Abstract:
With the gradually wide application of short circuit current limiter，although the power transmission capability of power transmission system is continuously growing，the upgrading of the short circuit capacity of the transmission system is not obvious because of the introduction of short circuit current limiter in power system. This paper bases its theories on conditions that the short circuit current limiter is inserted into single machine infinite power system and that the transmission line is short-circuit. And this paper mainly studies influences on output power which are caused by the variation of equivalent circuit of the system previously referred，its impedance value and the impedance of output line. This paper also studies influences on rotational speed and angle，torque-angle curve and working stability of infinite power busbar system of the generator and problems on active loss of short circuit current limiter itself when the system is short-circuit and the short circuit current limiter is impedance pure inductance and R-L typed impedance.
