Abstract

With increasing trends of non-linear and reactive loads even in Micro Hydro Power (MHP) Scheme, problems due to harmonic current and reactive power balance is increasing. The conventional Electronic Load Controller (ELC) for speed control does not take care of effect of un-balanced consumers load. The conventional ELC consumes some reactive power due to delayed chopping of waveform of current through ballast load of ELC. This paper proposes an advanced Electronic Universal Controller which takes care of frequency control, reactive power balance and voltage control, harmonic current compensation and unbalanced load compensation by a single compensator. The proposed system operates on the basis of instantaneous P-Q theory by which the harmonics and neutral current is suppressed and further the outer control scheme is applied for the frequency balance and reactive power compensation.
