Abstract

Background/Objectives: Objective of study is discussing about the harmonic effect on electrical apparatus as well as its mitigation methods. Then power quality analysis is performed to four textile and one coffee rural industries. Methods/Statistical Analysis: The power quality analysis is performed by using Clamp on Power meter. It is measured voltage, load current, power component variations and total harmonic distortion on industries. The measurement was carried out at supply fed end. Findings: Review shows, the growth of electronic components on power system causes harmonic distortion. Although, rapid capacity addition of renewable energy resources on the conventional grid injecting harmonic distortion on electrical networking. These power quality issues are reduced life span of electrical utilities. Hence, these power quality issues are rectified by suitable compensating devices. The total harmonic distortion on textile industries is much higher that of the coffee industry. Since textile industry is used variable speed drives, whereas content speed motors are used in the coffee industry. Also voltage swell is occurs on all industry but it within limit. The harmonic suppressing technique is needed in present day trend. In addition, Load management system in a textile industry is poor. So reforms the load management systems in industries is also recommended. Applications/Improvements: Textile industry and Coffee industry.

Abstract

Background/Objectives: This paper reviews the performance and emission characteristics of C.I. engine fueled with preheated vegetable oil. Methods/Statistical Analysis: Vegetable oils can be a good alternative source for fossil fuel. The engines available in the market are designed for petroleum diesel which found to be less efficient while using vegetable oil as fuel. The main problem in the usage of vegetable oils in C.I. engine is their high viscosity and low calorific value. The viscosity is reduced by methods such as transesterification, blending of vegetable oil with diesel, preheating the vegetable oil. Only few authors had done experiment with preheated vegetable oil in C.I. engine. Findings: From the result and output given by the authors the review is done. The results are favor for preheated vegetable oil than unheated vegetable oil. In all the cases BTE of preheated vegetable oil is higher than unheated vegetable oil. Most authors said that BSEC of preheated vegetable oil is almost equal to diesel and lesser than unheated vegetable oil. It was found that HC and CO emission for preheated vegetable oil is lesser than unheated vegetable oil, were NO_x is found to be higher for preheated vegetable oil. CO₂ emission while using preheated vegetable oil is higher than unheated vegetable oil and diesel. The usage of vegetable oil neutralizes CO₂ emission, so there will not be any new CO₂ emission into the atmosphere. Preheated vegetable oil is a promising alternate for mineral diesel. Applications/Improvements: Long term usage of preheated vegetable oil may affect the lubrication oil and fuel line so change in rescheduling of replacing the lubrication oil is needed. Pongamia oil, neem oil and jatropha oil are found to be reliable alternative fuels. Combined effect of preheated and blending of vegetable oil as an alternative fuel for diesel engine would give best result in performance and emission wise.
