Abstract

The invention discloses a CO2 Brayton and heat pump combined cycle system of shared devices and an operation method. The CO2 Brayton and heat pump combined cycle system comprises a fused salt heat storage system, a CO2 Brayton cycle solar-thermal power generation system, a heat pump system, a low-temperature power generation system, a cold storage system and a low-temperature heat storage system, wherein several main devices such as a shared CO2 high-pressure turbine, a shared high-temperature regenerator, a shared low-temperature regenerator, a shared precooler and a shared main compressor are shared by a CO2 Brayton cycle, a heat pump cycle and a low-temperature power generation cycle, and design parameters of the devices are designed according to the highest parameters in the cycles in use. Due to the design of the shared devices, the device investment cost is greatly reduced, and the system economy is improved.

Description

technical field [0001] The invention relates to a power generation system, in particular to a CO2 Brayton and heat pump combined cycle system and an operation method for sharing equipment. Background technique [0002] Under the background of energy shortage and environmental crisis, people pay more and more attention to improving energy efficiency. Solar energy is an inexhaustible clean energy. At the current stage, solar photovoltaic technology is relatively mature, and its application is relatively photovoltaic, but its energy storage is difficult to solve. However, it is difficult for photovoltaic power generation systems to store energy. At present, the relatively mature photovoltaic energy storage supporting method is still battery energy storage, but the cost of battery energy storage is always too high, and it is difficult to avoid accidents such as fires. Energy storage needs, various types of battery energy storage are currently difficult to promote. At the same ...
