This paper describes the rotor angle stability analysis of a distributed generators connected to a 10 kv distribution network consisting of wind generators, microturbines, and CHP plants. The distribution network being modeled in Matlab/Simulink/Sim Power-system takes into account detailed dynamic models of the generators. Fault simulations at various locations are investigated. For the studied cases, the critical clearing times are calculated and the influence of the inertia on the CCT of DG’s is analyzed. Results obtained from several case studies are presented and discussed.


Key words: Distributed resources, distribution system, dynamic modeling, critical clearing time, rotor angle stability, power system protection.
