Abstract

Voltage harmonics in the power system can interfere with the work of equipment and reduce the quality of electrical power. This is overcome by using a Series Active Power Filter which is a three-phase Voltage Source Inverter (VSI). The artificial neural network compensation method is used as the control circuit of the Series Active Power Filter to generate a reference voltage from the harmonic distorted and unbalanced source voltage. The artificial neural network determines the amplitude of the sine and cosine components of the reference voltage. Computer simulation results show that the three-phase Series Active Power Filter with artificial neural network compensation method is effectively able to remove harmonics and produce a sinusoidal and balanced three-phase voltage that will be received by the load..

Abstract

Ahuru feeder is the feeder with the longest network of all Ambon city distribution networks. So it is predicted that losses will occur in the network because the longer the distribution channel, the greater the voltage drop. Voltage drops in the network cause energy losses (losses) which need to be evaluated and anticipated whether they occur within normal and reasonable limits. So in this research an evaluation of the voltage profile of the Ahuru feeder was carried out using the power flow analysis method using ETAP 12.6.0 software. Based on the simulation results, under installed load conditions, there is a voltage drop below the PLN standard on the BusL-ERIE3 line of 18.99kV or 95% up to the end of the BusL-WAYOMAR series network of 18.907kV or 94.5% of the nominal voltage of 20 kV. Meanwhile, the base, middle and end line voltage profiles are based on simulation results, the installed load conditions produce a base voltage level of 19.77kV with a voltage drop of 1.2%, the middle of the line 19.09kV with a voltage drop of 3.3% and the end of the line 18.907kV with a voltage fell by 4.3%. Repairing the line voltage profile using capacitor banks on lines and buses that experience voltage drops, namely on BusL-ERIE3 of 2x400 kVAR, is able to improve the voltage profile at the base of the line by 19.804kV or 99%, the middle of the line 19.24kV or 96.2% and the end 19,074kV line or 95.4%.

Abstract

PLN's electricity supply is not always continuous in the process of distributing power, because under certain conditions there will be blackouts caused by interruptions or maintenance in the distribution system. An alternative to overcome PLN disturbances is to use renewable sources such as solar power plants and generators with an ATS automatic control system controlled using PLC. This study conducted a literature study to collect relevant theories and references about this research. PLC diagram leaders are designed for the process of transferring PLN, PLTS and Generator to load electrical power. Solar power plants operate during disruptions to PLN resources during operational hours (10 a.m. – 3 p.m.) and generators operate when solar power resources cannot supply to the load and at night outside solar power plant operating hours. The ATS system is able to switch the process of switching PLN and PLTS power sources very quickly without any time lag so that the load is directly supplied by PLN and PLTS power sources. The process of switching the generator source takes approximately 2 seconds for the starting process. The process of transferring battery power resources to critical loads without any time lag during the generator starting process and when generator starting failure occurs.

Abstract

Short-circuit faults are a type of disturbance that impedes the transmission of electrical energy. To protect equipment from the impact of such faults, short-circuit analysis is conducted. In this study, the magnitudes of phase-to-phase and phase-to-ground short-circuit currents are calculated, along with the determination of overcurrent relay and circuit breaker ratings on the distribution network of PT PLN Saparua Rayon, Maluku. The analysis is carried out using ETAP software on generator busbars and feeders at various fault locations. PT PLN (Persero) Saparua Rayon operates four feeders: Saparua, Pohar, Tenggara (Southeast), and Hatawano. Simulation results show that the Saparua feeder has the highest fault current at bus 6 under an L-L-G fault condition, while the Tenggara, Hatawano, and Pohar feeders exhibit their highest fault currents at the generator bus under an L-G fault. It is evident that the L-L-G (double line-to-ground) fault consistently generates the highest short-circuit current when compared to other types of faults such as L-L (line-to-line) and three-phase faults. This type of fault involves a direct connection between two phases and the ground, resulting in a larger fault current due to lower overall impedance at the fault point. Furthermore, it was observed that the magnitude of the short-circuit current decreases progressively with increasing distance from the power source. This behavior is primarily due to the increase in line impedance along the distribution path, which naturally limits the fault current as it travels farther from the generation point. In summary, the farther the location of the fault from the generator, the lower the resulting short-circuit current, which highlights the critical role of impedance in fault current behavior across the distribution network.
