Study on Outlet Temperature Control of External Receiver for Solar Power Tower

Due to the change of direct normal irradiance (DNI) and output power load, receiver solar tower is in an unstable state actual operation. In this paper, a 100 MW external cylindric designed modelled. The dynamic comprehensive model established for receiver, including thermal mechanical equations. temperature control strategy applied model. validity verified by disturbance experiments, DNI, inlet heat transfer fluid (HTF), weather data on cloudy day. response characteristics are demonstrated. Its lag restraining effect fluctuating environment revealed. dangerous occasion during operation detected, overheat local panel, dissociation point molten salt. Both robustness deficiency pointed out. research results will contribute formulation SPT (solar tower) station.
