Abstract

Maximum Power Point Tracking (MPPT) modeling has been developed which is part of a photovoltaic (PV) system. This study applies an algorithm for tracking maximum power points in the photovoltaic unit as a whole. The algorithm applied to the MPPT is simulated in PROTEUS modeling to verify the proposed method, the PID control method is simulated in Matlab and Simulink. Simulation shows that changes in input current and voltage will produce different PID controls, with a PWM duty cycle of 10% to 99%.

Abstract

The reliability of the electric power system is very important in the continuity of the supply of electrical energy to the load. One of the important parts in the electric power system is the transformer. Maintaining the reliability of the transformer is an effort to make electrical energy channeled properly. For this reason, efforts are needed to evaluate whether the transformer is in good condition or not by using the Weibull distribution. By looking at the average failure rate, the MTTF value is used as a benchmark for reliability. It is based on the number of disturbances that cause the transformer to fail to operate. The results of the reliability analysis with the Weibull distribution on distribution transformers in the Rungkut ULP area during the time span from 2019, 2020, 2021 obtained an average failure rate of 18.321894% per year, with an MTTF value of 0.054579 per year, so the value reliability obtained 0.981. So according to Croanbach alpha, this value belongs to a very reliable level.

Abstract

Abstrak— Kebutuhan energi terus mengalami peningkatan setiap tahunnya yang menyebabkan peningkatan konsumsi energi secara global. Industri merupakan Salah satu sektor yang terus membutuhkan energi skala besar. CV. Wana Indo Raya merupakan salah satu industri yang membutuhkan energi secara kerkelanjutan untuk aktivitas kerjanya. Di sisi lain, CV. Wana Indo Raya berperan aktif dalam meningkatkan efisiensi energi dalam operasional industri dengan melakukan audit energi secara berkala. Salah satu parameter yang digunakan secara luas untuk menentukan efisiensi suatu bangunan adalah perhitungan Intensitas Konsumsi Energi (IKE). IKE adalah indikator yang ditentukan dengan menghitung penggunaan energi per satuan luas per bulan. Daerah ukur CV. Wana Indo Raya Lumajang dibagi menjadi dua, yaitu MDP 1 dan MDP 2. Hasilnya, IKE pada MDP 1 sebesar 6,1 kWh/m2/bulan yang masuk dalam kriteria ”cukup efisien”, dan MDP 2 sebesar 1,8 kWh/m2/bulan yang masuk dalam kategori ”sangat efisien”. Bangunan pada CV. Wana Indo Raya berventilasi alami sehingga tidak membutuhkan AC sebagai pendingin. Sehingga, efisiensi energi dilakukan dengan mengganti lampu CFL menjadi LED. MDP 1 dan MDP 2 mengalami penghematan penggunaan listrik sebesar 34,3% pada sektor penerangan ruangan. Hal tersebut menyebabkan perubahan nilai IKE menjadi lebih efisien namun tidak signifikan yaitu 6,07 kWh/m2/bulan pada MDP 1 dan 1,79 kWh/m2/bulan pada MDP 2.

Abstract

The quality of lighting in Public Street Lighting greatly affects the comfort of road users. The unevenness of public street lighting (PJU) which can trigger accidents is influenced by several factors including the width of the road, the height of the poles, the distance between the PJU lamp power poles and the light angle. The width of the road and the height of the poles affect the maximum distance that can be reached by the PJU. The distance between the poles determines the width of the dark position that occurs and the power of the lights. The Uneven Lighting Technical Study on PJU installation in this study was carried out by simulating using PJU S09 RUSH Series lights from the BANDDEL brand with a power of 90 Watt, and the pole height was made variable from 7.5 meters, 8 meters and 9 meters, the distance between the poles was 40 meters and the width walk 6 meters. The results showed that at a pole height of 9 meters, the lighting unevenness occurred at a distance of 18 m from each pole with a lighting intensity value of 7.38 Lux. For a pole height of 8 meters, the lighting unevenness was obtained at a distance of 15 to 18 meters The value of lighting intensity is 6.8 to 7.7 lux from each pole. Whereas at a pole height of 7.5 meters, the light inequality value is obtained at a distance of 15 to 18 meters with a lighting intensity value between 4.68 to 8.09 Lux.

Abstract

Introduction of Solar Panels as a Renewable Energy System for high school students in Surabaya City. In particular, the city of Surabaya can be an effort to support the realization of the Sustainable Development Goals (SDGs) program. The team has held online discussions with partners, namely SMAN 20 Surabaya to carry out the introduction of solar panels as a renewable energy system to students at SMAN 20 Surabaya. The purpose of community service is to socialize the use of solar power plants through learning activities (education) and solar power plants training for school students and teachers. The method used in this activity is divided into three stages. In the first stage, field observations were carried out to find problems related to the availability of electrical energy in schools. In the second stage, the implementation of community service includes the delivery of solar panel material with lectures, demonstrations, and the design of solar power plants systems at schools. In the third stage, it is an evaluation or feedback stage by giving questionnaires to participants. The results of this community service activity provide information on understanding solar panels and batteries in the good category. Practical activities need to be taught to student, so solar power plants teaching aids are needed at the school. The team made an educational activity for students, namely a demo of converting solar energy into electrical energy. The implementation of this community service has been carried out well.

Abstract

The transmission system is the stage of electricity distribution from the generator to the substation to the distribution system. During the process of distributing electric power, there is a voltage regulation that occurs whether it is still within safe limits or not because if it exceeds safe limits it can cause damage to electrical equipment. Power losses can occur due to several factors, namely insulator leaks, distance, and others. One of the issues identified is the use of ACSR (Aluminum Conductor Steel Reinforced) conductors, which, although commonly used due to their mechanical strength and relatively low cost, also contribute to significant power losses due to their resistance and susceptibility to environmental effects such as temperature rise. The transmission network in this study uses ACSR type conductor wire with a Dove type and a cross-sectional area of 327,77 mm² over a distance of 251 km, with a resistance value of 0.1024 Ω/km. The manual calculation method was employed by recording current and voltage values that change every day for one month. The conclusion obtained from manual calculations of power losses and voltage regulation is that the percentage of voltage regulation on transmission lines for one month remains within the safe limit, where the maximum allowed is 10 percent. However, despite the voltage being regulated within limits, significant power losses were recorded, with the highest loss being 16,79 MW and the lowest 6,01 MW. The total power losses on the transmission network for one month reached 272,92 MW, with an average of 9,09 MW per day. These findings highlight the drawback of using ACSR conductors in long-distance transmission lines, emphasizing the need for consideration of alternative conductor types or loss-reduction strategies to improve overall transmission efficiency.
