the logic unit.
EFFECT: higher safety of GS disconnection.
