Solar/air turbine generator system

A solar/air turbine generator system comprising:

• a compressor for drawing in and compressing air;
• a solar receiver for heating the air compressed by the compressor with the use of solar heat collected by a solar collector;
• an air turbine for driving the compressor and a generator by receiving the compressed air heated by the solar receiver;
• a regenerative heat exchanger, located downstream of the compressor and upstream of the solar receiver, for heating the air compressed by the compressor using the exhaust of the air turbine as a heating medium;
• a distribution device, located downstream of the compressor and upstream of the regenerative heat exchanger, for distributing the air compressed by the compressor to the side of the regenerative heat exchanger and to a bypass side, the bypass side being the inlet side of the air turbine;
• an air cooler for cooling the air drawn in by the compressor;
• a coolant circulating pump for circulating cooling water to the air cooler;
• a centrifugal chiller for cooling the cooling water;
• an adjusting valve for controlling a flow rate of the cooling water flowing to the air cooler;
• an air cooler outlet air temperature controller for controlling an opening degree of the adjusting valve;
• a first temperature sensor for detecting an air temperature at an inlet of the air turbine;
• a second temperature sensor for detecting an air temperature at an outlet of the air cooler;
• and
• a third temperature sensor for detecting ambient temperature,
• wherein the solar/air turbine generator system further includes a control device for maintaining the air temperature at the inlet of the air turbine at a constant value by adjusting the flow rate of the air turbine exhaust that flows into the regenerative heat exchanger as a heating medium, and
• wherein the air cooler outlet air temperature controller reads the air turbine inlet air temperature detected by the first temperature sensor, the air cooler outlet air temperature detected by the second temperature sensor, and the ambient temperature detected by the third temperature sensor to control the air cooler outlet air temperature such that the air turbine inlet air temperature is maintained at a constant value.
