Battery-less Power Conditioning System using Mechanical Fly WheelBattery-less Power Conditioning System using Mechanical Fly Wheel

Abstract

Considering the abundant sunlight so as the insolation available over many months in the Indian sub-continent, renewable energy can be easily harvested using solar photovoltaic array to supplement the grid power. This work proposes such an arrangement through a battery less UPS system. The need for battery less UPS system arises since batteries used in the conventional UPS system have less life time and a major concern of environmental pollution. Considering a premises/ organization where there is a power back up facility like a diesel generator, the role of batteries in the UPS system is limited and used for only few seconds between the mains power failure and the turning on of generator. Hence for such short term power requirements, a Kinetic Energy based medium for storage such as fly-wheel based energy storage can be effectively utilized instead of the electrochemical batteries. Hence the combination of solar PV based power generation along with a battery less online power conditioning system to supply a critical load is the proposed in this scheme.
