Abstract

One of the most important components of a power plant is the generator, the change in a load will affect the voltage of the generator. The excitation system also has the task of monitoring and controlling the output voltage of the generator, therefore the generator must be able to generate electrical power in accordance with the amount of load given. The purpose is to compare the results of EDS measurements with the results of the calculations obtained, which will be analyzed with the aim of minimizing the occurrence of interference with excitation and reactive power in the generator. The analysis shows that the largest excitation current is found at 21:00 setting the excitation current by 868 A, the resulting voltage is 16.0 kV, while from the calculation results of 15.8 kV, from the comparison of measurements with calculations having 0.2 kV or 200 V. At 09:00 with an excitation current of 778 A, with an anchor current of 7.9 kA the reactive power produced is 25 MVAR, while in the calculation of the reactive power obtained at 24.6 MVAR, in the measurement with the calculation has a difference of 0.4 MVAR or 400 kVAR. At 22:00 it gets a reactive power of 15 MVAR so that it produces a power factor of 0.96, while in the cosphi calculation which is obtained at 0.95. It can be concluded that the greater the excitation current, the generator output voltage will be large, if the excitation current is large, the reactive power will also be large, if the reactive power is large, it will cause cosphi to decrease because the reactive power is inversely proportional to cosphi which will later cause power losses.

Abstract

Predictive industrial machine maintenance techniques have been applied in the industrial world, one of which is induction motors. The problem that occurs with induction motors is misalignment, namely damage caused by misalignment between the motor clutch and the blower load clutch. Analysis and data collection is carried out while the motorbike is operating. The resulting vibration and spectrum signals aim to facilitate data analysis according to the type of damage and vibration characteristics. Use of ADASH vibration equipment with digital diagnostics system (DDS) software and repair of misalignment using shaft alignment equipment using the laser method. The resulting data is an initial horizontal offset data value of 0.20 mm and a vertical offset of 0.17 mm. Misalignment correction produces a vertical value with an angular side of 0.00 mm, and an offset of -0.02. Meanwhile, the horizontal section has an angular side value of -0.02 mm, and an offset side of 0.01 which results in the excellent category with an operating speed of 3000 RPM. Vibration data with loads after repairs were carried out, the vibration measurement results showed that horizontal side DE was 0.55 mm/s, vertical DE 0.23 mm/s, axial DE 0.54 mm/s, horizontal NDE 0.43 mm/s, vertical NDE 0.25 mm/s, and Axial NDE 0.57 mm/s. Repairs are carried out based on vibration values in tests with loads in zone A (new machine condition) based on ISO 10816-3 standards.

Abstract

In order not to be disconnected from the electrical energy source, a backup system is needed. One way is to use a charging system when PLN is on and storing it in an accumulator for use during a PLN blackout. However, when charging, the electricity stored in the accumulator is in the form of DC current, so it needs to be converted back to AC current, namely with an AC to DC inverter. The inverter system uses switching which creates harmonics. Disturbances in the electric power system caused by wave and current distortion are called harmonics. Harmonics can cause sinusoidal waves to become less sinusoidal, caused by high frequency waves which are multiples of the fundamental frequency. To reduce harmonics, install an EMI filter at the inverter output. This research measures the effectiveness of installing a filter using Labview 2014 software on a 500 W custom low inverter with inductive, resistive and capacitive loads using Labview software and the NI myDAQ instrument. The results of the research are that the standby/no-load power required for the common mode EMI filter is 0.03 A’s at a voltage of 220VAC. In no-load conditions there was an increase in THDv of 0.03 from before the filter 1.7% to 1.739%, and a decrease in THDi of 0.12 from 1.311% to 1.119%. In conditions with inductive loads, there was a decrease in THDv by 0.104 from before the filter 1.202% to 1.098%, and THDi by 0.099% from before the filter 1.325% to 1.226%. In conditions with resistive loads, there was a decrease in THDv of 0.12 from before the filter of 1.218% to 1.09%, and THDi of 0.003 from before the filter of 1.144% to 1.114%. In conditions with capacitive load, there was an increase in THDv of 0.185 from before the filter of 1.219% to 1.404% and a decrease in THDi of 0.035 from before the filter of 1.44% to 1.109%.

Abstract

The failure of electrical components in the industry can cause production process disruptions, and even accidents. Infrared thermography is an effective method for predictive maintenance, aiming to identify potential component damage before failure occurs. This research aims to analyze the condition of a 575 kVAr capacitor bank installation using infrared thermography. The standard used is the Standard for Infrared Inspection of Electrical Systems and Rotating Equipment. The results of the study indicate that the majority of the 575 kVAr capacitor bank installation conditions fall under priority scale 3, with a maximum temperature of 44.5°C and a delta T of 18.3, which means corrective actions need to be taken with scheduling permission. Corrective actions that can be taken include inspecting cable installations, tightening cable lugs, and tightening terminal connections on contactors and MCCBs. One part that has a priority scale 4 is the MCCB and contactor of the capacitor bank on the lower front section, with a hot point value of 35.1°C and a delta T of 8.9.
