Embodiment Construction
[0031] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0032] figure 1 It is a schematic diagram of the structure of the coal-fired power unit before transformation. The coal-fired power unit is composed of a coal-fired boiler system (1), a steam power generation system (2) and a power transmission and transformation system (3); the coal-fired boiler system (1) passes through the main steam pipe The main steam pipeline (6) and the return pipeline (7) are connected in parallel; the steam power generation system (1) is connected to the steam power generation system (1) through the cable (5) Power transmission and transformation system (3) connection.
[0033] figure 2 It is a structural schematic diagram of a process route for transforming a standby coal-fired power unit and a new system formed in the present invention. A process route for transforming a standby coal-fired power unit and a new system fo...

Abstract
The process route is characterized in that the new system formed by transforming the coal power unit exerts the normal starting function of the coal power unit during the emergency starting period of the coal power unit; the formed new system plays a green energy storage function during the long-term shutdown period of the coal power unit; an adopted process route is that an electric energy storage system (8) is parallel to a coal-fired boiler system (1) of a coal power unit, and an original steam power generation system (2) and a power transmission and transformation system (3) of an old coal power unit are utilized. According to the invention, the function of a green energy storage power station is played during the normal long-term shutdown period of a coal power unit, wind power and photovoltaic power can be consumed, and a'reservoir 'of green power is formed; the reduction loss of equipment performance and huge depreciation value reduction of assets caused by long-term idle of a large amount of coal power capital due to long-term shutdown of the coal power unit are avoided, and employment posts of the coal power industry are reduced. The method is mainly applied to transformation of long-term shutdown and emergency start of coal power units.
Description
technical field [0001] The invention belongs to the technical field of transforming coal-fired power units, in particular to a process route and a new system for transforming standby coal-fired power sets. Background technique [0002] The power industry is one of the major industries that consume coal. The normal long-term shutdown and emergency start-up of medium-sized coal-fired units is an effective way to optimize the power structure and improve energy utilization efficiency. Units that meet the requirements of policies and standards for energy efficiency, environmental protection, and safety can be “shut down without demolition” and function as emergency backup power sources when there is no need to rebuild the original site or “retreat from the city to the suburbs” for construction in a different place. Scientifically identify and exit the emergency standby unit, strictly control the operation and scheduling management of the emergency standby power supply, shut down...
