Abstract

Untuk memenuhi kebutuhan sehari-hari, masyarakat memerlukan banyak listrik dan energi. Untuk memastikan agar energi listrik tersalurkan dengan baik, efisiensi peralatan harus terjaga. Energi listrik yang masuk ke transformator tidak sama dengan energi listrik yang keluar karena adanya rugi-rugi, yaitu arus yang hilang saat melewati transformator tersebut. Efisiensi transformator daya dapat dihitung dengan rumus efisiensi transformator. Pada transformator 60 MVA 150/20kV di GIS Simpang, beban puncak terbesar tercatat 25,70 MW pada tanggal 8 Maret 2024 pukul 19:00, sedangkan beban puncak terendah tercatat 23,05 MW pada tanggal 28 Februari 2024 pukul 10:00. Rugi-rugi total transformator terbesar adalah 2,62 MW yang terjadi pada tanggal 8 Maret 2024 pukul 19:00, sementara rugi-rugi total terendah adalah 2,11 MW pada tanggal 28 Februari 2024 pukul 10:00. Efisiensi pada beban puncak tertinggi adalah 91,5% yang terjadi pada tanggal 28 Februari 2024 pukul 10:00, dan efisiensi terendah pada beban puncak adalah 90,7% yang terjadi pada tanggal 8 Maret 2024 pukul 19:00. Penyebab efisiensi transformator tidak mencapai 100% adalah adanya rugi-rugi pada transformator. Kata kunci: Beban Puncak, Effisiensi, Rugi Rugi Transformator.

Abstract

The occurrence of transient disturbances in the power network can be influenced by several factors, including when a short circuit occurs, motor starting, natural factors and sudden addition of load, which causes frequency instability on the bus. As in this study, an additional load of 10%, 20% and 30% for each feeder can cause transient disturbances which cause frequency stability on the 150kV bus. Frequency experiences instability when there is a transient disturbance caused by an additional load. By simulating using the Etap software, each feeder is given an additional load of 10%, showing a normal state. The 50Hz frequency experiences instability down to 47Hz and stabilizes again at 230 seconds. Hz and rose again at 245 seconds, and when given an additional load of 30% the frequency which was originally 50% experienced instability down to 47.5Hz and stabilized again at 230 seconds.

Abstract

UPT Balai Yasa Surabaya Gubeng has electrical equipment with non-liner load characteristics, which may affect power rating in accordance with PLN and IEEE 519 – 2014 standards. Non-linear loads result in non-compliant power quality parameter values ​​such as voltage, power factor, frequency, and harmonics. The efficiency of the transformer is also determined. due to the generated power from the transformer to the load. This study was conducted by collecting and processing data from LVMDP. It was found that several parameters did not comply with PLN standards. The power factor of LVMDP 1 MVA and LVMDP 200 KVA are 0.8 and 0.7 respectively. Meanwhile, all voltage and frequency ​​of 1 MVA and 200 KVA LVMDP are still according to PLN standards. Whereas, the harmonics of LVMDP 1 MVA THDi R phase (26.18%), S phase (18.83%), THDv T phase (8.86%), and LVMDP 200 KVA THDv T phase (5.58%) are not in accordance with IEEE 519 – 2014 standards. Thus, single tuned filter were simulated which reduce the harmonics of the systems and increase the efficiency of the transformator.

Abstract

Because it provides electrical energy to customers that require protection from lightning interference, the substation is a crucial location. An electrical equipment's defense against lightning strikes is provided by a lighting arrestor. The arrester should be placed as near to the transformer as feasible for optimal protection. In order to restrict the installation of arresters to safeguard equipment, the maximum distance for arrester installation must be established. This study only looks at one 60 MVA transformer in the Surabaya Barat Main Substation, and its goal is to determine the minimum amount of error in transformer protection. Based on the maximum possible surge arrester surge arrester jarak with a power transformer at the Surabaya Barat Main Substation, the maximum possible surge arrester distance is 8,135 meters. Based on surge arrester capability, the transformer may be protected from over voltage since the maximum voltage that can occur is just 150.83 kV, with the maximum voltage remaining below the transverse impulse drop of around 650 kV.

Abstract

A high success rate is required to ensure the continuity of the supply of electricity, so that the distribution of electricity can maintain its availability continuously and have a reliable reliability value. Therefore, this study is intended to help evaluate the reliability of electric power distribution in plate feeders at PT. PLN ULP Kenjeran. The effect of failure on the system caused by equipment failure, as well as its impact on the load point will be evaluated using the section technique method. The results of the calculation show that the value of SAIFI is 2,699 times/year, SAIDI is 5.128 hours/year, and CAIDI is 1.9 hours/disturbance. Based on SPLN No. 68-2: 1986 concerning the reliability index, the value of SAIFI is 3.2 times/year, SAIDI is 21 hours/year, and CAIDI is 6.56 hours/disturbance, where the reliability index value can be categorized in accordance with SPLN standards and is considered reliable. Meanwhile, in the comparison of calculations between the section method and the method without sections, the reliability results were worse. Where the SAIFI value was 3.21112 times/disturbance (up 15.93%), the SAIDI value was 12.4056 hours/year (up 58.65%), and the CAIDI value was 3.9 hours/interruption (up 51.12%).

Abstract

Transmission lines often experience difficulties in determining the location of interference, due to the length of the transmission line. This interference can be secured by using relays, one of which is a distance relay, this tool secures the zone 1, zone 2 and zone 3 areas on the transmission line. Apart from relays, there is also a tool to determine the fault distance, namely a fault locator. These two tools are examples of protection on transmission lines. The method used in this research uses the impedance method to determine the distance the fault occurs and the settings on the distance relay. This technique is often used in electric power systems and is very effective for transmission lines, such as those in Karang Pilang, because of its ability to detect disturbances in transmission lines and equipment. Based on the analysis results, calculating the fault distance using the impedance method shows that the calculated value is very close to the distance measured by the fault finder. Specifically when a short circuit occurs, the impedance method calculates a distance of 14.35 km, while the fault locator measures it at 14.59 km with a margin of error of 1.5%.

Abstract

The large number of inductive loads used, namely 3-phase induction motors and welding machines, has caused a low power factor in the electrical system at PT. Sunrise Steel. In this industry there are 2 production sites for coated steel named Continous Galvalume Line 1 and Continous Galvalume Line 2. There are 6 transformers that supply power to the two places, but there are 2 transformers that have a very low power factor, where Transformer 1 (Continous Galvalume Line 2) a capacitor bank has been installed but the power factor is still low, which is 0.67 and Transformer 3 (Continous Galvalume Line 1) is 0.66. The addition of Capacitor Bank is of course very much needed to increase the value of the power factor in the two electrical systems. This research targets an increase in power factor to 0.98, where Transformer 1 (Continuous Galvalume Line 2) requires the addition of a 17.831 uF capacitor and Transformer 3 (Continous Galvalume Line 1) requires a 2948,81 uF capacitor using an automatic compensation technique. The compensation method used in both is the global compensation method, a capacitor will be installed on each main LVMDP. ETAP Power Station software is used to simulate the results of installing capacitor banks.
