Mobile modular gas turbine power station

Abstract

The invention discloses a mobile modular gas turbine power station. The mobile modular gas turbine power station is formed by connecting a first vehicle, a second vehicle and a third vehicle, the first vehicle comprises a gas turbine power system, a transmission system and a semitrailer chassis system, the gas turbine power system comprises a starter, a gearbox, a high-speed coupler and an engine,the transmission system is composed of a low-speed coupler, a first bearing, a transmission shaft, a second bearing and a flexible coupler, and a second vehicle power generation and distribution system comprises a generator, a generator installing base, a generator power shaft and a power distribution cabinet. According to the mobile modular gas turbine power station, a gas turbine is adopted asa prime mover, a power generation system composed of the gas turbine is compactly integrated on a movable chassis, and by adopting a combined mode, the power system, the power generation and distribution system and an exhaust system are correspondingly placed on different mobile carrier platforms, so that modular assembly is realized, and meanwhile, an independent exhaust noise reduction system isadopted for carrying out exhaust heat dissipation and high-frequency noise reduction on the gas turbine.

Description

technical field [0001] The invention relates to the technical field of mobile power stations, in particular to a mobile modular gas turbine power station. Background technique [0002] With the progress and development of industry, the power of electric load equipment is getting higher and higher, and the quality requirements for power grid and electric energy are also getting higher and higher. For regional power supply guarantee, large temporary construction site power consumption, large power station Black start, frequency modulation and voltage regulation in large cities all require high-power temporary power supply. Constrained by the weight limit of the driving diesel engine, within the maximum requirements of national regulations on vehicles, the power that traditional mobile power vehicles can provide is relatively small, and the power of existing mobile emergency power supplies is below 3MW, which is far below Meet the above electricity demand. If you build a perm...

AI Technical Summary

Problems solved by technology

Constrained by the weight limit of the driving diesel engine, within the maximum requirements of national regulations on vehicles, the power that traditional mobile power vehicles can provide is relatively small, and the power of existing mobile emergency power supplies is below 3MW, which is far below Meet the above electricity needs

If you build a permanent power station or a temporary power station for every possible travel electricity problem, the investment will be too high, the versatility is poor, and the economic benefit is not high

[0003] To achieve 10MW-level power generation, multiple power supply vehicles are required to be used in parallel, which is complicated to operate, high in safety hazards, and high in maintenance costs

Moreover, the existing mobile power vehicles have high noise and single fuel, and can only use a single diesel as the power fuel. The low-frequency noise emitted by the diesel unit weakens slowly, and the noise of high-power power vehicles is often greater than 100dB, which cannot meet the city’s power supply requirements.

At the same time, the low-temperature start-up performance of the diesel generator is poor, which cannot meet the effect of fast start-up and fast voltage stabilization power supply
