Abstract

The need for electrical energy has increased from time to time in accordance with the increase in population and industrial development. However, the current availability of electrical energy comes from fossil energy and this makes the availability of fossil energy in the world dwindling. Therefore, renewable energy is needed to meet future electrical energy needs. In Indonesia, there is a lot of availability of renewable energy such as wind energy, solar energy, water energy and others. This research will focus on solar energy using a photovoltaic inverter with switching control techniques using sinusoidal pulse width modulation (SPWM). The results of SPWM design for inverter switching control have been simulated using Mathlab Simulink. The results of this simulation have resulted in the inverter output waveform approaching a perfect sinusoid. The content of voltage harmonics in the output waveform of this inverter is already below the standard set with a THDv of 2.69%. Meanwhile, the inverter output current harmonic is THDi 15.09%. From the results of this study, it can be seen that the inverter output using the SPWM control technique has been successfully implemented with harmonics below the specified

Abstract

The Campus III area of Imam Bonjol State Islamic University Padang is located in the Bangek River area, Balai Gadang Kec. Koto Tangah, Padang-West Sumatra, with an area of 39,000 m2. The Campus III area of Imam Bonjol State Islamic University, Padang consists of 8 lecture buildings which are divided into 2 electricity distribution zones. PLN (Persero), 20 kV medium voltage system. Each building has a panel that is supplied with electricity from a low voltage panel (PUTR). The distribution of the load for each building has different distances, some are near and far from the power source. The total power in the Campus III area of Imam Bonjol State Islamic University, Padang is 3,069.1 kVA with a TDL of PT. PLN (Persero) 3.465 kVA voltage 20 kV. The ground cable used is NYFGbY type with sizes 4x150mm2, 4x185mm2 and 4x240mm2. From the results of the calculation of the voltage drop from the existing data, the largest voltage drop was obtained at 155.13 volts or 40.82% and the smallest voltage drop was obtained at 2.58 volts or 0.67%. the largest voltage was obtained at 9.16 volts or 2.41% and the smallest voltage drop was obtained at 2.58 volts or 0.67%. From the results of the calculation of power losses with the data obtained, the results of power losses at 32,905.58 Watts (0.9%). While the calculation of power losses analysis results in 21,642.11 Watts (0.59%). From the simulation results of losses and voltage drop at ETAP 12.6, the highest voltage drop is on MDP 1-SDP L with a percentage of 4.34% and the value of losses is 10.7 kW and the lowest voltage drop is on MDP 1-SDP J with a percentage of 0.60% and the value of losses is 1.0 kW.

Abstract

PLTM Gunung Wugul is a power plant that utilizes the type of river flow "run of river" which operates with Commercial on Date (COD) on December 3rd, 2021, by PLN Central Java & DIY Distribution Controlling Unit (UP2D). PLTM Gunung Wugul uses a French turbine type with a net head of 68.5m and uses a synchronous generator type with a capacity of 2100 kVA with a cos phi generator capability of 0.8. The generator for the Gunung Wugul PLTM is currently operating with a power factor of 0.95, which PT PLN has asked the PLTM Gunung Wugul to run at a power factor of 0.9. PT PLN assesses that the reactive power production of the PT Indonesia Power plant is still lacking, so a reactive power plant support clause is added with a minimum cos phi 0.9. This results in changes to the operating parameters of the generator. This writing method contains the steps taken by the author in compiling this final project. This writing method is structured to provide clear directions and ways for writers so that the preparation of this thesis can run smoothly. Based on the analysis of operational data for the Gunung Wugul PLTM, the recommended cos phi setting is 0.95. In these conditions, the operating parameters of the unit are in the normal operating conditions and range. Based on the technical specifications of the equipment, the PLTM Gunung Wugul can be operate with a cos phi setting of 0.9. However, these conditions must also see the operating parameters, apart from that the network voltage condition on the MRA03 is currently stable at 20 kV, with operation at cos phi 0.9 it will make the network voltage very high at MRA03-337, with a maximum voltage of 21 kV
