It shows the results of the algorithm that detects an outage and enables the digital processing to control the static switch. This algorithm was based on the Clarke and Park transforms. The operation of the switch consists of transferring the power supply from the main source, where an outage occurred, to an alternative power source (backup). The load stays off for a time of milliseconds. A low voltage prototype was built, to allow the evaluation of the algorithm. Then a prototype of the static switch was built in voltage of 13,8kV. The first tests - feeding resistive load - are presented in voltage of 13.8 kV.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123259312","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 model was simulated using the power system simulation tool in MatLab SIMULINK. The simulation of the system is implemented by using step change and linear change input to the wind turbine with an initial wind speed value of 4 m/s and to a final value of 15 m/s. In a step change, it is observed that the output load current increases quickly from 5.2 to 18.3 Amperes in just 0.12 second while in a linear change wind speed input, it is observed that the load output current linearly increases from 5 to 18 Amperes in 0.5 second. Its voltage output approximately remains constant at any change of wind speed. It is found out that there is a small time delay (around 0.2 second) in the response of the load current. The system current output has no unwarranted overshoot or spike even though there is a sudden increase of wind speed. This indicates that it has a stable output current even though a wind gust occurs. Hence, this shows that experimental observations validate the results of the simulation.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124389189","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}

Many kinesin nanomotors can attach to a single cargo and coordinate their behaviors to transport the cargo. This behavioral coordination of kinesin nanomotors can be defined through a communicational language that kinesin nanomotors follow to transport the cargo. This paper proposes a computational language for kinesin nanomotor which is inspired by the nanomotor's natural behavior. In this technique, we have used behavioral Deterministic Finite Automaton (DFA) model of kinesin nanomotor which indicated internal intelligent and autonomous decision-making process of the nanomotor in response to its cell. In addition, the behavioral responses of kinesin nanomotor to its cell, behavioral DFA model of the nanomotor, were mapped to a computational regular language for the nanomotor. The proposed computational language for kinesin nanomotor was acceptable by the behavioral DFA model and also in good agreement with the natural behavior of the nanomotor. The development of such computational languages among intelligent and autonomous nanoparticles in nature paves the way for constructing potential bio-inspired nanorobotic systems as well as designing of some computational languages for their controlling.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125332805","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 work focuses on wireless ad-hoc multisensor network based localization and threat estimation of such a buried gas source. It is reasonably considered that the gas source effuses methane (CH4) and volatile organic compounds (VOC) over a large indoor environment. Experiments are performed to emulate the subsurface gas diffusion process. The propagation constant of CH4 is also determined experimentally. First, the maximum likelihood (ML) method is used to estimate the most probable gas source location within a target area. It uses gas concentration readings sensed by the multisensor nodes at different predetermined points over the large area. The initial localization belief is next refined using a judiciously chosen subset of sensor nodes with limited mobility. Simulation results indicate that the proposed source localization algorithm offers higher estimation accuracy with reduced hardware using lesser energy resources. Finally, we propose an analysis that helps to estimate the explosion-threat possessed by the landfill source. Since VOC exposure has severe ill effects on human health, a VOC concentration measurement scheme is also proposed here.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122525046","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}
