PD is one of the most important parameters of PT to ensures the reliability and quality of the PT's operation PT. As PT is one of the most important parts in electrical power system, PD becomes one of the key performance indicators for PT. The quality of manufacturing process of both liquid and solid insulations will reflect to the PD value of PT. Both solid and liquid insulation will form the overall insulation of integration of PT. One of the important manufacturing processes is vacuum and oil impregnation process. These processes ensure the removal of the moisture from PT insulation and keep maintaining PT from moisture ingress. In this study, the experiment is conducted to investigate the relation between vacuum and impregnation process duration to partial discharge value of 167 MVA 500/150 kV on single phase power transformer. Twelve (12) samples are investigated during manufacturing process and final acceptance testing by measuring vacuum and impregnation process duration as well as the value of partial discharge. The result shows that vacuum process duration has significant effect to PD values. Combined with oil impregnation process of the insulation, the results show that to achieve PD below 70pC (<70pC), the optimum vacuum duration is 57 hours and the oil impregnation duration is ranged 75-120 hours. This practical study is beneficial for both the owner and the manufacturer of PT, so it gives the optimum duration for manufacturing process to get lower partial discharge at optimum duration and cost.","PeriodicalId":427328,"journal":{"name":"2019 IEEE 2nd International Conference on Power and Energy Applications (ICPEA)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121488899","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 communication among electrical power substation is an essential part of the protection system in electrical power transmission for providing a reliable network. So far, the Indonesian electric utility entrusted the third parties to provide the communication network. However, this pathway has the drawback in data transmission, for instance data delayed, because it is not directly integrated with the system. Thus, in this study, we proposed a novel built-in method that allowed the user to conduct a real-time monitoring on the entire system. We implemented two stages; the first stage was to deploy the primary multiplexer to provide 2 Mbps loop network, while the second stage was to develop the independent network by installing the synchronous digital hierarchy (SDH) network to replace the existing one. Based on G.703 channel test, we found that the proposed network was capable of replacing the third parties network, confirmed by direct testing using network monitoring system.","PeriodicalId":427328,"journal":{"name":"2019 IEEE 2nd International Conference on Power and Energy Applications (ICPEA)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124578083","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}

However, the use of energy has witness tremendous challenge in recent years because of high cost of raw materials for generation (fossil fuels), environmental concerns and sustainability of resources. In recent years, the use of renewable energy resource takes a centered stage with wind energy as the front runner. This is largely due to its availability and maturity in technology. The biggest challenge for generating electricity from wind is its inherent property of speed intermittency; it also affects correct forecasting for future planning. Statistical approach using Markov modelling method is used to predict wind speed using dataset from a location collected over 24hrs period at an interval of 10mins. Results from this method shows it performs well during the early periods with Individual Absolute Error between 0.3-1.43 during the first five (5) periods of the forecast and for the last five periods the absolute error is from 1.3 to 3.0 making Markov probabilistic model good for very short term forecasting of wind speed.","PeriodicalId":427328,"journal":{"name":"2019 IEEE 2nd International Conference on Power and Energy Applications (ICPEA)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114218069","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}

Coated conductors are made from Yttrium-Barium ceramic powder where stabilizer and substrate are being coupled together to strengthen the tape architecture. Practically, AC losses are found to occur when current is flowing through the tape and the losses are high when large currents flowing through the coated conductors. In this work, a 2D numerical model has been developed where the effect of number of turns on the AC losses for magnet coils/stacks has been examined using SCS 12050 tape having 12mm width and critical temperature as 240 A. The numerical model is based on H-formulations integrated with E-J Power law where homogenized approach has been proposed to estimate the magnetic flux density and AC losses. The model is being tested for a sinusoidal input having 50 Hz frequency for the full cycle.","PeriodicalId":427328,"journal":{"name":"2019 IEEE 2nd International Conference on Power and Energy Applications (ICPEA)","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132435241","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}

This challenging goal is affected by several factors and roles which play important roles by which this goal is affected. Those factors in most cases are difficult to be treated by one method or design. Many proposed systems have been introduced for many years; their performance(s) have varied percentage(s) of achievement in terms of energy savings. In this setting, such a review paper could help much to draw a clear plan for researchers and buildings’ designers to follow and get them directed to best and easiest systems. However, many review papers have been published which included many limitations, e.g., some review papers focused only on residential buildings. In general, there is a need to give an overview of reviewed papers with taking into account many factors and policies together with strategies applied. In this setting, it is understood that different designs have produced different levels of performance being achieved. In this review paper, Building Energy Savings Strategies and Systems (BE3S) are reviewed. Different points of views have been considered. For example, lighting control systems, buildings’ retrofitting systems, and occupancy profiles related systems have been reviewed. This paper has also included different types of buildings on which strategies and systems have been applied. Reviewed papers are collected from top-tier journals published by very well-known publishers which are IEEE, Elsevier, Emerald, MDPI, and ACM. Indexing services adopted in this BE3S paper are Scopus and WOS. BE3S paper has only considered last 20 years providing a summary of recently designed strategies achieving semi-optimal performance(s) in terms of energy savings in buildings.","PeriodicalId":427328,"journal":{"name":"2019 IEEE 2nd International Conference on Power and Energy Applications (ICPEA)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115463679","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}
