Steady-state temperature field of stator bar of double water internal cooling synchronous condenser

Abstract

Synchronous condenser is a key part of ensuring stable operation of the extra-high voltage AC and DC transmission grid. In order to optimize and ensure the reliable operation of the synchronous condenser cooling system, it is necessary to master the temperature distribution in the synchronous condenser. In the double water internal cooling synchronous condenser, the fluid flow and heat transfer are quite complicated in the water-cooling system of the stator and the rotor. In this paper, the steady-state temperature field of stator coil of TTS-300-2 300MVar double water internal cooling synchronous condenser is calculated by using the finite volume method. The influence of empirical parameters on the calculation results is reduced. The calculation results show that the water temperature and copper temperature increase linearly along the direction of water flow.
