Different from traditional contactless methods whose sensors should be quite close to measured overhead lines, the proposed method uses a electric fled (EF) sensor located on the ground to measure the ground-level electric field distribution. Then, the remote contactless phasing test method can be realized based on the distribution waveform. The proposed method has been validated by experimental tests on a reduced scale model of double overhead transmission lines.","PeriodicalId":356367,"journal":{"name":"2018 3rd International Conference on Intelligent Green Building and Smart Grid (IGBSG)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126804225","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 authors test whether these devices may be used to ascertain the number of people in a building. The number of mobile devices present (number of persons) is determined using methods that capture network packets sent by mobile devices using the 802.11 protocol. The packets are captured using a Wi-Fi scanner, a hardware device that allows information to be gathered from 802.11/a/b/g/n/ac networks. The number of people in a building with an adequate count of Wi-Fi scanners may be determined with a definite probability which, aside from its statistical importance, might also be key in emergency situations in which it is imperative to determine how many people are inside a particular building.","PeriodicalId":356367,"journal":{"name":"2018 3rd International Conference on Intelligent Green Building and Smart Grid (IGBSG)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122557287","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 D2D communication, user is allowed to communicate with other user directly via D2D link controlled by BS. However, it is known that indoor environment cause multipath, which can be more severe for communicating devices that are located in a rack together with other objects. Therefore, the channel measurement of indoor D2D communication for devices in a rack is important to do. The measurement in this paper covers NLOS propagation with 3 pairs of transmitter and receiver locations in rack environment. Finally, baseband complex channel impulse response and average power delay profile of device-to-device communication are observed. From the result, the statistic of the measured multipath delay spread was observed that the value of mean excess delay were below 20 ns. It was also found that the longer the distance (i.e., difference of levels in the rack between transmitter and receiver) the higher the delay spread.","PeriodicalId":356367,"journal":{"name":"2018 3rd International Conference on Intelligent Green Building and Smart Grid (IGBSG)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124734912","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 new control scheme and operation principle is analyzed deeply, and then efficiency optimization can be carried out by the proposed design procedure for the resonant tank of LLC converter. Finally, a prototype is developed with input voltage range from 22V to 45V, and rated power of 250W and output voltage of 380V.

Therefore, human becomes immensely dependent with electricity. However, many of us do not aware with the use of electricity. Hence, a lot of energy are just wasted away and thus we are potentially subjected to an expensive electricity bill. In this paper, we propose a mobile application which is able to be run on Android based smartphone. The app is designed to have a high security by implementing a double encryption method, using both RSA and AES algorithm, to encrypt the communication data.

Firstly, the fluctuation components of wind power are extracted by wavelet decomposition to build a model involved bandwidth optimization, which is based on nonparametric kernel density estimation. Then a bandwidth optimization model is built constrained by goodness of fit test. Finally, constrained ordinal optimization is adopted to solve the model. Simulation results show that the model constructed by nonparametric kernel density estimation is determined by sample data without a prior probability density distribution, therefore this modelling method features with higher accuracy and more general applicability.

Smart Grid objectives include the integration of intermittent renewable energy sources into the electricity supply chain, securing reliable electricity delivery, and using the existing electrical infrastructure more efficiently. Unfortunately, current power grid infrastructure sometimes cannot provide high quality transmission channel due to channel interference, node distance or delay caused by included repeaters. This is the reason why network bottlenecks can appear in specific parts of the communication chain. This situation can then prevent data from reaching the destination nodes or delay significantly its arrival. In this paper, authors propose simulation scenario where the network congestion in case of network bottleneck is observed. First, the attention is focused on the available simulation tools most commonly used in similar Smart Grid scenarios. Then simulation of the behaviour of data transmission with different throughput values of bottleneck channels is provided. Obtained transmission time and calculated throughput in created network topology are evaluated with respect to requirements to PLC communication within the Smart Grid.","PeriodicalId":356367,"journal":{"name":"2018 3rd International Conference on Intelligent Green Building and Smart Grid (IGBSG)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121919422","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}
