ON NATURAL GAS
Engine-generators are designed for long-term continuous operation as a source of electrical energy at autonomous power plants both in autonomous and parallel operation between themselves or an industrial power grid of unlimited power. For engine-generator operation, natural gas is used in accordance with GOST 5542-87 with a pressure in front of the engine at the inlet to the pressure regulator from 1.0 to 4.0 kgf / cm2
Engine-generators are automated according to the 1st or 2nd degree of automation according to GOST 14228-80. At the 1st degree of automation, the following functions are performed:
-
automatic speed control;
-
automatic temperature control in cooling and lubrication systems;
-
automatic generator voltage regulation;
-
automatic alarm and protection (stop) based on oil and cooling water pressure, oil and water temperature;
-
control of start, stop, pre-start lubrication and speed;
-
recharging the battery.
We manufacture TDV "DIZELMASH - KGU" engine-generators automated by the 1st or 2nd degree of automation according to GOST 14228-80. At the 1st degree of automation, the following functions are performed:
-
automatic speed control;
-
automatic temperature control in cooling and lubrication systems;
-
automatic generator voltage regulation;
-
automatic alarm and protection (stop) based on oil and coolant pressure, oil and water temperature;
-
local and remote control of pre-start oil pumping, start, stop and speed;
-
warning alarm about overload of the engine-generator.
Our engine-generators have proven themselves over the years in operation in various natural and climatic conditions in more than 40 countries around the world.

FIELD OF APPLICATION
Engine-generators are used at facilities with a centralized supply of natural gas, where uninterrupted power supply is required:
at oil and gas
complexes
at food industry and agricultural enterprises
in glass and chemical plants
at housing and communal services facilities and other facilities
Our gas engine-generators DvG1A-500, DvG1A-500-1, DvG1A-630, DvG1A-630-1 and cogeneration plants based on them with an electric capacity of 500 and 630 kW correspond to code 27.11.32-35.01 "Combined cycle gas piston machines with a capacity of 7.5 kV∙A with a fuel heat utilization factor of 83% and above" are included in the Industry Classifier of Energy-Saving Products, approved by the order of the National Energy Regulatory Commission of Ukraine dated 10.12.2010 No. 159 (since 2013 - by the order of the National Energy Regulatory Commission of Ukraine dated 21.06.2013 No. 79)
