Abstract

The invention discloses a supercritical carbon dioxide cycle power generation compressor control system which comprises a control system, a high-pressure buffer tank, a low-pressure buffer tank, a first adjusting valve, a second adjusting valve, a pressure stabilizing tank and a compressor. An outlet of the high-pressure buffer tank is communicated with an inlet of the surge tank through a first regulating valve, the outlet of the high-pressure buffer tank is communicated with an inlet of the compressor, and the outlet of the high-pressure buffer tank is communicated with an inlet of the low-pressure buffer tank through a second regulating valve; the control system is connected with the compressor, the first adjusting valve and the second adjusting valve. The system can meet the requirement that the compressor rapidly increases or reduces the system flow in the supercritical carbon dioxide generator set according to the power generation requirement.

Description

technical field [0001] The invention belongs to the technical field of thermal power generation, and relates to a supercritical carbon dioxide cycle power generation compressor control system. Background technique [0002] Conventional thermal power plants have developed into a bottleneck in improving cycle efficiency. Simply relying on improving the initial parameters of the unit to solve the efficiency problem of steam turbine units has been limited by high temperature and high pressure materials. At present, supercritical carbon dioxide power generation has broken through the theoretical research stage, and domestic experimental power plants have begun to be built. As a supercritical carbon dioxide unit, the compressor provides the working fluid power source for the system, and has become the most important auxiliary machine for the supercritical carbon dioxide generator. How to use it? Rapid and stable control to the pressure required for generating units has become the ...
