Abstract

Wind turbines function as producers of mechanical power to drive generators in wind power plants. One factor that needs to be considered in the operation of wind turbines is the maximum capacity of the generator. Wind turbines must operate below the generator rating so as not to cause damage to the generator. Therefore, the operation of the wind turbine needs to be monitored and controlled to keep it operating within the generator rating limits. In this paper a horizontal axis wind turbine monitoring sistem is proposed using an Android smartphone. Wind turbine monitoring includes wind speed and turbine rotation speed parameters. This parameter data is obtained from sensors that are processed with Arduino Mega 2560. Data from Arduino is sent via the Bluetooth HC-04 module to be displayed on an Android smartphone. The experimental results show that the proposed wind turbine monitoring system has worked well. This can be seen from the wind speed and turbine rotation data that is displayed on android is exactly the same as the data on the measuring instrument

Abstract

Energi listrik yang dihasilkan dari sebuah pembangkit akan disalurkan pada sebuah subsistem yang dinamakan dengan single machine infinite bus, tetapi gangguan pada sistem single machine infinite bus seperti perubahan beban secara acak pada sisi pembangkit dapat mengakitbatkan kestabilan sistem berubah sehingga sistem single machine infinite bus tidak berjalan normal. Artikel ini bertujuan untuk menganalisis kestabilan dinamik pada sistem single machine infinite bus menggunakan kontrol power system stabilizer dan kontrol propotional integral derivative.  Metode kepustakaan diterapkan untuk menganalisis data dan parameter single machine infinite bus yang disimulasikan menggunakan software matlab v. R2020a. Hasil analisis kestabilan dinamik sistem single machine infinite bus pada perubahan sudut rotor secara keseluruhan setelah memberikan gangguan dinamik sebesar 0.013 p.u dengan menambahkan PSS dapat meredam 0.068 osilasi pada sudut rotor yaitu ketika sudut rotor berada pada titik 0.359 p.u menjadi 0.291 p.u dan pengurangan waktu yang singnifikan juga terjadi pada sistem ini sebesar 7.3 detik serta meredam overshoot dari nilai 38.19% menjadi 2.57% serta dapat meredam 0.000115 osilasi pada frekuensi yaitu ketika frekuensi berada pada titik 0.000329 p.u menjadi 0.000214 p.u dan pengurangan waktu yang singnifikan juga terjadi pada sistem ini sebesar 4.2 detik serta meredam overshoot dari nilai 55.58% menjadi 0.57%. Penambahan kontrol propotional integral derivative pada sistem single machine infinite bus yang dilengkapi power system stabilizer memberikan hasil yang sangat baik dalam meredam osilasi sudut rotor dan frekuensi yang dilihat dari hasil pengukuran dapat meredam 0.073 p.u pada sudut rotor dan 0.000176 pada perubahan frekuensi dan meredam overshoot dari 55.58% menjadi 0.50%.

Abstract

DC motor is one type of electric motor that is widely used in industry to support the production process. The DC motor speed must be controlled so that it operates in accordance with the desired speed. In this paper, The DC motor control system is proposed using an one quadrant DC chopper based on proportional Integral (PI) controller. The control system is implemented using the arduino mega 2560 microcontroller, which is programmed through Matlab Simulink. Control system devices is also equipped with a keypad for input speed reference and LCD for displaying the speed data. The proposed design in this study was verified through experiments in a laboratory with varying rotor speeds. The experimental results show that the design of a DC motor control system using an one quadran DC chopper based PI controller has worked in accordance with the objectives. This can be seen from the speed response of the motor that operating in accordance with the reference speed inputted via the keypad.

Abstract

Solar power plants are a type of electricity generation from renewable energy sources that are widely developed in Indonesia. The power produced by solar power plants is determined by the temperature and radiation from the sun hitting the surface of the solar panels. The greater the solar radiation on the solar panels, the greater the power produced by the solar panels. The maximum radiation of sunlight can be obtained if the surface of the solar panels is perpendicular to the position of the sun. Therefore, the surface of the solar panel needs to be controlled to match the position of the sun which is always moving. This paper proposes time-based tracking of the sun's position without sensors. Solar tracking system (solar tracker) is implemented with Arduino and Real Time Clock (RTC) DS 3231 as a timer. The test results show that the proposed solar tracker has worked well, where the position of the solar panels can follow the movement of the sun

Abstract

Motorcycle pedicab is one of the land transportation vehicles that are still widely used by the community, especially for short distances. One of the disadvantages of using a motorcycle pedicab for transportation is the unavailability of standard fare for passengers. In this paper, a taximeter is proposed to determine motorcycle pedicab rates based on distance traveled. The taximeter display in the form of mileage and rate is designed using the Android application and Arduino Uno as data processing. This device is equipped with a hall effect sensor as a reader of wheel rotation and a bluetooth module as the interface between Android and Arduino. In addition, the Android screen also provides a start and stop button to start or stop the calculation of the meter. The experimental results show that this devices have worked in accordance with the objectives, where the android screen has been able to display distance data and pedicab rates according to mileage.
