Abstract

Utilizing the Solar Home System requires a battery as an energy storage medium produced from photovoltaic modules. Today's batteries are lead-carbon Valve Regulated Lead Acid (VRLA) batteries. This type of battery has a 90-95% round-trip efficiency and a deep discharge (DOD) level of 80%. This type of battery is not environmentally friendly because it produces lead acid. Therefore, the development of batteries in the SHS system from lithium battery technology is carried out. Besides being environmentally friendly, its round-trip efficiency is quite good compared to lead-carbon, which is 92-96% with a DOD level of 100%. In this study, it is proposed to apply lithium batteries on a lab scale so that they can assist students in developing scientific fields, especially lithium battery-based energy storage. In addition, this research will describe the process of making and prototyping lithium batteries in solar practicum learning media. From the test results obtained, a laboratory-scale Solar Home System prototype for solar power system practicum using Lithium batteries as Energy Storage. The average effect of charging the battery is 21.09 watts. With the highest battery charging voltage set at 14.08 Vdc. And the highest charging current rate is 1.37 A, with the highest battery charging efficiency rate of 12%. The characteristics of the Lithium battery itself, the DoD shown is also good when the capacity read on the battery meter is 0%. The battery can still supply 15 watts of load for 20 minutes

Abstract

Prediction of electrical load on 150 kV Sulselrabar electrical system, analyzed using approach at night peak load using Fuzzy Logic based intelligent method. The peak load characteristics are certainly different from the load in normal time, therefore a special approach is needed to predict the peak night load. As input data will be used data of night peak load in 2010 until 2015, on the same day and date, each 4 days before day-H or day date which will be predicted load. For the data processing stage is divided into several stages, namely pre-processing, processing, and post-processing. The load data processing follows several procedures, ie computing WDmax, LDmax, TLDmax and VLDmax each year. Data processing is processed using excel software and then using Matlab software to run Fuzzy Logic. From the analysis results obtained, Error Prediction The peak evening load is very small that is equal to -0.070033687%. As comparison data used actual day-H data is April 2016. The graph of analysis result also shown in this paper.Keywords– Fuzzy Logic Control, Load Forecasting, Error, VLDmax

Abstract

A 20 kV cubicle is a set of electrical equipment installed in a distribution substation as a distributor, circuit breaker, connector, controller, and protection system for the 20 kV voltage power distribution. The frequent issue in these cubicles is corona discharge on electrical equipment, which is a phenomenon occurring when the air around conductors or conductive materials becomes ionized, resulting in the release of charges that can lead to insulation failure in the equipment. The consequences are severe as it can damage the equipment inside the cubicle and cause power losses. This research analyzes the influence of humidity, temperature, sound, and light conditions inside the cubicle to identify the symptoms of corona discharge in the 20 kV cubicle and its accessories. The goal is to create a tool that can address and anticipate the issues related to corona discharge caused by the effects of humidity, temperature, sound, and light.
