A dual gas turbine generator set is composed of two parallel gas turbines as the power source. The two gas turbines are connected to the overrunning clutch parallel mechanism through two laminated couplings, and the overrunning clutch parallel mechanism is connected to the generator through a laminated coupling. The core components such as the laminated coupling and generator between the parallel mechanism and the generator are placed in a container with sound insulation devices, forming the main engine compartment, The main equipment and sound insulation box in the main engine compartment are installed on the overall chassis of the unit. This utility model achieves the goal of improving the power generation efficiency and saving fuel by using a type of gas turbine with a higher rated power generation gas turbine generator set and selecting a single or dual gas turbine according to the user's electricity consumption situation. It is suitable for large and medium-sized telecommunications bureaus, large enterprises, institutions, hotels, and other cities at all levels Hotels and key departments can be widely promoted and applied as backup emergency power sources during power outages.

The four processes of heating, adiabatic expansion, and isobaric heat release are completed respectively in the compressor chamber, combustion chamber, gas turbine, and regenerator or in the atmosphere. The compressor of a large gas turbine is a multi-stage axial flow type, while the small and medium-sized ones are centrifugal. Gas turbines are generally axial flow type, and in small units, centripetal type is useful. A gas turbine drives the compressor and generator. The single unit capacity of gas turbine units is about 10-20kW, and the maximum capacity has reached 140MW. The thermal efficiency ranges from 30% to 34%, with a maximum of 38%. There are two types of gas turbine structures: heavy and light, with the latter mainly modified by aviation engines. Due to its small size, light weight, fast start-up, fast installation, low or no water usage, it can use various liquid and gas fuels, and is often used for peak shaving in power generation. In addition, gas turbines are also widely used in fields such as oil and gas extraction and transportation, transportation, metallurgy, chemical engineering, and shipbuilding.
