PHARMACEUTICAL INDUSTRIAL PLANT TRANSIENT AND POWER FACTOR IMPROVEMENT USING SPLIT-PHASE MACHINE

Abstract

Pharmaceutical industrial plant transient and power factor improvement using split-phase machine is presented. Pharmaceutical industrial plant study was carried out to examine transient stability and improve the power factor of the industrial plant so as to maintained quality services. This is because; stress on pharmaceutical industrial plant systems is increasing day by day, due to faults and sudden load change that constitutes negative threat to the industrial. Pharmaceutical industry are apothecaries that engage in wholesale, production of drugs such as morphine, quinine, and strychnine and companies that established research laboratory and discovered medical applications for their products. Electrical transients current is current before reaching steady state and are fast rise time, short duration energy pulses that have voltage and current components often transmitted down power lines. Power line transients are when AC/DC connections are made, broken, short circuit, that constitute negative threat to pharmaceutical industrial plant. Power factor improvements means generating reactive power and common methods are capacitor banks, synchronous condenser and phase advancer. A low power factor increased energy consumption, reduced efficiency, and additional costs. Split phase machine is a single-phase machine, with two windings, one provided with a starting winding, another with running winding and energized continuously. The alternating current circuit of pharmaceutical industrial plant contains pure reactance like capacitive or inductive voltage and current that is 90 degrees out of phase and in most cases no useful real power is developed. Laboratory investigating reveals that this was due to the fact that some reactance and the apparent power (VA) were greater than the real power (W). The difference between the real and apparent was caused by reactance known as reactive power (Var). The capacitance was connected across the machine load to reduce the transient line current and apparent power, the added capacitive reactance suppressed the transient line current to a minimum value thereby changed the real power consumed by the pharmaceutical machine. Transient and power factor improved drastically for smooth pharmaceutical industrial plant operation. The stator current decreases as power factor increases, the power factor peak at the stator current null point at 0.14 ampere, and at real power of 50 watts, the power factor is almost at unity (0.99) The experiment on the split-phase machine drives was performance and its various run-up characteristics results were presented graphically for dynamic study and this is recommended for technicians, operators, engineers and machines designers of pharmaceutical industries
