Abstract

Gangguan tegangan sag dapat merugikan hingga tujuh kali lipat dibandingkan dengankerugian yang timbul gangguan kualitas daya lainnya. Untuk meminimalisir gangguantegangan sag, maka didesain suatu sistem Dynamic Voltage Restorer. Prinsip kerja DynamicVoltage Restorer (DVR) yaitu mendeteksi tegangan sag menggunakan sensor tegangan ACdengan menggunakan metode pembagi tegangan 2 kapasitor dengan resistansi 330kΩ dan220Ω, kemudian di klamper sehingga tegangan menjadi DC. Sensor tegangan terhubungdengan ADC pada mikrokontroler ARM STM32F407VG yang digunakan untuk mengontrolinjeksi tegangan. Ketika terjadi tegangan sag, maka inverter menginjeksi tegangan DC darisumber kapasitor ke beban yang terkena gangguan dengan menggunakan boostertransformator yang dihubung seri dengan tegangan sumber dan beban induktif. Inverter 1 fasadikendalikan menggunakan logika fuzzy berbasis mikrokontroler untuk mendeteksi magnitudetegangan sag.Kata kunci: Dynamic Voltage Restorer, Fuzzy logic controller, Single Phase Inverter.

Abstract

To save energy nowadays is recommended to switch to renewable energy sources. In Indonesia, solar energy is abundant, so PLTS is made. The supply of PLTS is expected to reach maximum use. However, solar panels have many obstacles such as variations in temperature and sunlight intensity, MPPT systems are needed to find the maximum power point of the solar panels. Unfortunately, in Indonesia, the sunlight of short duration with the ideal irradiation time that can produce electricity from solar panels is 4 to 5 hours per day, so a PLN supply is still needed to support the continuity of the power supply. Because two sources are used, there is a problem where the load needs high continuity during power switching, so STS (Static Transfer Switch) is used for very fast power switching. Simulation results, when using EMR (Electromechanical Relay) the power transfer process takes 50ms or 5 cycles while STS takes 2ms or ¼ cycles. With very fast response to STS, sensitive equipment is kept safe from power quality disturbances such as voltage sag and voltage swell.

Abstract

DC motor speed regulation is an important role in the industrial process so it can run easily and efficiently. A good DC motor speed control system must have a fast and accurate response. However, it is rare to find a DC motor that has controlled to get a constant speed. This research presents an analytical comparison of PI controller and Fuzzy Logic Controller for Speed Control of DC Shunt Motor. The disadvantages of PI controller like it do not operate properly when the system has a high degree of load disturbances [1]. FLC is a good for load disturbances and can be easily implemented. The simulation of both speed controller have been made by Matlab Simulink software.Keywords: DC shunt motor, fuzzy logic control, matlab, PI control, simulink.

Abstract

Automatic transfer switch-Automatic main failure is a commonly used technology for shifting supply from PLN to a generator in the case of a PLN blackout. The ATS-AMF module system frequently employs a PLC, which comes at a high cost, and the system alarm information only is seen by the user close to the system. The purpose of this research is to design an automatic transfer switch-automatic main failure system that used SCADA to improve the reliability of electricity supply by providing notification alarm information and buzzers. This research contribution is a development of an automatic transfer switch-automatic main failure, which can be used as a simulator for studies on measuring voltage, current, power, and frequency of main power supply in real cases. Furthermore, this instrument is used fuel level and temperature measures for its backup power (Genset), the result of measures will be monitored SCADA system with the available failure data, alarm logs, and status logs recorded in historical data, which is designed at a low cost and is easy to use. This information result of the measured sensor will be transferred in real-time to the SCADA system, so can be directly obtained for analysis. The main components for this system are microcontroller STM32 Nucleo, PZEM 004T sensor, ultrasonic sensor, DS18B20 sensor, ethernet, and VTSCADA. The result of this system is the temperature detects 89oC, and alarm information has been sounded with the statement “Genset Temperature Warning HIGH” thus instructing the generator to turn off the system. Meanwhile, based on the results of the fuel adjustment test, SCADA gives the information “Genset Fuel Level Warning LOW” when setting the fuel at 36%. The data historical viewer that stores up to 6 months and alarm information for the warning system on the SCADA has been successfully designed.

Abstract

The protection system against disturbances in induction motors has an important role in industry. In general, protection in electrical installations only uses MCB (Miniature Circuit Breaker) and fuses which can only protect against overcurrent and short circuits and there are still many kinds of important protection that have not been covered in it even though along with technological developments many electronic protection devices have been created. The purpose of this final project is to plan and manufacture electronic motor relays against over load, phase loss, phase reverse, phase unbalance, short circuit, ground fault, and locked rotor disturbances. The AVR microcontroller is used as a controller for all systems in detecting disturbances. Where the current setting range and trip time are programmed using the C language which is operated with a keypad and displayed on the LCD. As current and voltage sensing using current transformers and voltage transformers. As for sensing phase reverse, it takes the signal from the differential amplifier and forwards it to zero crossing, trigger and X-or. Testing the accuracy of the electronic motor relay is carried out in each fault. The data obtained shows that the microcontroller can be used as a precision analog voltage controller. This is because the AVR microcontroller has good features and is supported by adequate processor speed for use in this kind of application.

Abstract

The efficiency of electrical power can be improved by improving power quality. Installing capacitor banks is one way to improve power quality by improving the power factor. On the other hand, the use of non-linear loads is increasing. This load produces a non-sinusoidal waveform which causes harmonics to appear in the electric power system. Harmonic problems will become a serious problem in the power system when there is a capacitor bank in the system which will cause resonance risk at the harmonic frequencies. This resonance problem can be solved by installing a detuned filter. Detuned filters can reduce harmonics and protect the system from the resonance risk. However, the detuned filter installation is not sufficient to reduce all harmonics that generated by non-linear loads, so the system needs to be equipped with an active filter. In this study, using a combination of 14% detuned filter and active filter, each of which is attached parallel to the load. The result of power quality improvement can increase the power factor from 0.6 to 0.88, THDi is reduced from 49.5% to 18%, and THDv is reduced from 2.18% to 1.97% after installing the hybrid filter

Abstract

Penggunaan sumber daya minyak bumi dan secara terus-menerus dapat menyebabkan cadangan sumber daya tersebut semakin menipis. Oleh karena itu, sesuai dengan arahan Kementerian Energi dan Sumber Daya Mineral (ESDM) diperlukan suatu teknologi untuk meningkatkan elektrifikasi dan konsumsi listrik terutama dalam kebutuhan rumah tangga,salah satunya kompor induksi. Kompor induksi sudah mulai banyak digunakan, tetapi bisa dikatakan masih belum fleksibel dan kompatibel. Sehingga, diperlukan kompor induksi yang dapat digunakan kapan pun dan di mana pun. Diperlukannya sebuah kompor induksi yang demikian, dikarenakan pentingnya para bayi untuk mengonsumsi Makanan Pendamping Air Susu Ibu (MPASI) pada kondisi yang konstan dan stabil terhadap suhu di lingkungan sekitar yang sangat bervariasi sehingga nutrisi bayi dapat terjaga dan terpenuhi dengan baik. Sistem ini dirancang menggunakan input tegangan 220 VAC yang kemudian diturunkan menjadi 36 VAC menggunakan transformator dengan tujuan agar arus pada sistem yang nantinya masuk ke inverter tidak terlalu besar. Terdapat lilitan induktor pada rangkaian resonansi seri yang menghasilkan medan listrik dengan frekuensi resonansi 40 kHz dan menginduksi logam sehingga menghasilkan panas pada logam. Fuzzy Logic Controller (FLC) digunakan untuk mengontrol kecepatan menuju set point suhu MPASI.
