Description

Cryogenic liquefying air energy storage power generation and its start-up and shut-down control method
Technical field
The present invention relates to energy storing and electricity generating technical field more particularly to a kind of cryogenic liquefying air energy storage power generation and its open Stop control method.
Background technology
Cryogenic liquefying air energy storage power generation was divided into for two big stages, i.e. energy storage stage and release can the stage.The energy storage stage Function is that the form that rich electric energy is converted into cryogenic liquefying air by compressor and cryogenic liquefying equipment etc. stores Come;Releasing the function in energy stage is, liquefied air is made to absorb heat of vaporization when needing power generation, forms pressure-air promotion and expands hair The acting power generation of motor group.But energy storage stage (or releasing the energy stage), existing cryogenic liquefying air energy storage power generation is complete Stop under state, cannot achieve the automatic startup of cryogenic liquefying air energy storage power generation, it also can not be in cryogenic liquefying air energy storage Under operation, realization is automatically stopped electricity generation system.Also, when cryogenic liquefying air energy storage power generation is in the energy storage stage When (or releasing the energy stage) startup program is run to a certain step, if the step sequence condition is unsatisfactory for, the operation of startup program can not be continued. That is, the operation of existing cryogenic liquefying air energy storage power generation is required to human intervention with stopping, this considerably increases workloads And human cost, and if cannot start or stop in time cryogenic liquefying air energy storage power generation, unit can influenced just Often operation.
Invention content
It can not start automatically under full cut-off state to solve existing cryogenic liquefying air energy storage systems, and in operating status Under cannot achieve and be automatically stopped, and the problem of need human intervention when a certain step sequence condition is unsatisfactory for, the embodiment of the present invention Provide a kind of cryogenic liquefying air energy storage power generation and its start-up and shut-down control method.
On the one hand the embodiment of the present invention provides a kind of cryogenic liquefying air energy storage power generation, the system comprises:It is empty Gas air inlet and air compressor machine subsystem, air purge and supercharger subsystem, booster expansion turbine and liquid air subsystem, cyropump Subsystem, air expansion power generation subsystem, circulating fan subsystem, energy storage heat accumulation and cooling subsystem and a plurality of pipeline;
