Abstract

Small and medium-scale plants connected to the distribution line form a distributed generation (DG) system. Unsynchronized reclosing, due to the operation of a recloser, is an important issue in DG systems. In this paper, simulations of typical DG system are performed to show the effect of unsynchronized reclosing. The simulation results show that unsynchronized reclosing causes the generator to experience over speed, over and under voltage, and over current, which can damage or reduce the life of the generator. A permanent short circuit that causes the contact of recloser to open and close repeatedly has a worse effect than a temporary short circuit. Opening the circuit breaker at point of common coupling with the installation of dummy load can reduce the bad effect of unsynchronized reclosing.

Abstract

Inverter as one equipment relates closely to the renewable energy sector gain more and more important role in utilizing renewable energy widely. The inverter converts dc to ac form by a specific switching strategy. In this research, the switching strategy employed unipolar sinusoidal pulse width modulation (SPWM). The switching schemes were obtained by synthesis from sine lookup table that the width of pulses were obtained from simulation of PSIM. The aim of this research is to create a switching scheme in a software and then implemented in16-bit digital signal controller (DSC). Experiment in lab scale has been done to verify the proposed unipolar SPWM. The results showed that SPWM signals were easier generated in 16-bit digital signal controller (DSC). Other that, feature of PWM in this DSC has been supporting in inserting dead-time to avoid shoot through current at IGBT.

Abstract

Recently, Microhydro Power Center (Pusat Listrik Tenaga Mikrohidro or PLTMh) has been spread widely the energy electric generator. PLTMh control system in Indonesia often uses automatic control system. One of the reasons for this is that the operation and monitoring of the PLTMh could be done from a distance. One of PLTMh models of remote control is known as SCADA. One of the main parts of SCADA is Master Station (MS), Remote Terminal Unit (RTU) & Communication System. Communication System in SCADA can be built in several choices: wired or wireless. Remote control can be built using Wireless Sensor Network (WSN) system. The application of WSN in operating SCADA could ease installation and increase communication reliability. This study applied ZigBee technology on PLTMh SCADA control data communication. ZigBee was chosen because it’s free of operation and licensing charge, had OSI feature and low cost, those are reasons why they are best suited to PLTMh application. In the application, ZigBee hardware was divided into several parts: Coordinator on Master Station(MS) (one unit), End Devices which were each RTU unit point (two units) and Router as a data hooping between Coordinator & End Device (one unit). The furthest point between Coordinator and End Device through Router could reach 645 meters. This was tested in LOS (Line of Sight) condition. RSSI signal on ZigBee was used to see the strength of signal reception on Coordinator as data collector. RSSI score (-dBm) became smaller at maximum distance variation. This meant signal power at data jump point became lower. ZigBee based data communication to form SCADA network had been built well in join a network model, which was between Coordinator — Router — End Device at the furthest distance, 645 meters, with signal power of -82dBm.

Abstract

Renewable energy source likes solar panel and wind turbine have intermittent character from instability power source generated. The instability power source can make dip voltage in power grid which happen in half cycle until few seconds. To stabilize the voltage in power grid from dip voltage, some methods have been developed using power electronics technology like VSI inverter, STATCOM, energy storage, OLTC, and MERS. The power electronic circuits have some advantages, such as small dimensional size and lightweight to keep voltage in power grid. In this paper, the MERS circuit was applied in induction motor which has small full bridge circuit, uncomplexity computation, and low switching frequency, so it needs low end hardware requirement. This paper proposed the use of MERS dc capacitor with 50% value from induction motor resistance. The result shows that MERS has advantage and can keep the voltage in power grid when the voltage below 39% and 15% above rated voltage (220 Vrms) with the recovery time around 0.3 second and keep the dip voltage over 1 second.

Abstract

Basically, commutation process in a brushless DC motor needs rotor position information. However, to reduce production cost, in some specific applications such as fan or pump, the position sensors are not installed. It is possible to extract the rotor position through observing back emf signal available on the motor terminals. In this paper, implementation of a simple sensorless commutation controller algorithm for a BLDC motor is presented. The algorithm is implemented in a 16-bit digital signal processor (DSC). Experiment has shown that it produces correct timing signal to control BLDC motor from 1280 rpm up to over 3000 rpm.
