Time duration t'<SB>f</SB>from failure generation to P<SB>sc</SB>=P<SB>ss</SB>(output characteristics to variation of rotor angular velocity=asynchronous induction generator output power in a steady state) is computed by using output power-gliding properties expression (12) of the generator. By using expressions (13), (14), energy A<SB>ac</SB>which is added to the generator in failure period and accelerates a rotor, and energy A<SB>de</SB>which reduces generator speed after reconnection, are computed. A<SB>ac</SB>=A<SB>de</SB>is solved, and stability limit reconnection time duration t'<SB>cr</SB>is obtained. The stability limit reconnection time duration of the asynchronous induction generator can be computed by using the above method, without needing numerical integration, etc. from a stability limit expression based on an equal area method.  <P>COPYRIGHT: (C)2004,JPO
