Abstract

Penelitian ini mengevaluasi keandalan submarine power cable 20 kV Bangka-Lepar. Submarine power cable ini juga menggambarkan jaringan distribusi tegangan menengah di Bangka-Lepar dan menentukan korelasi berbagai parameter yang mempengaruhi operasi jaringan kemudian memberikan informasi tentang prosedur peletakan kabel. Selanjutnya penelitian dilakukan dengan analisis reliabilitas berdasarkan model statistik. Model ini digunakan untuk mengevaluasi karakteristik operasional kabel seperti tingkat kegagalan dari penyebab alami atau manusia serta juga digunakan untuk memilih antara dua rute kabel dan menentukan satu keandalan maksimum.

Abstract

This paper discusses the design and simulation of the Cascade Greinacher circuit to increase the dc output voltage and current. The voltage increasing circuit using the Cockroft-Walton method has a large output voltage ripple and voltage drop. Meanwhile, half wave and full wave rectifier circuits are only capable of producing a DC output voltage and do not reach the maximum voltage value. In addition, the load resistance at each input power saturation is different and high frequencies require the addition of a capacitor circuit. Therefore, the Greinacher Doubler Circuit (GDC) rectifier is proposed with a modified diode and capacitor series arranged in nine levels in parallel. The circuit modification is used as a DC output voltage rectifier to reduce output voltage ripple. Then the circuit modification was tested by simulating the PSIM software and varying input voltages. Simulation testing uses a 220 volts voltage source, 50 Hz frequency, and component specifications for a single-phase step-down transformer 220 to 12 volts, 8 diodes (DXN, DN/DXN1, DN1/DXN2, DN2/DXN3, DN3), 8 capacitors with 4700Uf value (CXN, CN/CXN1, CN1/CXN2, CN2/CXN3, CN2), and 100 Ω resistor. simulation results which produce a voltage greater than 3 times the input voltage, namely 35.7 V and a current of 0.98 A. Even though at times 0.001 seconds and 0.0035 seconds and 0.0054 seconds the output voltage and current are constant at 4.9 volts respectively, the current is 0.03 A, current 0.08 A and current 0.013 A. The output voltage Vout, Vs and current continue to increase when it reaches 1 second.

Abstract

This study aims to evaluate the impact of RLC loading on the power stability and power quality in Wind Power Plant (PLTB) systems. The RLC is applied to stabilize the power generated by the PLTB system, which tends to fluctuate due to wind speed variability. The testing was conducted by measuring the output power of the PLTB system loaded with various RLC configurations. The results show that RLC loading can enhance the apparent power stability and efficiency of the PLTB system. The resistive load (R) yielded the best performance, improving the power factor to 0.95 and maintaining relatively stable output voltage. Meanwhile, the LC loads exhibited lower efficiency with a reduced power factor, but still played a role in balancing reactive power. The reduction in reactive power for inductive and capacitive loads indicates that RLC loading can help reduce power waste and improve power quality. This research makes a significant contribution to the development of more efficient and stable PLTB systems and more reliable renewable energy-based power plants, particularly in managing power stability in the face of fluctuations caused by wind variability.
