Abstract: With the development of renewable energy technologies,the small or micro distributed generators（DGs） are embedded in distribution network,and the transient stability problem might occur in the distribution network.The squirrel-cage rotor induction generators（IGs） are widely applied in distribution networks due to lower unit cost,smaller size,and less maintenance requirements.The transient stability problem in distribution networks with multi IGs was analyzed,and the transient stability region and critical clearing time（CCT） were defined based on the theory of an IG.Considering the constraint of network equation and rotor speed variations of IGs,an analytical method based the steady-state equivalent circuits of IGs to determine the transient stability of distribution network with multiple IGs is proposed.And the critical speed and CCT of distribution network are calculated using the proposed method.Compared with dynamic simulation,the analytical method has smaller computation and could reveal the interaction of multi IGs for transient stability analysis.The correctness of the proposed method was verified by the dynamic simulation of the fifth-order model of induction generators in PSCAD/EMTDC simulation software.The reason that the calculation results using the steady-state equivalent circuits are smaller than the simulation results was analyzed.
