Development of Advanced Power System Analogue Simulator

IEEJ Transactions on Power and Energy, 1990
AbstractThe digital simulation method has been utilized to analyze phenomena in power systems. Since different algorithms can be applied, depending on the phenomena to be analyzed, digital simulation allows for high‐precision analysis.However, it also has a disadvantage: it produces continuous phenomena which occur in actual systems only fragmentarily.
