Abstract

Analysis of the level reliability in this study using section technique methods compared with ETAP software. Objectives to be presented in this study provide information about reliability of the Teluk Lembu substation PT. PLN Pekanbaru. By dividing the distribution networks based methods of calculating level of reliability section technique, which impacts the perceived failure of the same componet if the occurrence of the disoders that cause system outages. Step by step execution of this study include collecting data, performing calculations failure parameter, calculating the reliability index SAIDI (System Average Interruption Duration Index) and SAIFI (System Average Interruption Frequency Index). The calculate result obtained by using section technique method SAIFI = 1,745 time/hour, SAIDI = 5,34 hour/year, and CAIDI = 3,06 hour/year. With exiting standard in Indonesia as SPLN 68-2 : 1986 has values SAIFI (System Average Frequency Duration Index) is 3,2 time/hour and SAIDI (System Average Interruption Duration Index) is 21 hour/year, the index reliabilty of the distribution Feeder Surian still in the category reliable.Keywords: Section Technique, reliability, distribution system

Abstract

Reability evaluation has purposed to find out the level of reliability in distribution system. This research conducted at 20 kV radial distribution system in Bangkinang Substation with FMEA (Failure Mode Effect Analysis). The reability calculation will be compared to PT PLN Standart procedure and its target to be WCS (World Class Service). The reability index are used SAIFI (System Average Interruption Frequency Index) and SAIDI (System Average Interruption Duration Index). The method is gathering the data, data proccessing, and analysis. The SAIFI of four feeders in Bangkinang Substation has not reached the PLN standart 68-2 : 1986 which is 3,2 times/years/costumer. For SAIDI that already reached the requirement is 21 hours/years/costumer only Candika Feeder, Pahlawan, and Salo. While, PT PLN Target to get WCS (World Class Service) with 1.2 times/years/costumer for SAIFI and 0.83 hour/years/costumer for SAIDI, all of the feeder in Bangkinang substation still far from the target.Key words : distribution system, reability, FMEA, SAIFI, SAIDI

Abstract

The use of electric power is one of the basic needs around the world, but there are some areas or places that are also not reached by electricity, such as in coal waste fields that require pH sensing to measure the quality standard of waste before disposal. The use of photovoltaic systems is an alternative to solve this problem. In this study, tests and measurements were carried out to determine the ability of the photovoltaic system as a power source for pH sensing. Measurement and testing on the prototype is carried out by applying varying loads and covering the surface of the solar panel which results in a change in the value of voltage and current. Based on the results of solar panel testing by covering the solar surface (shading), when the weather is clear with radiation of 812.4 W / m2 and a temperature of 33.7° C, the solar panels will stop filling the battery by closing 90% while in cloudy weather conditions with radiation of 242.4 W / m2 and a temperature of 31.9° C, solar panels will stop filling the battery by closing 40%. Keywords: photovoltaic, pH sensing, load variation, shading

Abstract

Household electricity customer is a sector that contribute significantly to affect the high peak loads. This is because in this period people began to turn on the lights, television and other electrical equipment to run its activities which affects the availability of electrical energy. One effort that can be done on the condition that the limited electricity supply that is by saving electrical energy usage by implementing peak clipping and strategicconservation of reducing electricity consumption at times of peak load use power tools are more energy efficient. This research explores the benefits of the implementations of peak clipping and strategic conservation to changes in load pattern and the potency in energy savings. The analysis was focused on the household load of television in Pekanbaru. Based on the calculation and analysis, with application of peak clipping and strategic conservation on the television can increase daily load factor to 12,87%. The potency of energy savings is estimated at 43,99% per day of work.Keywords : load pattern, energy savings, peak clipping, strategic conservation

Abstract

Renewable energy is a natural energy source that can be directly utilized freely. In addition, the availability of renewable energy is unlimited and can be used continuously. One of them is by utilizing waste that can potentially be converted into electricity. So far in the Pekanbaru the waste has not been sterilized. It is only founded in the garbage dump of Muara Fajar. Pekanbaru has an area of 632.26 km², with a population reaching 1,064,566 people, every day being able to produce trash up to1,112 tons (density 0.3). By looking at the situation, it is necessary to do a proper analysis to determine the feasibility of building a power plant garbage power. The method used for calculating NPV and PP is the least cost method. From the results obtained the amount of electrical energy produced in a year 112592260.99 kWh / year, while the NPV value = Rp 80,061,249,724, and PP value 8 years. Lastly, the results of analysis given the construction of PLTSa in Pekanbaru fulfill the eligibility criteria to be based.. Keywords: energy, garbage dump, NPV, PLTSa, waste

Abstract

Transformer is a tool to transfer electricity power inter two or more electricity circuit through electro magnetic induction. Transformer consist of two parts, they are primary and secondary part, every part consist of several coils with the certain number and zise. In the making transformer, rolling process is made repeatedly in order to reach the standarized transformer criteria it took time and effort hardly to reduce this impact. It is needed a tool which can rool fastly and automaticly. This tool used 200Vac motor and 1350 RPM speed as the roller, so that it can reach the source electric power and fast speed for autoprocess. It uses ATMEGA8535 microcontroller as the main cycle where the microcontroller receive the number of coil through keypad interface. Microcontroller controls the roller motor by comparing the coils numbers which is entered by the coil numbers processed by the motor. The coil number detection processed by ten magnetic sensor through statical magnet which was available on the shaft of the motor. Comparatorchanges the sensor output voltage into digital pulses. This digital were counted by the microcontroller where every ten pulses equal one coils is same with the input number, it means the microcontroller shut down the motor.Keywords: Transformer, Motor, ATMEGA8535, Magnetic sensor, Comparator.
