The accelerated thermal aging of commercial transformer oil was conducted by increasing its temperature with different time. They were 100°C for 168 hours, 115°C for 96 hours, and 125°C for 48 hours. The lifetime of the tested oil was then estimated based on Arrhenius law and breakdown voltage test. The result showed that the physical characteristic of the tested oil during accelerated thermal aging could be analyzed based on its color changes, in which the higher level of thermal aging resulted in darker oil's color. The electrical characteristic was associated with significant decreasing of breakdown voltage. The lifetime estimation based on Arrhenius law for the tested oil with 100°C, 115°C, and 125°C were about 25663 hours, 4300 hours, and 1408 hours, respectively.

It is very potential for application the renewable energy. Based on the measurement, the maximum potential irradiance solar farm in the Island is accounted 610 W/m2. To convert the irradiance power to electricity, photovoltaic is applied. However, photovoltaic modules are drastically decrease their power output in case of the partial shading conditions. Therefore, perturb and obverse method (PnO) is introduced to track the point to establish the maximum power. In addition, the maximum power point tracking (MPPT) is employed to reduce the shading effects, thus by both method, the power generated is maximum. Besides, this technique is able to overcome the limitations in tracking efficiency, oscillation in steady state, and transient period. In this paper to maximize the irradiance observation, optimal site selection is undertaken by considering the tilt angles of PV and by approaching a sun path diagram model. Based on this study and experiment that have been taken in Giligenting Island, it is summed up that the proposed MPPT algorithm is superior to P&O technique with varies partial shading conditions. The results of the simulation yield that the power output of photovoltaic cover 99.4% of the load demand in Giligenting Island.","PeriodicalId":308504,"journal":{"name":"2017 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123430811","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 Decision creates a legal framework for solar energy market and promotes solar electricity development in Vietnam. Since 2016, Energy Department of the University of Science and Technology of Hanoi has been implementing a 15 kWp grid-connected photovoltaic (PV) system in Hanoi. The PV array performance is mostly influenced by its tilt angle, orientation, climatic conditions and geographic location. From simulated results, this paper aims to evaluate the performance comparison between a PV automatic tracking system and a PV fixed mounting system on identical PV arrays with the same rated powers in a one-year period, under similar environmental conditions and installed location. Firstly, the architectural design of the entire system is going to be described. Next, the energy outputs of the fixed and tracking system are analyzed by using the PVsyst software as a simulation tool [1]. This work examines the maximum performance of the PV output during the early stage of the system design by adjusting the optimum titled angle of the PV modules monthly, seasonal and yearly for non-tracking PV arrays. Then, the results are compared with the performance of automatic tracking systems. The study confirmed that the automatic single North-South axis tracker, which continuously tracks the sun from East to West, is the most suitable for PV system at Hoa Lac Hi-tech Park in the north of Vietnam, in the tropical zone.","PeriodicalId":308504,"journal":{"name":"2017 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130667496","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 symptoms in the infected rice plant are sometimes difficult to identify because they often shows the similar signs or characteristics so that only the experts who can identity them correctly. The infected rice plant actually can be identified since the beginning stage of planting until harvest time. So by knowing the symptoms in the early stage of the rice plant growth some preventif actions then can be done. Identifying pests and diseases of rice plant needs skills, experiences, and knowledge and should be done fast and accurate because the pests and diseases of rice plant can spread quickly and attack at all area of agriculture land. Since the number of experts in the pests and diseases of rice plant is limited, especially in a remote area, expert system then can be a smart solution for replacing the extensionist to decide what kind of pests or diseases that have attacked the rice plant. This paper presents a design and implementation of an expert system based on web application for diagnozing pests and diseases of the rice plant so that support system then still can be performed to provide the farmers with a correct decision. The knowledge representation model in this study used production rule and forward chaining based on symptoms or characteristics from attacked rice plant. The certainty factors method was used to define the expert confidence level for each symptom. This expert system testing was done by 15 person of non-extensionist of agriculture and 20 person of agriculture extensionist for observing 12 sample of images of the infected rice plant. The testing result showed that the accuracy level of this system is 73,81%. Meaning that this expert system can help farmers determining the pests or diseases of rice plant.","PeriodicalId":308504,"journal":{"name":"2017 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"501 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114746277","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}

In addition to the non-linearity, each state on the QTP dynamics is coupled, and the level sensor is only installed on two tanks to be set, this adds to its complex QTP control issues. By performing the linearity using Nonlinear State Feedback Decoupling (NSFD) method, we can establish a closed loop system that is linear and meets specific response specifications in accordance with the desired design specifications. Since NSFD requires measurements of all states, it is necessary to add a Non-Linear State Observer (NLSO) so that the other two states can be observed from two measured states. By specifying time response design in the form of time constants T1 = 4 seconds, and T2 = 4 seconds for tank one and tank two respectively, and installing a 1st order low pass filter with time constants t = 0.2 second for Cross Coupled Error Feedback (CCEF) on NLSO, then we can obtain a simulation result that meets the specification of the desired transient response.","PeriodicalId":308504,"journal":{"name":"2017 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128259214","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}
