Abstract

The invention discloses a gas turbine power generation system and method. The gas turbine power generation system comprises a renewable energy power generation device, a hydrogen production device, a hydrogen energy storage device and a gas turbine. The renewable energy power generation device is used for supplying power to the hydrogen production device so that the hydrogen production device can produce hydrogen and oxygen, the hydrogen energy storage device is connected with the hydrogen production device, and the gas turbine is correspondingly connected with the hydrogen production device and the hydrogen energy storage device; and hydrogen produced by the hydrogen production device can enter the hydrogen energy storage device and the gas turbine, and the gas turbine can use air, the hydrogen prepared by the hydrogen production device and / or the hydrogen in the hydrogen energy storage device for power generation. According to the gas turbine power generation system, the hydrogen energy storage device is arranged, continuous and stable power generation of the gas turbine is guaranteed through clean energy, and the overall power generation efficiency of the gas turbine power generation system is improved.

Description

technical field [0001] The invention relates to the technical field of power generation systems, in particular to a gas turbine power generation system and a power generation method. Background technique [0002] Gas turbines generally use traditional fossil energy as fuel, such as natural gas, gasoline, and diesel. Under the background of energy shortage, environmental protection, and climate change, etc., the development of clean energy, the development of low-carbon economy, and the realization of optimal energy allocation have become the world's The common choice of all countries. [0003] In related technologies, there have been gas turbines using hydrogen as fuel, but the preparation of hydrogen also requires power consumption. Using renewable energy such as wind energy and solar energy to generate electricity and then preparing hydrogen by electrolysis is a clean and environmentally friendly hydrogen preparation method. However, due to the intermittent nature of rene...

Problems solved by technology

[0003] In related technologies, there have been gas turbines using hydrogen as fuel, but the preparation of hydrogen also requires power consumption. Using renewable energy such as wind energy and solar energy to generate electricity and then preparing hydrogen by electrolysis is a clean and environmentally friendly hydrogen preparation method. However, due to the intermittent nature of renewable energy, photovoltaic and wind power usually have an annual working time of 1,000 to 2,000 hours, and if the gas turbine works continuously, the annual working time is 8,000 hours. The two cannot be fully matched, and the gas turbine cannot generate electricity continuously and stably
