In this study the effect of MOSA on controlling of the non-conventional ferroresonance overvoltage
in the iron core voltage transformer is studied. It is expected that MOSA can generally damp ferroresonance
overvoltages. Time-domain study is used to analyze this effect. Study is done on a voltage transformer rated
100VA, 275 kV. The magnetization characteristic of the transformer coil is modeled by a single-parameter twoterm
polynomial with q = 7 degree of nonlinearity. Core loss is modeled by linear resistance. Simulation results
show that connecting the MOSA in parallel to the voltage transformer, shows a great controlling effect of the
ferroresonance oscillations. Phase plane, time domain voltage waveforms, FFT analysis and bifurcation
diagrams are also given. Significant effect on settling down to the chaos, the range of parameter values that may
lead to ferroresonance overvoltages and controlling these phenomena are obtained and presented.
Key words: MOSA , Chaos Control, Bifurcation Diagram, Ferroresonance oscillation, Voltage Transformers, ,
