Beschreibung
Zusammenfassung:	The invention discloses a gas power generation combined two-stage shunting Rankine cycle system and a power generation method thereof. The system comprises a high-temperature Rankine cycle device, a low-temperature shunting organic Rankine cycle device, a heat source and an auxiliary device of the heat source, the working medium outlet end of the preheater is connected with a three-way regulating valve, so that the working medium is divided into two paths for evaporation and heat exchange, and meanwhile, the regulating valve can flexibly regulate the working medium shunting proportion when the working condition changes, so that the system output power and stability are improved; a cylinder sleeve water three-way adjusting valve is arranged at a cylinder sleeve water outlet of the preheater and can adjust the shunt volume of cylinder sleeve water entering a cooling water major cycle so as to ensure that the water temperature of a cylinder sleeve water inlet meets the requirements of a gas generator set when wo
