Abstract

With the rapid development of hydropower, the fault of roto winding inter-turn short circuit of large hydro generator set is more and more obvious. We did the research of fault mechanism of turn to turn short circuit of rotor winding of hydro generator, and concerned the condition of saturation of the generator. After a series of deductions, we obtain the following criteria, (I_fc-I_f0)/I_f0 > %. In the formula, % general take 1%~2%. In the actual working conditions, using the formula to calculate the normal operation of the excitation current, compared with the actual measured value, if the deviation is large, it can be determined whether the turn to turn short circuit
