Abstract

At the Cikalong hydropower plant there are 3 power transformers with a voltage rating of 6.3/77 kV, because of their long life, it is necessary to analyze the condition of the transformer oil. One way to determine the level of fault gas contained in transformer oil is the DGA (Dissolved Gas Analysis) test. DGA will extract the gas to find out indications of disturbance based on the interpretation of the dissolved gases data, namely the Total Dissolved Combustible Gas (TDCG), Key Gas, Roger's Ratio, Doernenberg's Ratio and Duval's Triangle methods. This method is in order to determine the condition of the transformer oil is normal or not, measure the breakdown voltage value and calculate the correlation value between operating hours and the amount of power production. The results of the DGA analysis on transformer units 1, 2, and 3 of the Cikalong hydropower sub-unit show the TDCG value in condition 1, which includes all transformers in good condition. The value of the correlation coefficient between hours of operation and the number of kWh production with TDCG is 0.267 and 0.297, respectively, which indicates the relationship between these variables is a weak relationship (standard value is close to 1).

Abstract

The CT saturation analysis approach model was carried out using ATPDraw and Mathcad software simulations. Input simulation data obtained from CT testing at West Priok Substation, namely ratio, excitation curve V-rms-Irms, Rct. Based on the simulation results, the CT model was successfully implemented for CT conditions at the West Priok Substation which experienced saturation, as seen from the results of the distorted waveforms and the THDi value of 40.612%. These results are then compared with the IEC 61869-2 standard with the parameters obtained from the CT-Analyzer test on E-t, Ek, Ie, Kx, and Rct, that E-t is -1%, Ek is 635.25 V, Ie is 13.5 mA, Kx of 0.084 and Rct of 7432.57 ohm. This result is a deviation from the specified standard, meaning that the CT is damaged and saturated. After replacing the CT, it was tested again and the value of E-t was -0.010%, Ek was 936.09 V, Ie was 9.68 mA, Kx was 14.39 A, Rct was 4.226 ohm, and the waveform simulation results were not distorted, then the THDi value obtained by 0.08%. This indicates that the CT is in good condition and does not experience saturation when the short circuit current is 20 kA.

Abstract

Problems that often occur with electricity distribution network quality, continuity and availability services consumers. Study aims evaluate reliability of the 20 kV medium-voltage electricity distribution system at the Suci ULP Garut Kota feeder, where 2021 Suci feeder experienced 14 disturbances duration 791 minutes (13.1 hours), including a medium-voltage overhead line that broke 2 Phase. Determining the reliability index value electricity distribution system of the Kudus ULP Garut City feeder, mathematical calculations were carried out using RIA-section technique predetermined formula and simulated using ETAP software with study case reliability assessment. Based on the results of the study, improvement was made that the reliability value feeder was stable. Repairs were carried out 2 times, first repair, 2 fuse cutouts were installed and 4 transformers were moved, while the second repair was to divide the Suci feeder into 2 parts, namely the western Suci feeder and the eastern Suci feeder. So making these improvements the reliability index Suci feeder becomes stable and meets what has been SPLN 68-2: 1986, which is below SAIFI 3.3 times/customer/year and SAIDI 21.9 hours/customer/year.
