Abstract
(EN)
A cascaded power generation system combining magnetic levitation-based ORC power generators for utilizing medium/low temperature geothermal energy comprises a primary ORC power generator assembly and a secondary ORC power generator assembly. The primary ORC power generator assembly comprises a primary evaporator (10) used to evaporate a first working substance, a primary power generator (101) connected to the primary evaporator (10), a secondary evaporator (20) connected to the primary power generator (101) and used to evaporate a second working substance, and a first condenser (102) respectively connected to the secondary evaporator (20) and the primary evaporator (10). The secondary ORC power generator assembly comprises a secondary evaporator (20), a secondary power generator (201) connected to the secondary evaporator (20), and a secondary condenser (202) respectively connected to the secondary evaporator (20) and the secondary power generator (201). The system further comprises a generator (30) used to concentrate a third working substance, a third condenser (301), and an absorber (302).
