Embodiment 1
[0026] see figure 1 , the present invention discloses a geothermal wellhead power station system, said geothermal wellhead power station system includes: a second gas-liquid separator 1, a flash tank 2, a second steam screw expander 3, a second generator 4, and a steam ORC system . The second screw expander 3 is connected to a second generator 4 .
[0027] The steam ORC system includes a first evaporator 11, a first preheater 12, a first working fluid delivery mechanism 13, a first condenser 14, a first steam screw expander 15, a first generator 16, a first gas Liquid separator 17; the first condenser 14 can be an air-cooled condenser, a water-cooled condenser or an evaporative condenser.
[0028] The first end of the second gas-liquid separator 1 is connected to the second steam screw expander 3, the second end is connected to the flash tank 2, the saturated steam enters the second steam screw expander 3, and the high-temperature and high-pressure brine enters the flash tan...
Embodiment 2
[0035] The difference between this embodiment and Embodiment 1 is that in this embodiment, the working medium delivery mechanism is a combined working medium pump, and the combined working medium pump includes at least one variable frequency pump and at least one fixed frequency pump. Each variable frequency pump, Fixed frequency pumps are connected in parallel.
[0036] In the heat engine stage, start-up stage and partial load conditions, only use variable frequency pumps, or use a combination of part or all variable frequency pumps and part or all fixed frequency pumps; in full load conditions, use variable frequency pumps and fixed frequency pumps The pumps are all on.
[0037] At the same time, the system also includes a second working condition automatic identification module, a second demand calculation module, and a second switching module.
[0038] The second working condition automatic identification module is used to identify the working condition of the system, and...
Embodiment 3
[0043] The difference between this embodiment and Embodiment 1 is that in this embodiment, the condenser is a combined condenser, and the combined condenser includes at least one air-cooled condenser and at least one evaporative condenser, and each air-cooled condenser , Evaporative condensers connected in parallel.
[0044] When the ambient temperature is higher than the first set temperature, the evaporative condenser plays a major role in reducing the condensation temperature of the system. When the ambient temperature is lower than the second set temperature, the air-cooled condenser plays a major role in reducing the condensation temperature of the system.
[0045] In addition, the system further includes a second working condition automatic identification module, a second demand calculation module, and a second switching module.
[0046] The second working condition automatic identification module is used to identify the working condition of the system and judge whether...
