Proposed Design of Micro-Hybrid Power Distributor as a Mini Power Station for San Pascual Senior High School 1

Abstract

INTRODUCTION

Hybrid systems are needed to achieve economic and ecologic targets while at the same time, ensuring an increasingly independent, decentralized, grid -connected power supply that industries, utilities, municipalities and private individuals are aiming for. Providing rural electrification programs, catering to the rural power requirement has been challenging due to technical, administrative, financial and management constraints. As such, this study aimed to create a hybrid power distributor which implements the two known efficient systems: solar and windmill distribution system. The said system will be installed at San Pascual Senior High School 1, San Pascual, Batangas where sunlight and wind power can be harnessed.

METHODS

The model included three (3) components; the description of the micro hybrid power distributor and the level of effectiveness of the two hybrid power generation systems; the researcher-made questionnaire; and the proposed design. The subjects of the study were the 30 students of EIM 12 Volt. From a total of48 students, 30 respondents were chosen by convenience sampling, under purposive sampling. The researcher used a self-constructed questionnaire as data gathering instrument. The statistical tools used which correspond to the research questions were frequency and weighted mean.

RESULTS

Data revealed that the design implemented a standalone micro-hybrid power distributor using solar photovoltaic and windmill power; consists of a horizontal axis wind turbine; with interconnected grid systems with battery as power bank; connected to AC/DC load; had a shifting of power distribution and had an optimum combination of solar PV-wind hybrid system that lie between 0.70 and 0.75 of solar energy to load ratio. in terms of its level of effectiveness, the respondents agree that the micro hybrid power distributor was eco-friendly and reliable in operation, requires low maintenance and has long lasting feature with 3.71 as its weighted mean.

DISCUSSIONS

The proposed design implemented a standalone micro hybrid power distributor with battery/power bank consisting of a vertical axis wind turbine and rotary PV modules with sensors. It is connected to AC/DC load only. It has a shift of power distribution since the solar panels can detect the light from the sun during the day and the light from the moon during the night. With the combination of these two renewable energy sources, the study was able to make the most efficient power distribution system that people can rely on.
