Abstract

GIS (Gas Insulated Switchgear) is a system of connecting and disconnecting the power grid which is packaged in a non-ferrous tube, using gaseous sulfur hexaflouride (SF6) as the insulation medium. The 150 kV of GIS Pecatu is located in Pecatu Village, South Kuta, Badung Regency, Bali Province. This GIS was built to help supply 120 MW of energy because of the load in Badung area, especially Pecatu and Nusa Dua, is increasing. So, it is necessary to know the differential relay current settings when there is a fault of short circuit in GIS Pecatu to produce an effective, selective and reliable safety system. When there is a fault of 11.58 kA the relay will work immediately within 0 SI, this proves that the differential relay with Instantaneous characteristics will immediately command a trip when the fault current has surpass the set value. From the calculation results, the setting of the main safety relay has worked in appropriate with the SPLN standard No. 52-1 1984 for the 150 kV system.

Abstract

Renewable energy is a naturally available energy source in nature, including wind, bioenergy, geothermal heat, solar radiation, flowing and high-drop water, as well as oceanic motion and temperature changes. Planning for the Micro Hydro Power Plant (PLTMH) in Yeh Dikis Banjar Lebah, Tabanan Regency, utilizes an AC generator as one of the ways renewable energy can be utilized. The literature review and observation methods were employed in this study to determine the turbine rotation speed required to drive the generator and to select the appropriate generator. Yeh Dikis River in Banjar Lebah, Tabanan Regency has a capacity of 30.62 kW, with a crossflow turbine operating at a rotation speed of 539 rpm and a torque of 321.81 Nm. The calculation results indicate that the generator capacity to be used is 21.55 kVA. Therefore, the chosen generator is the Generator Head Alternator with a rotation speed of 1500 rpm, providing an output power of 15.516 kW, a generator current of 31.75 A, and an efficiency of 90%. Since the turbine and generator rotation speeds are not compatible, a mechanical transmission system is required, achieved by designing pulley and belt ratios.

Abstract

Solar Power System as one of the uses of renewable energy whose use is very widespread and one of its implementations is on the roof of the DH Electrical Engineering Building of Udayana University. The increase in the use of solar power plants is followed by an increase in the use of switching equipment such as inverters that produce harmonic distortions and affect the power quality of the electrical system. This investigation aims to analyze the condition of THD in inverters and analyze factors related to THD in inverters, one of which is solar irradiation. THDi output inverter inverter PLTS Udayana University exceeds the permitted IEEE 519-2014 standard, which is a maximum of 5%. The relationship that occurs between irradiation and the inverter of Udayana University PLTS when connected to the load is inversely proportional so that when irradiation is high during the day, the THDi output of the inverter will be low and vice versa in the evening.

Abstract

Potential of renewable energy is essential to support Bali Clean Energy, one of the energy that can be exploited is Solar energy. However, by 2023 the potential has been exploited only 1,48 percent. One of the reasons why Solar Plant construction in Bali is slow is because it is difficult to find land large enough to build Solar Plant on a large scale. However, solution to overcome land constraint is to utilize the water body through floating Solar Plant application. In the Project, the Floating Solar Plant Sidan Dam utilized body of the Water Dam and work pictures from the Planing of the Sidan Dam, with such data being used to determine the Floating solar Plant System in Sidan Dam. The design results showed that floating Solar Plant in Sidan Dam has a potential capacity of 1.45 MWp with a total of 2640 units solar panel and uses 12 units of inverters of 1.100 kW capacity. The energy production produced by the floating Solar Plant in a year was 2.564.007 kWh.

Abstract

Every daily activity requires electrical energy. Electrical energy loads vary. Harmonic distortion is one of the results of current and voltage wave disturbances caused by non-linear loads, such as lamps, computers, and air conditioners, among others. This causes a decrease in the quality of electric power. High resonance disturbances can cause increased harmonics which can reach 4 to 10 times under full charge conditions. One way to overcome harmonic disturbances is by using a harmonic filter. In this study, an active shunt filter with PI control is used to reduce harmonic resonance disturbances. The THD value according to the IEEE 519-2014 standard is obtained by using this harmonic filter. In this study using Matlab Simulink simulation software. The THD obtained before the simulation was carried out, namely THDv in the R phase = 1.62%, S = 1.64%, T = 1.71%, THDi in the R phase = 14.73%, S = 12.96%, T = 13.53%. The THD obtained after the simulation is THDI at each phase R = 3.29%, S = 3.01%, T = 4.53%.

Abstract

The issue of waste, particularly plastic waste, remains a challenging problem without a definitive solution. Plastic waste, especially that made from High-Density Polyethylene (HDPE), takes an extensive amount of time to decompose. Currently, plastic recycling machines are priced in the hundreds of millions, making them less accessible. Therefore, there is a need for affordable machines that function effectively alongside existing ones. This research introduces a hot press machine for recycling HDPE plastic. The hot press machine is capable of recycling HDPE plastic waste and offers the advantages of being portable, compact in size, and cost-effective. Following the design phase, the machine is capable of producing plastic boards with a thickness of 1 cm, utilizing 3.7 kg of plastic, and requiring a molding time of 2 hours and 15 minutes at a pressure of 4.36 MPa.Subsequent testing involved analyzing three factors to determine the significant influence of factor A (heating temperature) and factor B (heating time) on energy consumption. The goal was to identify the interaction that yielded the smallest average energy consumption.
