N2 - We investigated the influence of a resistive type (R-type) and inductive type (L-type) fault current limiter (FCL) on the behaviour of the shaft torsional torque of a synchronous generator installed in a consumer system connected to a utility distribution system. In the case that the generator has relatively low natural oscillation frequency f0 under about 40 Hz, the L-type FCL suppresses the maximum value of the shaft torsional torque τsm to lower level than the R-type FCL. The R-type FCL with low limiting resistance may instead increase τsm under the condition of low f0. On the other hand, for higher f0, R-type FCL limits τsm at any limiting resistance as well as L-type FCL. The limiting effect of R-type FCL on τsm is larger than that of L-type FCL.
