Movable combined cycle power generation system

Abstract

The invention provides a movable combined cycle power generation system which comprises a single-stage micro gas turbine power generation subsystem, a double-stage organic Rankine cycle power generation subsystem and a battery pack, wherein the single-stage micro gas turbine power generation subsystem comprises a first-stage gas compressor, a second-stage gas compressor, a combustion chamber, a turbine, a heat regenerator, a first heat exchanger, a second heat exchanger, a first air cooling generator, a first rotor and a fuel pump; the two-stage organic Rankine cycle power generation subsystemcomprises a first-stage drive pump, a second-stage drive pump, a first-stage cycle working medium, a second-stage cycle working medium, an evaporator, a first-stage expansion machine, a second-stageexpansion machine, a condenser, a condensation pump, a fuel tank, a second rotor and a second air cooling power generator; and the first air cooling generator and the second air-cooled generator supply power to the battery pack, and the battery pack supplies power to a power utilization side. The system provided by the invention has the advantages of simple flow, high integration, convenience in operation, wide adjustment range and low pollutant emission, and can improve power generation efficiency for different fuels and environmental conditions.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a movable combined cycle power generation system. Background technique [0002] Electric energy is a high-order energy in energy cascade utilization, and improving power generation efficiency is the goal pursued by every power generation system. Restricted by the size and weight of equipment, the power generation of mobile power generation systems is generally at the level of hundreds of kilowatts, and because the operating temperature and pressure of mobile power generation systems are much lower than those of fixed power generation systems, this has led to the development of mobile power generation systems. The power generation efficiency is very low, and the power generation efficiency of each mobile power generation system is difficult to exceed 20% under simple cycle conditions. Therefore, in view of the lower operating temperature and pressure conditio...
