Abstract

The generator is one of the main components in the Teluk Sirih PLTU as a producer of electricity that will be supplied to consumers. The generator itself is not spared from existing disturbances. One of the disturbances that can occur in a generator is an overcurrent disturbance caused by a short circuit. Therefore the generator must be given a protection, namely an overcurrent relay which is useful for giving a signal to the PMT to open the circuit. In this report, we will test the performance of the overcurrent relay installed on the generator by looking for settings based on a 3-phase short circuit fault in one of the bus areas. The data used is in the form of Generator, Transformer and Overcurrent Relay specification data. Then from the data a series will be made and simulated using the ETAP 19.0.1 application. Based on the simulation that has been carried out, it is found that the magnitude of the 3-phase short circuit fault current in the Bus 2 area is 41501 A. Meanwhile for the overcurrent relay setting, the relay current is 3.39 A, the set current in the relay setting is 5982.757 A and the time is 0.34 s with a CT ratio of 1600:1. The result obtained is that the relay works according to the existing settings when a fault occurs and instructs the PMT to open the circuit.

Abstract

Kuko Palm Oil Mill, currently not interconnected with PLN electricity, relies on diesel-fueled generators of 1100 kVA and 650 kVA to meet its electrical needs. To reduce diesel consumption, a Hybrid Power Plant (PLTH) system comprising generators, batteries, and Photovoltaic (PV) panels is proposed. Optimization studies, evaluating technical and economic feasibility, are conducted using HOMER software. Optimal PLTH configuration includes 8,727 kW PV, 500 kW generator, 1,000 kW generator, 25,708 battery units, and 1,481 kW converter. PLTH generates 14,339,116 kWh/year, fulfilling PKS electricity requirements. Economic analysis yields NPC of Rp356,000,000,000, initial investment of Rp77,400,000,000, operation and maintenance costs of Rp21,600,000,000, and LCOE of Rp3,147/kWh. IRR stands at 22%, NPV is positive at Rp124,000,000,000, with a 3.5-year capital return. These results indicate PLTH feasibility both technically and economically
