Fused salt energy storage power station system

Abstract

The invention discloses a fused salt energy storage power station system. The fused salt energy storage power station system comprises a cold fused salt tank, a cold fused salt pump, a steam-liquid heat exchanger, a hot fused salt tank, a hot fused salt pump, a heat exchanger set, a steam turbine generator set and a boiler; the cold fused salt tank, the cold fused salt pump, the steam-liquid heat exchanger, the hot fused salt tank, the hot fused salt pump and the heat exchanger set are connected in sequence; the boiler is connected with the steam-liquid heat exchanger, so that steam provided by the boiler heats fused salt passing through the steam-liquid heat exchanger; and after becoming into water steam through the heat exchanger set, high-pressure feed water is supplied to the steam turbine generator set for power generation. The fused salt energy storage power station system high in unit flexibility, high in frequency modulation performance, wide in unit load adjustment range, high in power generation efficiency and high in safety, reliability and economical efficiency is provided.

Description

[0001] This application claims the priority right of the patent application with application number 202110436782.3 (the filing date of the earlier application is April 22, 2021, and the title of the invention is a molten salt energy storage power station system). technical field [0002] The invention relates to the technical field of power generation, in particular to a molten salt energy storage power station system. Background technique [0003] With the increasing demand for energy and the reduction of traditional petrochemical resources, new energy generation such as wind power, photovoltaics, and hydropower has developed rapidly. However, the new energy power generation system is greatly affected by external environmental factors, and the phenomenon of abandoning wind and light is serious, which has a great impact on the stability of power grid load and frequency response, and affects the large-scale grid connection of new energy. Moreover, the peak-shaving mechanism o...

However, the new energy power generation system is greatly affected by external environmental factors, and the phenomenon of abandoned wind and light is serious, which has a great impact on the stability of the grid load and frequency response, and affects the large-scale grid connection of new energy.

Moreover, the peak-shaving mechanism of the existing power station cannot meet the new requirements of the power grid for the flexibility of the power supply side, and the existing power station cannot realize the flexible operation of the unit under any load
