Solar thermal power generation system using single hot molten salt thermal energy storage tank

A solar thermal power generation system using a single hot molten salt thermal energy storage tank, the solar thermal power generation system comprising:

• a solar collector that collects solar heat and heats molten salt;
• a single thermal energy storage tank in which a plurality of unit blocks having a plurality of flow holes are stacked and combined such that the molten salt heated from the solar collector passes through the plurality of flow holes and the molten salt is stored in the plurality of unit blocks of the single thermal energy storage tank;
• a power generator that generates electricity by a steam generated from a circulation fluid by heat of the molten salt stored in the single thermal energy storage tank;
• a high temperature heat storage flow path on which high temperature molten salt heated in the solar collector is guided toward the single thermal energy storage tank;
• a low temperature heat storage flow path on which low temperature molten salt discharged after heat is stored in the single thermal energy storage tank, is guided toward the solar collector;
• a heat dissipation flow path which is diverged from the high temperature heat storage flow path and on which heat stored in the single thermal energy storage tank is absorbed and dissipated;
• and
• a heat exchanger that heat-exchanges the molten salt on the heat dissipation flow path with the circulation fluid discharged from the power generator to generate the steam from the circulation fluid.
