Simulation Test and Research on Evaporative Cooling of Hydraulic Generator for TGP Underground Power Plant

摘要

This paper describes the development and appliance of the evaporative cooling simulation platform of ThreeGorges Underground Plant Generator, based on which, a series of full simulation experiments were taken out, to acquire the characteristics of the temperature rise versus generator load, liquid pressure, liquid level and secondary cooling water flow rate, etc. Then a reasonable setting of the evaporative media level, flow rate and pressure is proposed, which will determine the cooling system scheme design, as well as the specifications of the employed condenser, pipe adapter connector, and cutting ferrules, to guarantee the reliability of the evaporative cooling system of Three-Gorges Underground Plant Generators.
