EFEKTIFITAS KINERJA SOLAR CELL PADA PLTS DENGAN SUMBER 50WP

The need for electricity for both industry, offices, and the general public and individuals is greatly increasing. However, this increase in electricity demand was not accompanied by an increase in electricity supply. Based on these problems, solar energy is chosen as an alternative energy to produce electrical energy. The tools used here are solar cells, because they can directly convert solar radiation into electrical energy (photovoltaic process). So that solar energy can be used at night, during the day the electrical energy produced is stored first to a battery which is controlled by the regulator. The regulator output is directly connected to the inverter from DC to AC currents. The results of solar module testing (photovoltaic) show that the results of research with a 50WP solar cell can use a maximum load of 325 Watts. This is because the solar cell when following the direction of the sun's movement will always position the solar cell to remain facing the sun so that it will still be able to capture the sun's rays to the maximum

Analisis Pengaruh Rugi-Rugi Daya Pada Jaringan Transmisi 150 kV Menggunakan Software Etap 12.6

Sistem kelistrikan pembangkit serta pusat- pusat beban pada biasanya terpisah dalam ratusan apalagi ribuan km, sehingga tenaga listrik yang dibangkitkan wajib disalurkan lewat penghantar jaringan transmisi. Sumber tenaga listrik meliputi 3 tahapan semacam sistem pembangkit, jaringan transmisi serta distribusi, sehingga memunculkan kendala dalam proses penyaluran tenaga listrik. Salah satu kendala diakibatkan oleh aspek rugi- rugi energi akibat jarak antar pusat pembangkit dengan pusat beban yang jauh. Pengaruh dari rugi- rugi energi ini menimbulkan hilangnya energi yang besar. Analisis buat memperoleh nilai rugi- rugi energi di jaringan transmisi 150 kV periset merancangan sistem aliran energi dengan memakai aplikasi ETAP 12. 6. Tata cara yang digunakan periset ialah mengambil informasi tegangan serta arus secara terus menerus sepanjang satu setiap hari penuh dikala terbentuknya beban puncak, pada jam 17. 00 serta jam 21. 00 Wib. Beban puncak rugi- rugi energi paling tinggi terjalin malam hari ialah pada 30 desember 2017 sebesar 0, 84 MW pada pembebanan 15% yang terjalin di GI langsa ke GI panton labu. Sebaliknya pada pembebanan 50% rugi– rugi energi sangat besar sebesar 0, 9452 MW terjalin pada GI langsa ke GI tualang cut. Beban puncak rugi- rugi energi paling tinggi terjalin sore hari serta malam hari pada 30 desember 2017 sebesar 1. 148 MW terjalin pada GI langsa ke GI pangkalan Brandan. Sebaliknya rugi- rugi energi terendah 0, 635 MW terjalin di GI langsa ke GI tualang cut. The power generation system and load centers are usually separated by hundreds or even thousands of kilometer, so the electricity generated must be distributed through the transmission network conductor. The source of electricity includes 3 stages such as the generation system, transmission and distribution network, thus creating obstacles in the process of distributing electricity. One of the obstacles is caused by the aspect of energy losses due to the distance between the generating center and the far load center. The effect of these energy losses results in a large energy loss. Analysis to obtain the value of energy losses in a 150 kV transmission network, researchers design an energy flow system using the ETAP 12 application. 6. The method used by researchers is to take voltage and current information continuously for one full day when peak loads are formed, at 17: 00 and at 21. 00 Wib. The peak load of the highest energy losses occurred at night was on December 30, 2017 of 0. 84 MW at a 15% load that occurred in the Langsa to the Panton Labu substation. On the other hand, at 50% loading, very large energy losses of 0. 9452 MW are intertwined from the Langsa substation to the tualang cut substation. The peak load of energy losses was highest in the afternoon and evening on December 30, 2017 of 1, 148 MW at the Langsa substation to the Pangkalan Brandan substation. On the other hand, the lowest energy losses of 0. 635 MW are intertwined in the Langsa substation to the tualang cut substation

Simple Design and Build Automatic Transfer Switch Generator Set On Airport Power Station With Failurea Indicator Protection

Electricity needs at airports are in dire need of backup and additional supplies apart from the main PLN source, such as generator sets. It is necessary to design a simple Automatic Transfer Switch that is connected to the main source operating failure indicator to a backup energy source. Research developed in order to provide benefits to airport operational management companies so that they are safe against energy needs in the event of an energy disturbance. Panel ATS is an abbreviation of the word Automatic Transfer switch, this tool serves to move the connection between one voltage source and another electrical voltage source automatically. The research was conducted by making ATS design. To ensure the design is appropriate and functioning properly, the panel tool is tested to function properly and can operate as desired. In carrying out the test, there are 3 ways, namely manual system testing on generator sets, manual system testing on modules and automatic systems. measurement data is carried out at the time of testing automatically as well as seeing the function of each component running well. The results of the design that have been made can be used as a backup energy source if the main energy source is disturbed or trouble shooting or in an emergency, even if the energy source can function when the airport is operating and does not interfere with airport operations. manual testing and automatic interchange switch can switch power sources to load with an average time of 4.09 seconds

Analysis of Age Transformer Due to Annual Load Growth in 20 kV Distribution Network

Distribution transformer is a component in distributing electricity from distribution substations to consumers. Damage to distribution transformers causes continuity of customer service to be disrupted (power cut or blackout occurs). The length of the PLN electricity network requires a transformer to distribute electricity to serve consumers and how to maintain the transformer. The daily load curve of a peak load for housing, shops and factories / industries varies. Load served 200 kVA distribution transformer cannot serve the load on housing, shops and factories / industry. The method used is the replacement of a distribution transformer with a capacity of one stage greater or the replacement of a distribution transformer with a capacity of two levels larger. The distribution transformer carried out by the research is a capacity of 200 kVA replaced by 250 kVA. The ability of a distribution transformer cannot accommodate a load which will increase as an area is advanced. Observations made by calculating the age of the transformer by assuming the annual load growth (r) = 3% = 0.3. Annual peak load (P) = 1.8 p, u increase in oil temperature at peak load (θo = 96.21 0C; 84.16 0C). The increase in the hottest temperature above the oil cover, the increase in the temperature of the hottest place above the oil (θg = 20 0C; 20 0C). The ratio of the load loss to the nominal load excitation loss (Q = 3; 30). By assuming the values of these methods it can be estimated that the life of a distribution transformer is 20 kV, a capacity of 200 kVA is 18 years

Evaluation and Modeling of Green Energy Consumption in North Sumatra, Indonesia

This paper discusses the level of green energy consumption in North Sumatra from 2020 to 2022 using the entropy method, the breakpoint method, and the integrated method. These three methods are applied to determine the feasibility of using new renewable energy. The three methods will be compared to each other to determine accuracy and options for analyzing models in the future. The level of green energy users from 2020 to 2022 generally shows a relatively stable and sustainable upward trend. During the 3 years there were fluctuations caused by the large growth rate of total energy consumption in North Sumatra, which increased by 6.35% from the previous year, and the level of urban green energy consumption grew steadily, which provided a more stable increase in user levels green energy with a sharp increase in the previous year. However, there are significant gaps in green energy consumption levels between cities. The contribution of this research is to select a model that will be applied in North Sumatra and provide input for policymakers regarding future energy and can have a positive impact on technological innovation, industry, and financial support in particular
