Abstract

Electrical power distribution has risks that cannot be avoided, namely short circuit disturbances, both symmetrical and asymmetrical, temporary or permanent. Electricity providers' efforts to avoid or localize disturbances use protection systems, one of which is the Over Current Relay (OCR). The use of OCR in electric power transmission or distribution networks requires careful current and time settings according to the characteristics of the fault and the location of the fault. As an effort to facilitate operators and academics in the process of understanding and providing learning media or training to be able to simulate the current and time settings of OCR in securing the electric power transmission/distribution network, an OCR setting simulator of the electric power transmission or distribution network system is needed. built electronically using a microcontroller. The simulator built represents a three-phase electrical network with treatment of single-phase, inter-phase and three-phase faults. In each type of short circuit treatment, the fault current that occurs in section I (upstream) is greater than the fault current that occurs downstream, namely section II and section III. The working time of the relay in each section is faster at greater fault current values ​​which are influenced by the variable TMS (Time Multiple Setting) and setting current (IS) values

Abstract

The tool is designed to ensure that solar panels are always positioned perpendicular to the sun using an Arduino Uno as an automatic controller, along with other components such as light sensors (LDR) and DC motors. This microcontroller operates by processing data from the LDR sensors using programming on the Arduino Uno. When the LDR sensor is not aligned with the sun, its resistance value will differ. If this difference occurs, the microcontroller will move the motor to adjust the solar panel until the resistance returns to an equal value. The data logger monitoring aims to track the power capacity of the solar panels. Arduino is capable of generating optimal voltage when the solar panel is perpendicular to the direction of the sun. Based on tests conducted by comparing static solar panels with solar panels equipped with dual-axis trackers, it was found that solar panels with dual-axis trackers have a more optimal solar energy absorption capability. This is evident from the measurement of the electrical voltage generated, where the voltage on solar panels with dual-axis trackers is higher compared to static solar panels or those using single-axis trackers. The data obtained shows an increase in voltage starting at 09:00, with the maximum voltage recorded at 13:00, before eventually declining. The Data Logger can be monitored using the Blynk application, allowing it to be tracked through the Internet of Things (IoT).
