要約(英語): This paper proposes a reduction method of subtransmission system including various distributed generators (DG) mainly for the efficient transient stability studies. The proposed method is based on the concept of expressing the original branch impedances consisting of the reduced system as equivalent branch impedance. The reduced system consists of two nodes and two branches with two equivalent impedance, those are obtained respectively for loads and DG's of the original system. Each node in the reduced system represents either load or DG, and both the value of two reduced branch impedance can be kept in the reasonable positive range. The reduction system is configured so that the operating condition at boundary node after reduction is matched to that of the original network, also the DG terminal voltage magnitude at the reduced system is maintained as the average DG voltage magnitude in the original system. Demonstrative result to the application in the transient stability simulation is presented in order to verify the practicability of the proposed method.
