Constant Temperature Control of Solar Thermal Power Plant at Transient Variation of Sunlight

The constant temperature control is required for the steady output of photo thermal generator of a solar thermal power plant in the case of transient mutation of sun light . The potential risk incurred by the conventional photo thermal control system based on the temperature dependent flux control is thoroughly explored, with a proposition of a system control technique based on the law of energy conservation for the project. We present in the research that the critical factor for keeping constant temperature during photo thermal conversion is to ensure the equilibrium between input and output energy all the time between different parts of photo thermal conversion. The idea is implemented by the sun light dependent flux control. This research provides solution for overcoming the damage to susceptible system because of the transient mutation of sun light.
