New BRM technique for space vector decomposition reactive power of SPIM

Abstract

This paper presents the methodology of Single Phase Induction Motor (SPIM) speed controlling by new Binary Rate Multipliers (BRM) technique that gives rise to suitable energy supply to motor at any instant. Knowing the voltage and current, power is calculated by vector space method. The result is feedback to Proportional - Integral (PI) controller for processing by means of BRM-which gives the patterns up to 256forms. It shows fast time response of returning to normal state, both loading and no load, not exceed 1.5 seconds. The superiority of this technique is that, both apparent and reactive power decrease while running at no load and full load power factor increase up to 0.444 and 0.633 respectively. Thus, higher efficiency is achieved.
