Abstract

Transient stability is an important aspect in maintaining the continuity and reliability of the electrical power system when a sudden large disturbance occurs. However, there is a time operation's limitation of the protection system to eliminate disturbance before the system becomes unstable and loses its synchronization. Critical Clearing Time (CCT) is the toleration time to eliminate the fault to keep the system stable. To improve system stability, installing Supercapacitor Energy Storage (SCES) can be one of the methods for extending the CCT values. SCES absorb large amounts of electricity simultaneously when a fault occurs. This paper proposed a determination of SCES' controller effect in extending the CCT. SCES becomes a dummy load and extends the CCT value depending on the controller's ability to respond to a fault. Controller modeling is applied to SCES, which is installed at the bus generator with determined capacity. The modified Fouad and Anderson 9-bus 3-machine system with a single machine to an infinite bus is used to validate the proposed method. Moreover, the critical trajectory method, which is known as a faster calculation and better accuracy than the time domain simulation method, is used to obtain the CCT value. The result shows that the faster controllers work against fault, the higher the CCT value improvement of system CCT. The highest improvement occurs when the controller works at 0.001s.

Abstract

A The use of LCD projector as one of the supports media for teaching, and learning activity has been commonplace in the world of education today, for example at the University of Trunojoyo Madura. During this time, the LCD projector is very helpful in the learning process, especially for presentations and others. The LCD projector also very well utilized with the limitations of the remote, often the projector must be turned on manually, by hand or by using a long stick. For a long time, if this continues and is often done it can cause damage to the projector and can disrupt the teaching and learn process in the room. The solution in this case is to make a simulation tool and projector controller application that functions to turn on, turn off, kmow the slope and adjust the direction of movement on the projector. Furthermore, this application can be embedded on mobile devices, especially Android-based mobile phones. This tool uses the Bluetooth module, Arduino as a media connection between Android and Arduino. With the use of the application, it is expected to be implemented to avoid damage to the projector which is too often used manually and certainly will greatly assist the teaching and learn process, especially at the University of Trunojoyo, Madura.

Abstract

Radial distribution network configuration is difficult to simplify because it is very complex. This network reconfiguration is used to redesign the configuration form of the radial distribution network by opening and closing switches on the distribution network. Purwoasri feeders, Rayon Kertosono, Mojokerto area have very large losses that need to be reconfigured. The resulting power flow will produce a network power loss as a result of the configuration. The reconfiguration process will be repeated until the configuration form that produces the smallest power loss is obtained. The number of feeders and buses on the network will be difficult if done with manual calculations and requires a very long time, so solving the problem must use a computer program. Network reconfiguration using the Matlab 2013a program will analyze its power flow using the Newton Raphson method and using the artificial intelligence method, Modified Imperialist Competitive Algorithms (MICA). With this method, it was obtained before the reconfiguration of the network suffered a loss of 89,724 kWatt after the reconfiguration had a loss of 54.8299 kWatt. The results of reconfiguration can reduce losses of 0.6173 kWatt or 38.95688%.

Abstract

The system can maintain its synchronization under a transient condition. The transient stability system can be evaluated using the critical trajectory method by calculating the Critical Clearing Time (CCT). The advantage of using a critical trajectory method is that the CCT can be found directly and more accurate than the time domain simulation method. This paper proposed the addition of Supercapacitor Energy Storage (SCES) and damping to enhance the transient stability on multi machine system. SCES is an electrical energy storage device that quickly stores and supplies large amounts of electricity, while damper winding damp the oscillations during unstable steady state conditions. Within the addition of SCES and damping in the system, the stability will last longer than before. The stability system is seen by the extended CCT. Furthermore, multi-machine to infinite bus used to validate the proposed method. The test system also includes the Automatic Voltage Regulator (AVR) and the governor

Abstract

The distribution of electrical energy from the power plant is not always available all the time. This is due to disturbances that occur in the power plant, transmission line and distribution channel. So that consumers who need electrical energy guarantees always need a backup source of electrical energy, in this case a generator set that has sufficient capacity to bear all the required loads. However, the generator set as backup energy will cause the voltage to become unstable. To find out how stable the reserve energy voltage is, a voltage stabilizer system is needed. This research produces a Voltage Stabilizer using a frequency sensor. The voltage stabilizer uses the ZMPT101B voltage sensor. When the main supply (PLN) is interrupted or disconnected, this sensor will give a signal to Arduino, and Arduino will command the Generator set to start. This change is also controlled using an Automatic Transfer Switch (ATS) and can be observed from the frequency value monitored by Delphy and results in an acquired frequency of 0.08 Hz and is able to detect changes in frequency of less than 1 Hz.

Abstract

In storing valuables such as electronics, money, jewelry, data and so on, it must be in a safe place. Because the safe factor is a social need of every human being. One of the triggers for crime such as theft, burglary or others is a lack of security, especially in the home environment. Another cause of security is that the door locking system still uses manual locks, making it less effective. Because the door is an important thing in a room, where we can always go in and out to store or put things. From these problems, a door guard using RFID (Radio Frequency Identification) or a fingerprint is needed to make the door safe from crime. This security system is designed using Arduino uno r3 ATmega 328 as a microcontroller equipped with an component of RFID reader and fingerprint sensor as well as a door lock solenoid to access the door. By scanning a fingerprint or scanning an RFID card, the data will then be processed and matched with data that has been registered or stored in the database to be able to access the door. Based on the results of the research that has been done, the value of fingerprint accuracy from 3 tests is 80,6%. The safety system can work quite well according to the design..

Abstract

Research and development on the implementation of renewable energy is growing rapidly, especially about photovoltaic (PV) and energy storage. Water pumped energy storage (WPES) is an alternative storage media in a standalone solar power system because of its longer technical life than chemical storage types, such as batteries. To assess the feasibility of WPES implementation as an energy storage in the standalone solar power plant system, the process of sizing the system components needs to be carried out by considering technical and economic aspects. This research will discuss the sizing process of standalone solar power system using WPES with closed loop reservoir systems and its economic analysis. The sizing process is carried out by the method of power balance, energy balance, and volume balance while economic viability is seen from the capital cost, O&M cost, and revenue from electrical energy absorbed by the load. In this study, the daily load profile with energy demand of 79 kWh and peak load of 4.36 kW. The analysis shows the need of 56 kWp PV system, 3800 m³reservoir capacity with 20m head. The calculation shows the technical efficiency of the system is 28.2%. From the economic analysis, the sistem’s payback period is 24 years, assuming the reservoir technical age is 50 years with net present value of Rp 2,072,823,731.86 and return of investment 105%.

Abstract

Internal Permanent Magnet brushless DC motor is one of the various types of electric motors using permanent magnets that are inserted into the rotor's core without having to stick it like a permanent magnet motor mounted on the surface.This motor has better torque characteristics, high efficiency, and sturdy construction. But the consequences in the use of permanent magnets can’t be separated from the interaction between the permanent magnetic field mounted by the rotor with stator teeth. So that development is needed to obtain the results of better cogging torque and efficiency, such as variations in the external rotor IPM-V angular range of 80 °, 90 ° and 100 ° in 18 slots and 16 pole models which are simulated using the Infolytica Magnet application based on Finite Element Method (FEM), the data is processed using Microsoft Excel, so that the output will be a parameter in the Simulink MATLAB 2016a modeling to get the characteristics of the design motor. Variation testing on the motor is done at a speed of 2100 rpm. The results of the test show that the minimum cogging torque value in the angle model of the 90 ° magnetic range is 1.64 Nm with the highest efficiency of 80.6%. Smaller cogging torque values will reduce vibration or noise when the motor is spinning. The high value of efficiency indicates the losses that cause heating on the motor are smaller, so that the motor operating period becomes longer.

Abstract

PT. Pembangkitan Jawa Bali (PJB) Unit Bisnis Jasa Operasi dan Pemeliharaan (UBJOM) PLTU Tenayan has protection equipment that serves as a support for power generation activities. One of the main protections used on PLTU Tenayan is differential relay transformer (87T). This Differential relay serves to protect main transformers from interference and work quickly and selectively in breaking interruptions. In electrical systems PLTU Tenayan, the main transformer and transformer UAT have a vector group configuration, thus causing the current flowing on both sides of the transformer will be different, and the current perceived by CT on both sides of the transformer will be different, so that the relay operates without any interference. On 9 December 2018, there was a trip on the generator Unit 1 PLTU Tenayan, causing blackout. This incident was allegedly due to lightning strikes on the transmission side of 150 kV. In this research will be conducted analysis of differential relay transformer (87T) with the consideration of vector group on PLTU Tenayan 2x110 MW. Research method with simulation using ETAP software 12.6.0. The results of the analysis of the simulations and calculations in the value of Idiff 1.5 Ie and slope of 120%, this value will be used for the setting differential relay transformer. From the test results obtained that differential relay transformer only works when internal disruption only and does not operate when external interference. So differential relay transformer (87T) safe from fault trip and operation fault.
