Focusing on control that can be used to efficiently regulate SMES, unique control logics for power system stabilization were devised by combining the popularly used power deviation (ΔP) of a generator with the angular velocity deviation (Δω) of a generator or the phase correction. In the previous paper, we analyzed the performance and characteristics of the new control logics (ΔP + Δω control logic, ΔP + Δω + phase correction control logic) on both one-and multi-machine infinite-bus systems using the Y-method power system dynamics analysis program, and suggested that the new logics could improve the stability of power systems in comparison to the conventional ΔP control logic.For the next phase of research, we have evaluated the performance and characteristics of the control logics mentioned above based on analogue simulation. As a result, the logics have showed the same tendency as the case of the digital simulation and it have been confirmed that the logics, especially ΔP + Δω+ phase correction control logic, have the superior effect on the improvement of the stability of power system.
