Meanwhile, the protection system has to be accurate in isolating the disturbance. Critical Clearing Time (CCT) became the main issues to determine the stability of the system after a disturbance happened. Critical Trajectory is a method to obtain CCT which is accurate and has faster calculation than other methods. In addition, Super Capacitor Energy Storage (SCES) is one of the reliable energy storages to store and supply massive electric power simultaneously. It is suitable with the nonlinearity pattern of transient stability. In order to improve the value of CCT, SCES is installed in the system. This proposed method is tested using IEEE 3-machine 9-bus system. The simulation result shows that the proposed method gives higher value of CCT in average range 0.0143s. It means the operation time of protection system is longer and it also has a longer time when a failure in protection system occur. As a result, the system will remain stable after a disturbance happen and it can improve transient stability of the system.","PeriodicalId":388463,"journal":{"name":"2018 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116964231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laryngeal retraction is done by laryngeal surgery. After the surgery, the laryngeal patients will lose the vocal cords and thus lose the ability to produce permanent sound. For post-laryngectomy patients, sound rehabilitation is necessary to able to conduct communication in other ways. There are 3 (three) ways of sound rehabilitation, namely esophageal speech, tracheoesophageal and electrolarynx. Sound has two kinds of intonation, namely high and low intonation that are used to emphasize certain words within sentences. Intonation also consists of three types of intonation, namely: dynamic pressure (low strong), tone pressure (high), and tempo pressure. The result will be used as the parameter to determine the start and the end of the sound. Electrolarynx is one of the tools used by the patient to talk in post-laryngectomy. In the previous research, electrolarynx prototype development is still needed to be improved, so that the optimal results to help human to be able to speak could be achieved. This research will describe the design of intonation control in electrolarynx using electromyograph sensor to raise human voice intonation in larynx (no larynx) and mute (deaf or speech impaired) in order not to sound monotone.","PeriodicalId":388463,"journal":{"name":"2018 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128224725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To design a controller, the designer needs some motor parameters that may not be provided by the manufacturer. This paper presented a design of performance and parameter measurement system for BLDC in electric scooter application. The investigated parameters were stator resistance, stator inductance, battery current, Back Electromotive Force (BEMF) constant, speed, torque constant, inertia moment, and friction. To obtain these parameters, a microcontroller was used to process some output signals from voltage, speed, current, resistance, and inductance sensor. Resistance and inductance were tested before the motor was operated. The motor was then given a unit step. During 5 seconds of motor running, the microcontroller recorded speed and current data. After that, the motor was unpowered. Later, the microcontroller recorded speed and back EMF voltage on each motor phase. The results revealed that the proposed system could measure the main motor parameters, such as 0.078 ohm of stator resistance, 76.52 µH of stator inductance, 20.28 volt/krpm of back EMF constant, 0.1936 Nm/A of torque constant, 0.0174 Nms of friction, and 0.0471 kgm2,","PeriodicalId":388463,"journal":{"name":"2018 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134216935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
