Asari, Youguang Guo, Jianguo Zhu","doi":"10.1109/EnCon.2019.8861264","DOIUrl":"https://doi.org/10.1109/EnCon.2019.8861264","url":null,"abstract":"In high magnetization frequency of the high speed electrical machine, core loss dissipation is a main contributor of the power loss that gives high percentage of loss compared to the other losses. Previously, the engineers has considered SOMALOY 500 as a core of electrical machine but they still aim for the lower loss magnetic material that can offer higher efficiency during the operation of the electrical machines.. There is no standardization for rotational core loss of magnetic material that needs more effort in order to predict the core loss accurately. In this paper, core loss of SOMALOY 700 (5P) is calculated and analyzed to identify the magnetic properties of that material. The magnetic properties of SOMALOY 700 (5P) material are properly measured under alternating magnetic fluxes at 50 Hz, 100 Hz, 500 Hz and 1000 Hz by using 3-D tester. The material characteristics under alternating fluxes are important to estimate the total rotational core loss in the future. LabVIEW and Mathcad software are used for the data acquisition and analysis, respectively. The performances of SOMALOY 700 (5P) are compared to SOMALOY 500 by plotting the core loss curves and hysteresis loops. The finding shows the core loss of both samples is proportional to the squared of magnetic flux density. This study also revealed that the core loss of SOMALOY 700 (5P) and SOMALOY 500 are 6 kg/Watt and 12 kg/Watt when the magnetic field is at 1.5 T. It concludes that the SOMALOY 700 (5P) offers lower core loss compared to the SOMALOY 500 and more suitable to be used in producing high performance of electrical machines. The details of core losses for both SOMALOY materials are important in order to provide the significance information to the real engineers in designing the electrical or electromagnetic machines in the future.","PeriodicalId":111479,"journal":{"name":"2019 International UNIMAS STEM 12th Engineering Conference (EnCon)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128355376","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}

Therefore, silt flowing with water passing through the turbine is the root cause of silt erosion of turbine components. While passing through the generating units, suspended silt in water is subjected to the force of gravity, viscosity, inertia, turbulence and cavitation. Combination of these forces makes silt movement highly complex under varying velocity profiles and pressure gradient. Estimating the operational impact of suspended sediment on the run-of-river small hydro power plants is inherently depends on the long-term background or baseline sampling of the sediment in intake streams. The purpose of this study is to investigate the suspended sediment distribution profile of run-of-river small hydro power plants. Major undertakings were carried out on particle size distribution (PSD) and suspended sediment concentration (SSC) for estimating the operational impact of suspended sediment on the run-of-river small hydro power plants. The study encompassed programs for suspended sediment and streamflow profiling at different river geological profiles as well as their potential impact on the operation of small hydro power plants.","PeriodicalId":111479,"journal":{"name":"2019 International UNIMAS STEM 12th Engineering Conference (EnCon)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131981148","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}

Renewable energy resources can be seen as an alternative energy to capture the remote rural electrification’s problems. Installing and operating a renewable energy generation is not difficult but it requires cautious step as to make sure maximum use of energy can improve the electrification. Therefore, the aim of this paper is to critically analyze five types of optimized hybrid renewable energy systems in term of financial and power production using HOMER software. This paper approaches four renewable energy resources, namely solar, hydro, wind and biomass in three remote rural areas located in Limbang, Kapit and Sri Aman regions. Different combination of solar PV system, micro-hydro generator, wind turbine and biomass generator together with battery storage and converter were studied. The optimization between these different sizes of system was built based on energy demand satisfaction, system cost and carbon gas emission. Comparison between operational of behaviors hybrid renewable energy systems with stand-alone diesel generator only were also carried out to elucidate the effects on investment cost and environment. The results revealed that hybrid hydro with battery system is seen to be the cheapest system and has the best technical performance in all locations. Solar PV and biomass generator system were combined with hydro generator as a backup power. It is also found that hybrid renewable energy is more cost-effective and reduce of carbon emission compared to standalone diesel generator.","PeriodicalId":111479,"journal":{"name":"2019 International UNIMAS STEM 12th Engineering Conference (EnCon)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129068321","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}

The impacts of this activity are devastating to the environmental and human health. To prevent illegal waste dumping, sufficient waste treatment facilities, for instance roll-on/roll-off (RoRo) waste containers must be placed strategically for community use. However, the result would not be significant without an efficient waste monitoring system. Hence, an integration of IoT-based sensors and mobile apps are proposed with the objectives of providing real-time information of waste fill level, RoRo waste container geolocation and waste decomposition level to users by uploading the sensor data wirelessly to a globally accessible domain. An Arduino UNO is chosen as the microcontroller for the application. Multiple HC-SR04 ultrasonic sensors are used to measure the waste pile level at different point in the RoRo waste container, hence the fill level; NEO-6M GPS module is used to measure GPS location; MQ-3 ethanol gas sensor is used to measure ethanol gas concentration, hence the decomposition level; ESP8266 ESP-01 Wi-Fi module is used for wireless transmission of sensor data to a website. Windows 10 and Android applications are developed successfully as a platform to display the real-time information of the RoRo bins. To sum up, this research is a good approach against the illegal dumping issue as it provides the users an alternative way to dispose bulky wastes legally and conveniently.","PeriodicalId":111479,"journal":{"name":"2019 International UNIMAS STEM 12th Engineering Conference (EnCon)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126357051","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}
