Abstract


The Synchronous condenser is a commonly used device for power grid compensation. It plays an important role in the power system. In order to control the temperature rise in the winding within the allowable range, the water channel is blocked when the Synchronous condenser stator is cooled by water. Fault is one of the common faults, which affects the safe and reliable operation of the Synchronous condenser. In order to reduce the probability of fault occurrence, it is necessary to study the relationship between the degree of blockage of the wire rod and the temperature. In this paper, a 300Mvar Synchronous condenser is taken as the research object, and the distribution of the temperature field of the stator bars under different blocking degrees is studied.
