Abstract

The present invention discloses a method of a mobile power generation system. A power generation apparatus is respectively quickly connected, through expansion joints, to an intake assembly and an exhaust duct which are separately transported, to implement the quick installation and connection of the power generation system at the fracturing operation site. Two conveyances are respectively provided for the intake assembly and the exhaust duct to achieve more flexible adjustment during connection. While the position of the power generation apparatus is fixed, the intake assembly is moved to connect to an intake chamber of the power generation apparatus, and the exhaust duct is moved to connect to an exhaust collector of the power generation apparatus.

First claim

What is claimed is:

1. A method of a mobile power generation system, the mobile power generation system comprising a first conveyance, a second conveyance, a third conveyance, comprising the following steps:
1) mounting, on the first conveyance, a gas turbine, an intake chamber, an exhaust collector, a generator, an electric power unit, a control system and an auxiliary system;
mounting, on the second conveyance, an intake expansion joint and an intake assembly configured to provide combustion air and gas-turbine-chamber ventilation air, and connecting the intake expansion joint to the intake assembly;
mounting an exhaust duct and an exhaust expansion joint on the third conveyance;
2) moving the first conveyance to a designated position at a user site, and moving the second conveyance and the third conveyance to predetermined positions, then adjusting horizontal and vertical positions of the second conveyance by using an intake hydraulic shifter unit to connect the intake expansion joint to the intake chamber on the first conveyance, and adjusting horizontal and vertical positions of the third conveyance by using an exhaust hydraulic shifter unit to connect the exhaust expansion joint to the exhaust collector on the first conveyance; and
3) rotating the exhaust duct on the third conveyance from a horizontal position to a vertical position, connecting the exhaust duct to the exhaust expansion joint, and discharging exhaust gas to the atmosphere through the exhaust duct.

2. The method of the mobile power generation system according to claim 1 , wherein the electric power unit is configured to output electric power from the generator, and the control system comprises a gas turbine control unit and a generator control unit.

3. The method of the mobile power generation system according to claim 1 , wherein the intake assembly comprises an intake filter, an intake silencer and a ventilation fan.

4. The method of the mobile power generation system according to claim 1 , wherein the intake expansion joint comprises a combustion expansion joint and a gas-turbine-chamber ventilation expansion joint, the combustion expansion joint is connected to the intake chamber, and the gas-turbine-chamber ventilation expansion joint is connected to the gas turbine chamber.

5. The method of the mobile power generation system according to claim 1 , wherein according to different orientations of the intake chamber on the first conveyance, the second conveyance and the third conveyance are disposed on the same side, opposite sides or adjacent sides of the first conveyance when the mobile power generation system is in working state.

6. The method of the mobile power generation system according to claim 1 , wherein during connection, the second conveyance and the third conveyance are connected to the first conveyance simultaneously or sequentially through the hydraulic shifter units respectively.

7. The method of the mobile power generation system according to claim 1 , wherein the first conveyance, the second conveyance and the third conveyance are each at least one of a trailer, a truck, a skid or a barge.

8. The method of the mobile power generation system according to claim 1 , wherein the exhaust duct is horizontally disposed on the third conveyance during transportation.

9. The method of the mobile power generation system according to claim 1 , wherein the exhaust duct comprises an exhaust silencer, an exhaust stack and an exhaust elbow; the exhaust expansion joint, the exhaust elbow, the exhaust silencer and the exhaust stack are sequentially connected; and when the exhaust duct is in working state, the exhaust stack is hydraulically rotated to a vertical position.
