Abstract

Penyandang tuna netra memiliki kondisi fisik yang terbatas. Kondisi fisik ini membuat penyandang menggunakan tongkat sebagai alat pemandu dalam kegiatan sehari-hari. Kemajuan teknologi membantu penyandang mengganti tongkat dengan alat pemandu menggunakan sensor ultrasonik sehingga lebih leluasa bergerak. Sensor ultrasonik bekerja dengan memanfaatkan gelombang ultrasonik sebagai pemancar dan menghitung jarak dengan perbedaan selisih waktu. Kepekaan sensor ultrasonik dari 2 cm sampai 200 cm. Pengolah data yang digunakan adalah mikrokontroler arduino dan keluaran berupa motor getar. Alat pemandu tuna netra menggunakan sabuk sebagai desain utama. Sensor diletakkan pada sisi kiri, depan, dan kanan sabuk untuk mendeteksi benda yang berada pada jarak pantulan sensor. Motor getar diletakkan pada samping sensor untuk memberikan getaran ketika sensor ultrasonik aktif. Alat pemandu tuna netra mempunyai spesifikasi dalam mendeteksi jarak 30 cm di kiri sabuk, 150 cm di depan sabuk, 30 cm di kanan sabuk dan 120 cm – 125 cm di bawah sabuk.

Abstract

Short circuit causing over current problem and can might causing interference of the equipment performance such as distribution transformers also causing widespread disruption occurred. In resolving such interference is required as protection system on the distribution system. Seeing all above is needed coordination between the supporting component of the protection system which is consisted of Over Current Relay (OCR) and Ground Fault Relay (GFR). The research was conducted at PT. PLN (Persero) South Bali Area Network, INDONESIA on recloser in the feeder line of Penebel. OCR setting between the Relay feeder of Penebel, Recloser Celagi, Recloser Bakisan, and Recloser Benana still less selective, with time value coordination between average security was still less than 0,2 second. Then OCR setting and GFR relay feeder of Penebel, Recloser Celagi, Recloser Bakisan, and Recloser Benana was recommended for re-setting in order to minimize disruption and electric power distribution system to be reliable.

Abstract

The environmental impacts due to technology applications have been an interesting issue for researchers and engineers worldwide. Innovations in development of environmentally friendly technology have been implemented to minimise severe consequences of the impacts, including in electricity generation technology. It has been known that the use of fossil fuel will increase the emission of greenhouse gasses, such as SO2, NO and CO2. A strong regulation for emission of greenhouse gasses has imposed a great extent of efforts in reducing the emitted gases. At present, the electricity need for Penida island is mainly generated using diesel generating system. The use of large amount of diesel oil for electricity generation certainly increases the emitted greenhouse gasses. This paper discusses an alternative technology in wind energy utilisation for electricity generation at Penida Island. The position of Penida island, which is in the ocean front region, yields a high potential use of wind energy for electricity generation. The analysis results show that at the Penida Island, the electricity may be produced with a maximum power of 50kW from a single wind turbine. In order to fulfil the total electrical energy need for the island, it is required to develop hundreds of turbines. Development of this amount of wind turbines certainly produces other related environmental impacts, such as ecological impacts, visual aesthetics and generated noises.

Abstract

Modern electric power system that many its dynamic equipment continuously vulnerable to internal and external disturbances. On the condition of the disorder, it often happen oscillation in each part or between parts of the electrical system is interconnected. These oscillations become a major problem for the stability of the power system. Modern electrical control systems require a sustainable balance between power generation and demand varying loads. Power System Stabilizer and Static Var Compensator is a control device that is used to dampen low frequency oscillations and to provide additional feedback signal to stabilize the system. To increase the damping, system equipped with PSS generator that provides additional feedback to stabilize the signal in the excitation system. It is generally that the machine parameters changed by the load, so the dynamic behavior of the different machines at different operating conditions. Design PIDPSS3B power system stabilizer and PIDSVC controller used aim to get performance and optimum damping. Design and optimization of the proposed has the ability to optimally dampen and suppress errors are minimal.

Abstract

The design of balancing the load current on three-phase systems using a microcontroller ATMega 2560 is a tool that serves to reduce the power loss. Power loss due to the load current unbalance the current flows in the neutral phase on three-phase systems. Current flows in the neutral phase distribution transformer into a detriment to PT. PLN (Persero) for the power lost to the earth and can not be used by consumers. So that it will balanced the load current to reduce the value of neutral current. The tool is also equipped with a monitoring system that displays current magnitude of each phase including the neutral phase.The methods in making this tool is divided into two parts: first, the design of hardware consist of designing electronic components which are used by the current sensor circuits, relay, LCD (Liquid Crystal Display) etc. Second, the design of software is a tool listing program procedure including the monitoring program displays the current of each phase on LCD using the Arduino IDE. SCT013-030 current sensor used, the output of the current sensor is connected to the pin ADC (Analog to Digital Converter) microcontroller ATMega 2560. Then microcontroller process the data and generate a current value displayed on the LCD. The other result of processing current value is a command to enable or disable the relay that connects three-phase resource with single-phase loads.The result of the test design of balancing load current on three-phase system using a microcontroller ATMega 2560 succeed balancing the load current by moving the channel load of sequence number load the smallest connected to the phase with the current biggest load toward a phase that has a load current smallest when neutral current exceeds the limit is permitted. In this situation, the neutral current will not be possible be zero. In fact, the maximum current value for the neutral phase for PT. PLN (Persero) 50 amperes calibrated to 1 ampere and is used as a limit on this prototype. If the neutral current on LCD monitor exceeds 1 ampere, then there will be balancing of the load current. The current sensor measurement results are displayed on a monitoring approach measurement result using pliers ampere.
