In this thesis, we take the delay r as a bifurcation parameter to investigate the Hopf bifurcation phenomenon in system (1). By analyzing the associated characteristic transcendental equation of system (2), and using the Hopf bifurcation theorem, we obtain one condition for the existence of Hopf bifurcation in system (1).

This article introduces the selection of relative reactor value of filter X% and its relation to external performance of filter. The selection among parallel capacitor, dissonances filter and assonance filter based on the environment are discussed deeply. The relation between filter parameter and engineering design are once more discussed. Finally, how to coordinate the functions of harmonics and reactive power compensation is argued.
