An adjustable speed flywheel generator (FWG) can control both active power and reactive power rapidly. We have studied effect of FWG installation to a large-capacity and long-distance transmission system, especially when the system includes loops. In this paper, we describe the selection of FWG location, the selection of stabilizing control input signal, and the required quantities of FWG. FWG location is selected by a PQ-Sensitivity method, which is simple and easy to estimate the effect of both FWG's active and reactive power. As a stabilizing control input signal, we use bus voltage frequency instead of power flow because the flow changes stepwise by opening three-phase single-circuit. Additionally we clarify the required FWG quantities to design, such as FWG's active power and reactive power. We considered FWG's slip to determine the quantity because the capacity of the exciter depends on slip.
