Abstract

In the electrical energy distribution system, power distribution systems, especially in the SUTM network, SKTM, and 20 kV distribution substations, can experience various obstacles that stop the distribution of electrical energy to consumers. In addition, various disturbances also cause damage to electrical equipment. One way to minimize or minimize the outage area and damage to various components that are electrified due to interference, a protection system is needed. More specifically, in avoiding the duration (SAIDI) and frequency (SAIFI) of customer outages, it is necessary to set the protection relay properly as a form of protection or protection so as to minimize the position and place of interference. Coordination of the protection system pattern of a network is said to be good if it can minimize the number of outages as small as possible based on the distance and location of the disturbance. After calculating the protection coordination system with ETAP simulation. In the ETAP simulation, the sequence of protection coordination has run well and the protection works in the correct order according to the calculation settings that have been input. The advantage of good protection system coordination is that if there is a disturbance at one point of the distribution network, it does not interfere with the production process in other distribution networks so that the number of outages can be reduced and the affected area can be localized as small as possible. The results of the coordination of the installed protection system on the distribution network utilizing ETAP can be seen that the existing OCR and GFR settings are still not good, for example, if there is a disturbance in the LH 04 feeder network, the relay sequence that releases the contact is LH 03, causing many customers to go out that should not be included. resetting OCR and GFR protection on the distribution network can be based on the fault current that occurs along the network. Overcurrent disturbances are used for low setting and high setting on OCR and GFR protection, for curve characteristics using inverse time standards combined with instantaneous relays. By resetting the OCR and GFR on the distribution network, the reliability of the protection system coordination and the selectivity of the protection sequence are better than the existing conditions so as to create an ideal protection system coordination.

Abstract

This paper analysed the reliability of the 20 kV distribution system at PT. PLN ULP Tanjung-balai. The reliability of the electricity distribution system is crucial to ensure a stable power supply with minimal interruptions to consumers. The study aims to identify and evaluate the factors affecting the reliability of the 20 kV distribution network and propose solutions to enhance the system's reliability. The methods used in this study include the collection of historical outage data, analysis of network performance, and calculation of reliability indices such as SAIDI (System Average Interruption Duration Index), SAIFI (System Average Interruption Frequency Index), and CAIDI (Customer Average Interruption Duration Index). Additionally, the study utilizes network analysis software to simulate the operational conditions of the distribution network. The results of the study indicate that the reliability of the distribution system at PT. PLN ULP Tanjungbalai requires improvement, particularly in reducing the frequency and duration of power outages. Several identified causes of outages include extreme weather conditions, equipment failures, and external factors such as animals or vegetation. To improve system reliability, several actions are recommended, such as more intensive preventive maintenance, modernization of distribution equipment, and enhanced monitoring of the distribution network.

Abstract

The increasing demand for electricity and the efforts to reduce the environmental impact of waste drive the development of biomass-based power plants. This research analyzes the potential of utilizing waste as raw material for biomass briquettes to generate electricity. The waste used consists of organic materials processed into briquettes with specific characteristics, such as moisture content, calorific value, and density, to optimize combustion. The study was conducted as a case study on a small-scale biomass-based power plant. An analysis results show that waste briquettes have significant potential as a renewable energy source with relatively high conversion efficiency. Utilizing waste briquettes not only reduces the volume of waste sent to landfills but also lowers greenhouse gas emissions compared to fossil fuels. This study provides recommendations for improving briquette production technology and optimizing combustion systems to achieve better efficiency in biomass power plants.

Abstract

This study analyzes the reliability of the electrical and pneumatic monitoring system on the Boeing 737 aircraft, which is a critical component in ensuring the safety and operational efficiency of the aircraft. The electrical system is responsible for supporting various vital functions of the aircraft, such as navigation, communication, and flight control, while the pneumatic system regulates airflow for various subsystems, including the anti-icing system, cabin control, and hydraulic pressure. The purpose of this study is to evaluate the performance of the monitoring system in detecting disturbances or failures in electrical and pneumatic components. The approach used involves direct monitoring, historical data collection, and predictive analysis using statistical methods to assess the level of system reliability. The results of the study indicate that the Boeing 737 monitoring system has high reliability in detecting problems before they become critical, but there are several aspects that need improvement, especially in terms of early detection of failures in the pneumatic system. Improving the reliability of the monitoring system can be done through the integration of more sophisticated sensor technology and artificial intelligence (AI)-based predictive algorithms. Thus, these improvements can improve the operational safety and efficiency of the aircraft.
