Abstract

The invention discloses a steam-free operation system and method based on a thermal power intermediate reheating type condensing unit. The boiler is connected to the low-pressure cylinder through the high-pressure cylinder, the medium-pressure cylinder in sequence, and the outlet of the low-pressure cylinder is respectively connected to the condenser and the generator. The cooling gas produced by the high-pressure cylinder, medium-pressure cylinder and low-pressure cylinder is respectively connected to the cooler through the cooling bypass for cooling, and then after being pressurized by the booster pump, it is respectively passed into the high-pressure cylinder, medium-pressure cylinder and low-pressure cylinder for cooling. The unit of the present invention does not generate electricity after entering the no-steam operation mode, consumes the power of the power grid, improves the inertia of the power grid, plays the role of peak shaving and valley filling, and increases the power of the power grid to absorb renewable energy.

Description

technical field [0001] The invention belongs to the technical field of thermal power unit peak regulation, and in particular relates to a steam-free operation system and method based on a thermal power intermediate reheating type condensing unit. Background technique [0002] In recent years, my country's photovoltaic and wind power-based renewable energy power generation has grown rapidly, and the peak-to-valley difference in the power grid has also increased. The peak-shaving capacity of thermal power units needs to be improved urgently. The current operation and control methods of thermal power units have been difficult to meet the demand. At present, there is no precedent for the transformation of the steam-free operation system in China. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steam-free operation system and method based on a thermal power intermediate reheating condensing unit in order to solve t...
