Abstract

Contingency analysis on a 150 kV network aims to see the network's reliability against interference. Contingency is a scheme for releasing one element of the generating unit or transmission line (N-1), which will affect the performance and reliability of the electric power system. Power flow analysis in an electric power system is an analysis that reveals the performance of an electric power system and the flow for certain conditions when the system is working. The analysis was carried out using the ETAP 16.00 software. The method used was the newton raphson to calculate the load flow in the N-1 contingency condition. From the results of the study, it can be seen that the power flow occurs in each channel of the 150 kV system in the South Sulawesi system. When conducting a contingency analysis of N-1 by removing the load on the middle lane of South Sulawesi, namely Maros and Sidrap, a voltage change occurs, increasing buses experiencing critical and marginal voltage conditions. This happens because of the sudden release of essential loads, so over or under voltage appears on the bus.

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.

Abstract

Changes in the load on the electric power system suddenly cause dynamic disturbances. The disturbance causes the stability of the generator to be disturbed, because the generator does not respond to the disturbance quickly. This causes oscillations in the generator in the form of oscillations of frequency and rotor angle. One of the additional control equipment that can increase the stability of a generator is the Power System Stabilizer (PSS). With the PSS installation, the optimal frequency response and rotor angle of the SMIB system are obtained, indicated by the minimum system overshot response. The controller is able to provide stability so that overshoot oscillations can be suppressed, as well as faster settling time performance for the system to reach steady state conditions. To test the stability of the SMIB system, a case study of adding and subtracting loads is used, with the proposed control method using PSS.

Abstract

An overhaul is a process of dismantling a problematic engine so that it can be examined more thoroughly. During the overhaul, the problematic engine components are replaced. The overhaul of the sphere gap setting of the semi-automatic high impulse voltage generation is also intended to maximize the K3 system and the level of accuracy when conducting research on impulse voltage generation. The current condition after the occurrence of damage to the automatic sphere gap adjustment machine. The sphere gap setting is done manually, causing the desired ball gap distance to be not very accurate, and the risk of work accidents is higher in the high voltage laboratory. In the first stage of work, an inspection and measurement were carried out to replace the capacitor and limit switch components because they could no longer be used. As well as improvements to the electromagnetic brake components. From the test results, it was found that the distance measurement was as expected and it can be proven that after an overhaul, the semi-automatic spacer can function normally again so it can make it easier to conduct high voltage impulse research. In addition, from a security point of view, it is better because the spacing between the balls is done outside the high-voltage impulse generation cage
