Abstract

Distorting of energy of tension DC to AC used to support the social life of society. There by will arise an problems form of electric current from PLN desisted sudden and long time. The problems of course can be disregarded with the installation of power plant byself like generator AC or use the accumulator. Using of transistor energy of type MOSFET also used especially at final of switching showing optimal performance. This matter is showing with the temperature speed which relative lower and ideal performance temperature stability. The result of comparison of output power and efficiency of changer of energy of tension DC to AC with the transformator non-CT indicate that the appliance can only work 90% from maximal appliance ability. This problems because of accumulator use ably small current or standart.

Abstract

Listrik merupakan salah satu kebutuhan penunjang yang sangat penting bagi kelangsungan hidup manusia. Dari aspek paling sederhana sampai ke proses penting yang melibatkan pembuatan alat-alat pendukung kehidupan manusia, keseluruhan proses-proses tersebut memerlukan tenaga listrik. Permasalahan yang timbul dengan adanya kebutuhan listrik yang bersifat kontinyu akan terjadi pada saat pembangkit tenaga utama mengalami kerusakan atau kegagalan operasi. Penelitian ini merancang suatu prototipe dari sebuah sistim otomatis yang dikendalikan oleh mikrokontroler. Dengan metode pengaturan ini, sistem pensaklaran tegangan 220Vac dari PLN dan 220Vac keluaran DC to AC converter (pengganti genset) dapat dikendalikan menggunakan master switch secara otomatis. Selain itu proses stater dan mematikan kembali juga dapat dikendalikan secara otomatis. Hasil pengujian dan analisis yang telah dilakukan menunjukkan bahwa pengaturan motor stater dan choke selenoid genset menggunakan mikrokontroler terbukti dapat dilakukan termasuk pengaturan proses stater dan mematikan genset secara otomatis. Sistem akan tetap stabil dan akurat selama DC to AC converter (pengganti genset) dan batere yang digunakan berada dalam kondisi prima. Persyaratan ini mutlak harus diperhatikan agar proses stater genset tidak terlalu lama dan genset mudah dimatikan hanya dengan menutup choke.

Abstract

An Induction motor is an electric machine that converts electrical energy into kinetics energy and widely used in the industrial fields. Many disturbances that occur in the motor that cause production to be not optimal as for the problems that occur at PT. Madu Baru Yogyakarta is when there is a disturbance in the three-phase induction motor, workers still use manual methods to analyze the disturbance, so that the time used in the analysis takes a long time even the three-phase induction motor cannot work again. In overcoming this, it is necessary to implement a data logger system that can detect the electrical parameters of a three-phase induction motor in real time, in order to make it easier to analyze existing disturbances through graphs. The voltage sensor CYVS13-34U0 and current sensor SCT-019 will detect the electrical parameters which will then be processed by the Arduino Mega 2560 pro so that the processed data will be stored on the microsd card. The data resulting from the processing are electrical parameters in the form of voltage, current, apparent power, real power, reactive power, and power factor. The data will be saved as a file with .txt format which has an interval of about 1 minute for each storage.

Abstract

Synchronous generators work by changing mechanical energy into 1 and 3 phase electrical energy. Reactive power is needed by consumers to generate magnetic fields in inductive electrical loads. The reactive power setting can be adjusted by increasing or decreasing the excitation current. Excitation current is a DC electric current that is supplied to the generator rotor to generate a magnetic field. The excitation current is proportional to the reactive power released by the generator. This is indicated by the increase in the reactive power of the generator which was initially valued at 0.6999 MVAR to 0.7655VAR after the excitation current was increased from 0.130 kA to 0.140 kA. The data used is measurement data per day from July 1 to July 14, 2022. Calculation of reactive power using the power triangle formula has results that are close to the values of reactive power measured by the largest difference of 0.0198 MVAR or 2.8637547%. The reactive power is all positive so the state of the generator is lagging. The output voltage tends to be stable near the nominal voltage of 6.3 kV, this is because the increase and decrease in excitation is intended to keep the generator output voltage stable.

Abstract

Industry is one of the largest users of reactive power in the distribution of electric power. Industries use equipment such as induction motors, transformers and other equipment to support their production needs. Loads such as induction motors are inductive loads that require reactive power to operate. Reactive power in an electric power distribution network is a loss. Reactive power can reduce the effectiveness of the real power which is converted into active power so that the efficiency of real power usage is reduced. Installing a capacitor bank is one way to compensate for the use of reactive power in a load. Installing capacitor banks aims to improve the value of the power factor that has decreased due to the use of excessive reactive power loads. PLN has set a standard power factor value for consumers of 0.85 and reactive power consumption of 0.62 of the total power consumption. For this reason, it is necessary to carry out further analysis regarding the advantages and disadvantages of installing bank capacitors to improve the value of the power factor so that the ideal economic factor for consumers is obtained.

Abstract

For lovers of the outdoors and looking for tranquility, the Puthuk Ngepoh tourist attraction is located in Brajan Hamlet, Banjararum, Kalibawang Kulon Progo, which is in the Menoreh Hills. The location is 45 km from downtown Jogjakarta. Managed by a tourism awareness group (POKDARWIS), it can be a choice of destination to fill the weekend. One of the existing problems, is the constraint on electricity which is more economical. Therefore, the authors seek to Install Solar Panels (PLTS), as an alternative source of electricity by utilizing sunlight as a producer of electrical energy, which is environmentally friendly. This is expected to be a solution for the burden of lighting at tourist sites. Batteries are one option to store electrical energy, from solar panels. In observations, the battery is charged by solar panels that generate voltage by converting solar energy into electrical energy. The voltage generated from the solar panels ranges from 14.8 to 17.5 volts DC. The solar panels used are of the type Polycrystalline (Poly-crystalline) with a power of 100wp. The measurement results show that the solar panel current and voltage are ± 17V, the distribution to the battery is regulated by the solar charger controller (SCC), an average of 13.5V. Change the DC to AC voltage using an inverter. This shows that after the battery is charged for 2-3 hours, it can operate for 3 hours with an inverter output voltage of 220-176volt AC. Voltage and current will start to increase at 07.00 WIB, maximum at 10.00-13.00 WIB, starting to decrease until the afternoon.

Abstract

Ship's Ferries are a sea crossing that continues to operate around the time. The consequence related to shipping activities is an increase in ship exhaust emissions. One alternative for ship propulsion that is environmentally friendly is the Flettner rotor. The working principle of the tool follows the theory of the Magnus effect, where the force arises due to the difference in pressure between the two sides of the Flettner rotor. This study implicates the Flettner rotor on the Kalianget-Kangean ferry route with variations in wind speeds of 10, 15 and 20 knots and variations in dimensions of 3x1, 5x1 and 7x1 meters with a rotational speed of 500 rpm. Optimal results through computational fluid dynamics (CFD) simulations show a coefficient of lift (CL) of 3.647 and a lift force (Fl) of 2,980,631.2 kilonewton with dimensions of 5x1 meters and a wind speed of 15 knots. While the implicit percentage of Flettner rotors in KMP. DBS I of 18.11%, KMP. DBS III of 11.27%, and KMP. NS 92 of 5.45%.
