A ventilation air methane comprehensive energy power generation system

Abstract

The invention discloses a ventilation air methane comprehensive energy power generation system. The system comprises a double-pipeline gas power generation system and a photovoltaic power generation system, the double-pipeline gas power generation system and the photovoltaic power generation system are connected to a load through a busbar to supply power to the load; the load is also connected with an external power grid through the bus bar; a power meter is arranged at the external power grid; the power meter, the photovoltaic power generation system and the double-pipeline gas power generation system are all connected to the central controller; the power meter is used for detecting and acquiring a power factor at a grid-connected point of the external power grid; the power factor is sentto the central controller; the central controller is used for receiving the power factor sent by the power meter, controlling the gas inflow of the gas power generation system according to the powerfactor value, and adjusting the photovoltaic power generation system. The power factor can be automatically adjusted; gas and photovoltaic power generation systems are coordinated in a unified manner,the grid-connected point power factor is flexibly controlled, the energy comprehensive utilization rate is improved, the energy conservation and emission reduction are realized, and the two gas inletpipelines can ensure the stable operation of the gas generator set.
