Abstract

Kilo Watt Hour Meter or kWh meter is a tool for calculating the amount of electrical energy used by electricity consumers, both residential and industrial customers. The electrical energy used is then converted into the electricity price that must be paid each month. Currently, most kWh meters in circulation are smart kWh, which use electricity tokens as transaction calculations. Customers must fill in 20 token numbers via the kWh meter keypad to fill in electricity tokens. Filling in this 20-digit token is not easy, this is because usually, this type of kWh is placed in a higher place to avoid the reach of children. This placement sometimes causes problems with replenishing the token, and users must start over from the beginning. This research aims to create a tool to fill in electricity token numbers that can be controlled using an Android application, making it easier for users to fill in electricity tokens remotely via smartphone. Apart from that, this system has feedback in the form of notifications that display numbers that failed to be filled in on the kWh meter. Test results show that this system can function well from 10 meters without obstructions and 9 meters without obstructions.

Abstract

Torque ripple analysis and calculation methods in an axial-type Magnetic Gear (MG) design with four rectangular NdFeB magnetic layers have been reviewed and discussed. Smooth and steadily transmitted torque is an essential characteristic of a magnetic gear. Reducing possible mechanical vibration, position inaccuracy, and acoustic noise is necessary. Therefore, this study aims to design a new engineering method appropriate for calculating the torque ripple of the MG transmission by testing its mechanical and electrical properties. Two simultaneous torque tests compare the MG brakes from zero to full load. In addition, the transmission torque of the axial MG is measured and calculated using technical methods. The results showed that differences in dynamic torque occurred in the MG at various air gap distances.

Abstract

Based on the 2021-2030 RUPTL, the addition of PLTU Timor 1 (2 × 50 MW) to the Timor system is carried out because electricity demand continues to increase. Therefore, a transient stability study is needed, to determine the reliability of the system when a disturbance occurs. By utilizing the Time Domain Simulation (TDS) method, the research was conducted by simulating generator outage and 3 phase short circuit to study the frequency stability of the Timor system. From the simulation results, generator outage has a major influence on system frequency stability, especially simulated at PLTU Timor 1 unit 1. The disturbance caused a decrease in the lowest frequency reaching 49.61 Hz so that it was not within the safe operating limits according to the operating guidelines for the Timor electricity system. For this reason, Manual Load Shedding (MLS) and the addition of generators at PLTD Cogindo and PLTMG Kupang Peaker are required. The action is carried out by paying attention to the rate of change of the next frequency. As for the 3 phase short circuit disturbance on one of the Bolok - Maulafa lines, the frequency increased to 50.06 Hz after the disturbance which is still within safe operating limits.
