Abstract

This study proposes a hybrid method to classify and estimate the location of short circuit disturbance on power transmission lines. The hybrid method uses Discrete Wavelet Transform (DWT) and Adaptive Neuro-Fuzzy Inference System (ANFIS). The transmission system is implemented in a real system, in which the electric power transmission system on the KP bus to the GS bus is with a length of 64 Km. The DWT is used to process information from each phase voltage and current transient signal as well as the zero-sequence current for one cycle after the disturbance has started. The ANFIS classification is designed to detect disturbance on each phase and ground in determining the type of short circuit disturbance. ANFIS estimation is used to measure the location of disturbance that occur on the transmission line. The training and testing data are generated by simulating the types of short circuit disturbance using software with variations in disturbance location and fault resistance. The result is that the disturbance classification is with 100% accuracy and the estimated disturbance location is with the lowest error of 0.0006% and the highest error is 0.03%.

Abstract

ABSTRAKUntuk memastikan bahwa kebutuhan masyarakat yang berkembang terpenuhi dan tingkat ketergantungan sistem cukup, sangat penting untuk mengelola dan memelihara sistem distribusi daya yang andal. Karena jarak transmisi yang jauh, tidak mungkin untuk mencegah kerusakan instalasi pada sistem tenaga listrik. Hal ini berdampak signifikan pada transmisi tenaga listrik, yang mengakibatkan penurunan tegangan dan hilangnya energi listrik. Penggunaan Flexible Alternating Current Transmission System (FACTS) merupakan salah satu cara untuk mengurangi ketidakstabilan tegangan dan meningkatkan kehandalan jaringan tenaga listrik. Perangkat FACTS adalah Thyristor Controlled Series Compensator (TCSC). Kapasitas daya saluran transmisi ditingkatkan dengan menambahkan TCSC secara seri dengan saluran transmisi. Untuk meningkatkan aliran daya, reaktansi TCSC dapat disesuaikan untuk memodulasi reaktansi saluran transmisi.Kata kunci: sistem tenaga listrik, FACTS, kompensator seri, tiristor, TCSC ABSTRACTIn order to ensure that the expanding requirements of the community are met and that the system's level of dependability is sufficient, it is crucial to manage and maintain a reliable power distribution system. Due to the extensive transmission distance, it is impossible to prevent installation malfunctions in the electric power system. This has a significant impact on the transmission of electric power, resulting in a voltage decrease and a loss of electrical energy. Using a Flexible Alternating Current Transmission System (FACTS) is one way to reduce voltage instability and improve the dependability of the electrical power grid. A FACTS device is the Thyristor Controlled Series Compensator (TCSC). The power capacity of the transmission line is increased by adding the TCSC in series with the transmission line. In order to increase power flow, the TCSC's reactance can be adjusted to modulate the transmission line's reactance.Keywords: electrical power system, FACTS, series compensators, thyristors, TCSC

Abstract

Reliable and sustainable electrical distribution systems require effective protection measures against internal and external disturbances, especially short-circuit disturbances, to avoid damage to the equipment. Overcurrent relays (OCR) and ground fault relays (GFR) play an important role in the safety of the distribution network. To improve performance, evaluation of relay coordination is essential. During the short circuit, the nearest relay to the fault point is activated first and the backup relay is activated if the fault current exceeds the adjustment of the main relay. Coordination ensures that timely signaling is sent to interrupt the circuit. Inspection of the OCR relay revealed that it did not comply with the IEC 60255 standard and consequently adjusted the classification time to 0.402 seconds. Similarly, the results of the GFR relay inspection did not meet the standards and required an adjustment of the evaluation time to 0.492 seconds. Resolving these deviations is crucial to maintaining the reliability and compliance of the distribution network with industry standards, ensuring that the protection relays respond quickly and effectively to disturbances, thereby preventing possible damage to equipment

Abstract

This study evaluates the performance of 20 kV circuit breakers by analyzing insulation resistance, contact resistance, contact synchronization, leakage current, and power loss. The insulation resistance analysis indicated that phases R and S did not show significant improvement after maintenance, with significance values of 0.065 and 0.166, respectively, while phase T exhibited a significant improvement with a significance value of 0.048. Contact resistance measurements revealed no statistically significant reductions after maintenance, with significance values of 0.209, 0.243, and 0.155 for phases R, S, and T, respectively. Additionally, contact synchronization in the open condition did not experience significant variations, whereas in the closed condition, all phases showed significant declines in synchronization after maintenance, with significance values of 0.003, 0.013, and 0.007. Leakage current analysis at a 20 kV phase-to-ground voltage showed that the highest recorded leakage current was 0.297 mA in the Eks Sumberejo feeder, significantly below the 20 mA threshold. Power loss calculations identified the highest power dissipation in the Depati Hamzah feeder at 69.87 W, with the lowest in the Eks Transmart feeder at 0.376 W. Energy loss assessment further showed the Depati Hamzah feeder experiencing the highest loss at 48.317 kWh, while the Eks Transmart feeder had the lowest at 0.278 kWh. These findings underscore the importance of routine monitoring and targeted maintenance to enhance circuit breaker reliability, optimize operational efficiency, and minimize energy losses in high-voltage electrical networks.

Abstract

During the production of batik cual, thick-colored wastewater is produced. Unfortunately, the wastewater could damage the environment if it is disposed of without specific processing. The Fenton method is an advanced oxidation process (AOPs) that can degrade organic dyes found in liquid waste. In this research, the researchers studied the Fenton mechanism's application to the batik cual wastewater treatment. The Fenton's reagent used was H2O2 with FeSO4.7H2O. Some of the experimental wastewater treatment parameters were the values of biological oxygen demand (BOD), chemical oxygen demand (COD), the degradation efficiency of difficult to decompose organic materials, and the color degradation efficiency in batik cual wastewater. The results show that the Fenton mechanism’s efficiency of removing color from batik cual wastewater is up to 97.8%, COD and BOD removal efficiencies are 76.3% and 75.2%, and the degradation efficiency of difficult to decompose organic matter is 76.8%. Also, the researchers found that the higher amounts of FeSO4.7H2O increase the removal parameters effectiveness. Therefore, the Fenton mechanism can effectively improve the quality of wastewater in batik cual production.
