Abstract

PLTMH is one of the renewable energy power plants that is environmentally friendly. Indonesia has considerable hydropower potential that can be developed into Micro / Mini Hydro Power Plants of 19,385 MW spread throughout Indonesia [2]. PicoHidro Power Plant is part of PLTMH with an output power of < 1 kW [1]. The advantages of this plant are generating electricity without being too influenced by seasons and day and night changes, power generation fluctuations are relatively small, the possibility of electricity generation is high, the impact on the environment is very small and the fast response is suitable for peak load conditions and when there is a disturbance in the network. PLPicohidro uses a DC generator that utilizes a power source for battery charging. The battery is used as an inverter voltage source to turn on the AC load. For that, a Charger Controller is needed which is useful for charging the battery. The DC voltage source coming from the generator is stored using a battery and then goes to the inverter to be converted into AC voltage. In this study, automatic charging of two batteries was used or can be called automatic charging. The way this circuit works is when the battery is full, the charger will automatically stop. The voltage indication during the charger process is 11 Volts and stops when the voltage reaches 14 volts. The use of two batteries in the charger process can work alternately, if battery 1 is full then battery 2 will charge automatically, and vice versa.

Abstract

power flow in an electric power system is an event that flows in the form of active power (P) and reactive power (Q) from a generating system (sending side) through a transmission line or network until it reaches the load side (receiving side). . This power flow analysis has complicated stages if done manually, which requires an ETAP program. ETAP (Electric Transient Analysis Program) is software used to analyze an electric power system. This research was planned in the electrical engineering laboratory, Faculty of Engineering, Batanghari University, while the data was obtained from PT PLN (Persero) UIWS2JB Jambi. The ETAP method can simplify the calculation of the power flow in the palm feeder at PT PLN (Persero) Jambi.

Abstract

During the distribution of electric power, there are power losses which occur in both the line and the transformer. Power loss can be identified if the voltage at the transmitting base (generator) and the receiving base is different from research data. Power loss is energy loss that cannot be avoided. It is important to anticipate and examine energy loss in order to ensure it stays within acceptable boundaries. A lack of electricity supply in an area will result in low voltage, even power outages. The voltage and current at peak load every day are taken at 14.00 WIB and 22.00 WIB. The distance from the Aur Duri substation to the Payo route is 19 km, as this transmission line enters the short transmission line. The power losses that occur when sending power from G.I Aurduri to the Payo Selincah department are quite large. However, these losses still meet the requirements for the feasibility of transmission lines according to PUIL PT. PLN (Persero) 2010, namely not more than 10%. The cause of power loss is due to several factors, namely insulator leaks, long distances, environmental temperature, lack of current flowing and the conductor table material used.

Abstract

In electric power systems, power flow studies are conducted to gather data on power flow. Including active and reactive power, voltage on each bus, voltage magnitude and phase angle, active and reactive power flowing through each channel, and the state of every piece of equipment to ascertain whether it satisfies the necessary standards for distributing the necessary electrical power. In this research, ETAP software is used to simplify and speed up the power flow calculation process. According to the analysis's findings, the higher the transformer load percentage, the smaller the voltage. The smallest voltage at point JE383 – JE507 which is located at the end of the line is 19,719 kV with an assumed load of 95%. The greater the transformer load percentage, the greater the current. The largest current is located at the base, namely at the PLTMG – JEX109 point of 49.2 A with an assumed load of 95%.

Abstract

PT PLN (Persero) ULP Telanaipura showed significant improvement in overcoming customer complaints. Customers can now report their complaints practically through the PLN Mobile application or direct visits to the nearest ULP office. This efficiency is driven by the Integrated Complaints and Complaints Application (APKT), a web-based internal system at PLN. APKT is designed to process all types of complaints and grievances received from call centers 123, ensuring prompt response and resolution as per the set time standards. Prior to the implementation of APKT, complaint management was still conventional, not integrated, and without real-time monitoring. The presence of APKT has eased the workload of PLN employees throughout Jambi City rayon, allowing for faster and easier resolution of customer complaints. This study focuses on the effectiveness of the APKT system in customer complaint management at PT PLN (Persero) ULP Telanaipura. If customers have complaints, they can contact the PLN 123 call center. The customer service operator will provide guidance and gather the necessary technical information. The most dominant interference that customers often complain about is interference with the code 99110 (approximately 3.93%), which is often associated with "clear tamper" and "voltage drop" issues. In contrast, the 99115 code disruption, i.e. complaints of misinformation with unidentified causes, is very rare, accounting for only about 0.16%.
