Model Tegangan Konstan Dari Pembangkit Listrik Tenaga Angin Kecepatan Variabel Yang Berbasis SCIG Untuk Analisis Aliran Daya

Belakangan ini, aplikasi pembangkit listrik tenaga angin (PLTAn) kecepatan variabel semakin populer dan telah melampaui penggunaan PLTAn kecepatan tetap. Kepopuleran ini terutama disebabkan karena PLTAn kecepatan variabel jauh lebih efisien dalam menangkap atau mengekstraksi energi angin dibandingkan PLTAn kecepatan tetap. Salah satu jenis PLTAn kecepatan variabel yang saat ini penggunaannya semakin meningkat karena biayanya yang relatif lebih murah adalah PLTAn kecepatan variabel yang berbasis SCIG (Squirrel Cage Induction Generator). PLTAn jenis ini biasanya dilengkapi dengan konverter elektronika daya untuk memperoleh rentang operasi kecepatan variabel yang lebih lebar. Agar dapat melakukan analisis dari suatu sistem tenaga listrik (termasuk analisis aliran daya), pemodelan komponen-komponen sistem tersebut sangat diperlukan. Makalah ini membahas model keadaan mantap PLTAn kecepatan variabel yang berbasis SCIG untuk analisis aliran daya sistem distribusi tenaga listrik. Model yang diusulkan ini dapat digunakan pada PLTAn kecepatan variabel berbasis SCIG dengan mode operasi kontrol tegangan. Model tersebut dikembangkan berdasarkan rumus-rumus yang menghitung input daya mekanik turbin dan output daya listrik PLTAn. Makalah ini juga membahas studi kasus dimana pada studi tersebut dilakukan penyelidikan tentang aplikasi dari usulan model pada suatu sistem distribusi tenaga listrik

Analisa Mesin Pengering Makanan Food Dehidrator Menggunakan Sensor Thermostat Berbasis Hybrid

The process of drying food is done in the traditional way, by drying it in the hot sun, but the traditional drying method makes the food unhygienic. Several factors can influence the drying results of food ingredients, including temperature and drying time. Using optimal drying temperatures and times can reduce the level of damage caused by the drying process. This research aims to obtain an analysis of a food dehydrator drying machine using a hybrid-based thermostat sensor that can optimally condition the temperature and time factors in the drying process, the hyfood dehydrator machine system uses a dehumidification method, there is a heat recovery mechanism that recycles heat to open new air, thus saving 60-70% of fresh air preheating energy consumption. Hot air moving in the room dries the material. It is known that the test result data was analyzed by calculating the accuracy values, down to the relative distance values. The results of the comparison process are used as validation of the output values ​​produced by the temperature measuring instrument. The measurement results of the Digital Thermostat Sensor are in accordance with the datasheet and have a high level of accuracy. So the Digital Thermostat Sensor measuring instrument can be used as a measurement tool. With an internal fan, thermostat, and time settings on this device, you only need to set the right heat according to the type of food you want to dry. The shelves in the cupboard consist of drying trays that can maximize the drying proces

Perbandingan Performansi Antara Differential Evolution dan Bat Algorithm pada Tuning PID Untuk Optimasi Kontrol Kecepatan Paralell Hybrid Electric Vehicle

In the last decade, there have been many means of transportation that use fuel oil (Internal Combustion Engine (ICE)). This has a serious impact on the environment due to the emission of pollutant gases. One solution is the use of a hybrid electric vehicle (HEV) as a substitute for vehicles that use ICE. One of the performance that must be owned by the HEV is to have a stable speed when driving. In this study, several methods used in the metaheuristic algorithm in the disturbance observer have the advantage of describing the inverse model of the plant without making a mathematical model. The test is carried out by comparing the two methods of the metaheuristic algorithm, namely Differential Evolution and Bat Algirthm. The simulation results show that the method used in this HEV is to maintain its speed, so according to the test results it shows that the Differential Evolution method is the best method for controlling the speed of the Parallel Hybrid Electric Vehicle

Analisis Kelayakan Ekonomi dan Self-Consumption dari PLTS On-grid dan Hibrid Kapasitas 1328 kWp

Abstract — Solar energy is an alternative energy source to meet electrical energy needs. In Indonesia, rooftop solar power plants (PLTS) are widely used to meet people's electrical energy needs. However, the government's policy of limiting the use of solar energy from rooftop PLTS to serve electricity loads in the industrial sector and not allowing energy exports to the public electricity network (grid) means that households and producers providing electrical energy (prosumers) must maximize their own consumption (self-consumption) from solar energy and consider the economic feasibility of installing rooftop solar power plants. This paper aims to analyse the economic feasibility and independent consumption of on-grid and hybrid type rooftop PLTS both with 15% load and with actual load. The case study used is a PLTS with a capacity of 1,328.29 kWp with electricity load and solar panel production for two months used as a pattern for electricity load and solar panel production for a year. Economic feasibility is analysed by calculating economic feasibility parameters for the two types of rooftop PLTS, including net present value (NPV), internal rate return (IRR), profitable index (PI) and payback period (PBP). The simulation is carried out by programming using the Python programming language. The simulation results show that the level of self-consumption is greater when the electricity load served is greater and also when using batteries (hybrid PLTS). The greater the self-consumption value, the greater the economic feasibility of the rooftop PLTS to be built. Overall, on-grid rooftop solar PV is more economically feasible to install. Keywords — On-grid, hybrid, economic feasibility, self-consumption, rooftop solar power plant

Pengaruh Panjang Jaringan Terhadap Drop Tegangan Pada Penyulang Duku dan Kurma PT. PLN (Persero) ULP Rumbia

Voltage drops in distribution systems can occur in medium voltage networks (JTM), distribution transformers, low voltage networks (JTR) and house lines. Voltage drops in the network cause suboptimal distribution and increase power losses. PT. PLN (Persero) ULP Rumbia has two feeders with pure radial network characteristics sourced from the Seputih Banyak Main Substation. The length of the Duku Feeder network has a voltage of 96.8 KMS with a load of 150 A while the length of the Kurma Feeder network is 207.21 kV with a load of 155 A. The network reconfiguration of the Dente Teladas Substation was carried out to shorten the network length. This research aims to calculate the voltage drop that occurs at the Duku and Kurma feeders before and after network configuration. This research uses the quantity method to compare the calculation results with the voltage drop standards set by PT. PLN (Persero). After reconfiguring the Duku and Kurma feeders, there was an increase in tip voltage which indicated improvement. From the calculation results before adding the network to the Duku feeder, the voltage at the receiving end was 19.5 kV with a voltage drop of 7.1%, and at the Kurma feeder the voltage at the end of the line was 17 kV with a voltage drop of 19%. This is clearly no longer in accordance with the local TMP, and requires further study to overcome this problem. The voltage on the two feeders goes through a step up process using a Medium Voltage OLTC (On Load Tap Changer) so that the voltage on each feeder becomes between 19.86 kV to 20.16 kV
