Abstract

Power-electronics based Compact Fluorescent Lamps (CFLs) have been proven to reduce electrical energy consumption for lighting purpose. As in common power-electronics-based electrical devices, CFLs can be categorized as non-linear loads. Therefore, the input current has a non-sinusoidal waveform and contains harmonics. This paper discusses the advantages and disadvantages of CFL application and proposes the attachment of THD value to the product package in order to improve the marketing policy. Total Harmonic Distortion (THD) is a method used to find the percentage value between the total harmonic components and their fundamental components. The percentage of THD causes the greater risk of damage to equipment due to harmonics that occur in current and voltage. Laboratory testing shows that a CFL sample has THD of the input current as high as 67.7%. This THD is relatively high and may degrade the electrical power quality. Moreover, it could lead to the misreading of electrical power and energy meter. Several experiment results are shown and analyzed to confirm the validity of the discussed matter.

Abstract

This paper discusses the design of a passive filter system for energy saving in Energy Saving Lamps (LHE) and Light Emitting Diode (LED), but for LHE and LED lamps for current Total Harmonic Distortion (THDi) that do not meet the standard. To reduce the current THD, it can be done by installing a single tune passive filter.””In this paper, we discuss the design of” a”passive filter system using a filter design with Matlab Simulink to determine the size of the components in filter design. To reduce the level of current harmonics, a single tune passive filter is designed which consists of an inductor and capacitor (LC) on the LHE and the LED.”Based on the research”data”that has been carried out,”the THDi measurement results for the lamp load test after using the filter are 49.12% for the LED circuit, 41.86% for the LHE circuit and 11.59% for the combined LED and LHE circuit.”Based on the results”of”each”measurement,”it can be seen that none have met the IEEE 519- 2014 standards. In this study, only using a filter tuned to the 3rd order, and based on the simulation results, it meets the IEEE 519-2014 standard, which is 1.11%.”The results of the design and testing of”tools (filters) show that they do not meet the IEEE 519-2014 standards, namely 11.59%.

Abstract

Requirements of energy in nowadays are directly proportional with human activities which use a lot of energy, especially for electrical energy, therefore, it is necessary to take energy saving measures such as lighting that use electronic devices with energy efficient. The latest lighting technology is used saving energy lamp (LHE) and light emitting diode (LED) which are designed to replace that use of incandescent lamps. The purpose of this research was to compare lamp based on light flux, colour temperature total harmonic distortion (THD) and power factor. The standard used for luminous lighting flux, the colour temperature standard of SNI 03-6575-2001 and THD using reference IEEE 519-2014.From the study has been done is obtained that level of lighting flux produced by LED type is bigger for twice than LHE type. The best colour temperature is LED with ratio value of 875oK/W. THD current for LHE and LED does not comply the standard, therefore THD current is smaller 4% - 7,3% from LED. The power’s factor produced by LHE and LED is 0.5 to 0.6.

Abstract

Abstract. Along with the rapid development of power electronics technology which is also useful for saving electrical energy. This technology is also used in lighting such as energy saving lamps (LHE) and light-emitting diode (LED). However, LHE and LED are non-linear loads that cause electrical power quality problems, namely producing voltage and current waveforms that are no longer sinusoidal or distorted waveforms. Distorted waves cause harmonic waves which have a frequency multiple of the fundamental frequency. The sum of the effective values of the harmonic components of the distorted waveform is calculated in terms of total harmonic distortion (THD). This study found that the THD value of the voltage generated by the LHE and LED loads was equal is 0.80% -1.3%, while the current THD generated by the LHE load was 68.57% - 78.68% and the LED was 72, 15% - 86.04%. The current THD value generated by the LHE and LED loads does not fulfil the IEEE Std 519-2014 harmornic distortion limits. The use of LHE and LED lamps simultaneously will reduce the resulting current THD value by 3% to 9%.

Abstract

This paper discusess the calculation of solar photovoltaic energy using a probabilistic approach in Nias and Mentawai districts. The application used is the @RISK Risk Analysis Project Model. In this research, the calculated random variable is the average temperature, the length of sunshine per month and solar radiation according to the regional zone. These three variables are fluctuating, so that the approach of each varianble uses a uniform distirbution function. From the three variables, it can be calculated that the energy generated by solar photovoltaic with a capacity of 100 Wp in Nias Regency is 21.062,57 kWh in one year with a probability of 55% and a capacity factor of 24,04%. Meanwhile, in Mentawai District, the same solar photovoltaic capacity of 100 Wp produces 19.249,47 kWh of energy with a probability of 50% and a capacity factor of 21,97%. From the results of this study it can be seen that the average temperature, duration of solar radiation and solar radiation can determine the electrical energy that can be generated by solar radiation can determine the electrical energy that can be generated by solar photovoltaic

Abstract

This paper discusses the design and construction of a solar powered generation system (PVs) in a 3-storey office building in the Bintaro area. The paper discusses the costs to build PVs, as well as an analysis of the value of investments using RETScreen Expert software. The calculation to get the PVs capacity is based on the area of ​​the roof and the electricity load of the office. This PV system will be integrated with the PLN electricity network in serving electricity loads in offices on each floor. The type of PV module has 305Wp capacity per module. The investment value is simulated with the assumption that battery units are replacemed every 3 years, repayment of the loan for 10 years with an advance of 50%, an interest rate of 5.75% and inflation of 3.28%. From the simulation we also obtained a comparison of investments between replacing the battery units once every 3 years with every 10 years, which became the basis for the decision of the PLTS owner to determine the scheme to be choiced.

Abstract

Based on the location of Indonesian astronomy which is located on the equator, it is very appropriate or feasible if Indonesia develops PLTS as a technology to offset human demands for dependence on electricity. Indonesia also has a tropical climate (consisting of 2 seasons, hot and rainy), so that solar radiation in the territory of Indonesia (± 12 hours) is sufficient to make PLTS a solution for the demands of electricity needs. One of the technologies used in PLTS is solar panels. Solar panels are able to convert sunlight into electricity directly. The performance of solar panels is influenced by several factors, namely solar radiation, temperature and wind speed. Calculations and analysis of the measurement results show that the performance quality of solar cells is not very good, namely 0.143 for solar cells without reflectors, 0.156 for solar cells with galvalume roof reflectors and 0.157 for solar cells with aluminum foil reflectors. And the efficiency of solar cells without reflectors is 7.48%, for solar cells with galvalume roofs is 8.75%, and for solar cells with aluminum foil is 9.72%
