- PublicationDesign of a multipurpose smart meter (moniter)(2016)Suhairulazan SamanThis thesis reports the design, development and analysis of a multipurpose smart meter (MONITER). The existing smart meter did enable the consumer to see the usage detail, however, the access is not quite easy. So, the project is to make the access easier, and at the same time, adding extra feature which is the usage for each appliance, and the data privacy. The project aims to solve this problem and can be applied in any common house unit. Therefore, in the project, a main data collector which collects usage data from selected appliance and store it in microSD card and is able to transmit the data via Wi-Fi Direct to smartphone is designed. In order to obtain the electrical usage, a measurement unit that measure usage for selected appliance and able to send the data to the main device via power-line communication is designed as well. With the Wi-Fi Direct from the main data collector, the electrical usage data can be accessed from any Wi-Fi-enabled device through any web browser by the user. The MONITER system will make the user able to identify which appliance consume more power, and which appliance consume less. Thus, the user can take appropriate step to lessen their electrical usage significantly.
- PublicationPower flow tracing methods and its implementation for power system-wide area network(2016)Muhammad Faiz BakarChanging a monopolistic structure of a power system by a single utility to a deregulation market will create issues largely regarding the transmission losses and efficiency. In order to grasp the operation of power system network from generation to transmission, a power flow tracing methods ranging from real power, apparent power and complex power are being studied and compared. Thus from the comparison study, a real power flow tracing technique incorporating upstream-looking algorithm are being performed in this paper A principle of proportional sharing from topological generation distribution factor are being applied. In addition, a load flow solution of MATPOWER package which is run in MATLAB is done initially comprising of IEEE bus system networks. Results from the tracing by hand-calculation and coding shows that real power fraction from particular generator can be known to supply the individual loads. From the result, monitoring and controlling of generation to transmission can be performed. It is recommended to perform cost analysis in transmission losses as well as efficiency of power producers' participants for future studies.
- PublicationAnalysis on the behavior of the grid system with distributed generation during abnormal condition(2016)Zahaer Firdaus ZaharudinThis thesis reports the study on the grid behavior with distributed generation (DG) during abnormal condition utilizing Siemens PSS/E software. Inverter based DG in particular photovoltaic plant is focused on. Previous study states that DG implementation may affect the system both positively and negatively at steady state. Similarly, it can have adverse effect during abnormal condition such as system fault. This study consists of the development of a stable test system as a platform for applying different case study. A test system is modelled based on IEEE 39-bus system to replicate a high voltage power system. Dynamic simulation is applied to study the effect of DG implementation to the high voltage transmission grid. Comparisons in terms of DG presence, size and fault location allow further analysis regarding its correlation with existing theoretical knowledge.
- PublicationDesign and development of an interactive humanoid robotic head with vision sensor, speech recognition and speaking abilities(2016)Ahmed Ali Omer AliHumanoid robots are nothing new and researchers are still conducting studies to develop humanoid robots. Humanoid robots are designed to resemble human body shape. So far researches show that there is no a fully-head features humanoid robot. Designing of the humanoid robot depends on the purpose of the design. Some forms may model only part of the body of the humanoid robot, if the design only focused on the lower part of the body the experimental purpose might be studying some related actions such as the study of bipedal locomotion. If the designed is constructing the upper body of the humanoid robot the main focus is to study the artificial intelligence of the robot. The project focuses on the study of the artificial intelligence of the humanoid robot by designing an interactive humanoid robotic head with some vision sensor working in the principle of image processing of video frames captured by a webcam. The robotic head is able to recognize people registered in the database which is containing a number of facial images. The robot has the ability to communicate and interact with these people in different ways. Even more, the robot is able to track some objects based on the color tracking algorithm. The color of the object is set manually, by programming and designing tracking bars. The robotic head is able the recognize speech as it can be controlled over the voice commands or it can answer some question. The speech recognition algorithm is simply a speech to text synthesizer that comes with a series of speech recognizers and acoustic models. The robot is trained to recognize certain words and phrases based on a dictionary file generated with these words and their phonetics. The robot can interact with people by speaking using a text to speech engine that generates sound files. As the robot speaks the spoken words are synchronized to the servo motor attached to the lower jaw. The robotic head is constructed with ten servo motors mounted in different positions to derive the head features. Nine of them are connect to the Raspberry Pi and only one servo motor is connected to a different board to perform the audio to mouth synchronization. The entire head structure is 3d printed and modeled in a 3d modeling software.
- PublicationSmart baby walker(2014)Zuikhwan ZulpitriA baby walker includes motor-driven wheels with the motor being connected to sensors on the walker and to a remote control system. The sensors on the walker prevent the walker from get nearer to unsafe area such as stairway and avoiding from falls down stairs. Safety wheels move the walker to the secure area. The sensor values given will be outside the specified range when no object present, and fall between a specific ranges when an object detected. The remote control system is used, so the adult can exert control over movement of the walker. Radio frequency controller is used since it is capable to transmit and receive the signal up to 100 meters range around the open area.
