2導体法による架空送電線のギャロッピングシミュレーション計算

抄録

An instantaneous power failure due to a galloping have a great influence on power consumers, so studies on a galloping have been done even today. Our study differs from other ones on the points that non linear three dimentional simultaneous equations of conductor movement can be solved directly using numerical calculation and simulations can be performed easily. In this paper, firstly, we explain the double conductor method which strictly deals with boundary conditions at the point where an inter-phase spacer is attached. Then, fundamental characteristics are made clear through simulations. These results showed the effectiveness of our method. And also the numerical calculation in case of an inter-phase spacer attaching are developed. Simulation results showed that a clearance between phases can be maintained even in severe conditions.
