UNIVERSAL POWER MODULE Russian patent published in 2021 - IPC F02C6/00 F02C7/00 F02C9/00 

FIELD: power engineering.

SUBSTANCE: invention relates to energy generation means, intended for arrangement of local power supply system of objects remote from centralized power supply, and can be used as self-contained power source operating on different types of fuel. Universal power module comprises a gas turbine engine with an adjustable nozzle assembly, a step-down reduction gear connected to the alternating current generator via a coupling, air, fuel, oil, electric, automatic control systems providing its operation, characterized by that said equipment is made in form of independent mobile unit, and the power unit is a serial gas turbine engine with a controlled nozzle unit of a power turbine driven by a hydraulic mechanism fed from the engine oil system, providing protection of power turbine and driving units from maximum permissible rotation frequency at instantaneous discharges of electric or mechanical load of driving units, allowing to optimize power turbine rotation frequency, gas turbine engine fuel efficiency and gas temperature before high pressure turbine due to change of its throughput capacity. Fuel supply system of gas turbine engine is equipped with gas-regulating equipment unit, allowing its start-up and further operation on different types of fuel without preliminary start-up on liquid fuel and subsequent conversion to gaseous fuel. Gas turbine engine used in universal power module comprises low-emission remote two-pipe combustion chamber, flow part of which is made with possibility of access to hot part of engine turbo-compressor for maintenance and current repair directly during operation. Universal power module uses electronic digital control system of gas turbine engine, with full responsibility ensuring automatic installation and maintenance of working modes of gas turbine engine turbo compressor by changing amount of fuel when load changes to driving units, limiting gas limit temperature before high-pressure turbine, limiting speed of turbo compressors of high and low pressure, limiting frequency of rotation of power turbine and driving units.

EFFECT: technical result is to provide protection of the gas turbine engine and generator module from operational overloads, possibility of regular maintenance and current repair during operation and implementation of alternative start of gas turbine engine from different types of fuel.
