Grounding their metal supports is, generally, considered an effective means of protection of the structure against the effects of lightning strokes, eventually \"attracted\" by the antennae themselves. The antenna's mast and the down conductor are incorrectly assumed capable of safely draining to ground the lightning current flowing at the point of strike. This, supposedly, would prevent both hazard for people and damage to the building and electrical equipment situated inside of it This paper will substantiate how the sole grounding of the antenna's mast can instead result in lowering the safety of the edifice, and, thereby, expose users to the hazard of dangerous electrical sparking (flashover) and possible fires.","PeriodicalId":285052,"journal":{"name":"2007 IEEE/IAS Industrial & Commercial Power Systems Technical Conference","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125253194","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 design has to be comprehensive and adaptable during the overall operational life cycle of the system, looking for the best methodologies and the most complete information. Safety configurations and accurate plans allow a guaranteed risk reduction so that in contingencies a competent operator can operate the power system properly. The authors suggest transitions maps for assisting the elaboration of the procedures from a set of a power system to another one and for helping the training of operators. In human reasoning and multi-modal information processing, the diagrams offer a visual clarity in examining spatial constraints and in recognizing correct inferences. The transitions maps extend the Euler-Venn diagrams and concur to an explanation of the four-color theorem.","PeriodicalId":285052,"journal":{"name":"2007 IEEE/IAS Industrial & Commercial Power Systems Technical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129099587","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 fact, an interval of self-extinguishing arc fault is marked in the plane of the elliptical orbits as edge between continuous and pulsating prospected behavior. The arc ignition introduces generally an asymmetry for the first half cycle of the invariant time evolutions. The arc current model is obtained as an extension of bolted short-circuit analysis: in a simplified approach the waveform of the arc voltage is limited to the fundamental harmonic. The simplified method, applicable with a system voltage either under 1000 V or higher 1000 V, allows to determine easily basic parameters, such as arc current RMS and peak values, conduction angle, arc power and arc energy.","PeriodicalId":285052,"journal":{"name":"2007 IEEE/IAS Industrial & Commercial Power Systems Technical Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130714706","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}

Solar panels characteristics depend on environmental conditions (insolation level, temperature and etc.). In this paper, design and simulation of fuzzy-based MPPT for the body mounted solar panel in a LEO satellite are presented. To show how good the proposed technique is; we applied it into a real system. Simulation results show that the proposed fuzzy-based MPPT ensures a more generated power so that the size of solar panel can be decreased. We used Matlab-Simulink environment for the purpose of simulation. It is shown that if we use the proposed fuzzy-based MPPT, the size of solar panel can be remarkably reduced leading to reduction of the weight and cost of power subsystem in small LEO satellites.","PeriodicalId":285052,"journal":{"name":"2007 IEEE/IAS Industrial & Commercial Power Systems Technical Conference","volume":"152 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131157698","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 critical loads sensitive to voltage sags in the plant have been identified from actual system fault contingencies. The power quality of these loads is enhanced by quickly islanding the subsystem with cogeneration units before tripping of the tie line with external Taipower system. According to the transient stability analysis of the rest of the industrial power system nearby Taipower network, the critical loads non-sensitive to voltage sags are isolated from external system faults in time to restore the system stability with the execution of proper load shedding. To ensure the normal operation of critical voltage sensitive load by considering the voltage tolerance curves, the proper relay settings for tie line tripping of the internal subsystem has been determined. In this way, the critical loads and cogeneration units in the industrial power systems can be survived from system faults to mitigate the production loss of industrial customers.","PeriodicalId":285052,"journal":{"name":"2007 IEEE/IAS Industrial & Commercial Power Systems Technical Conference","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126240446","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}

Five different interface algorithms are described and their respective characteristics with respect to the system stability are compared.

The methodology is implemented by utilizing specialized tools for calculating substation reliability, estimating economical efficiency and ranking substation alternatives. Depending of the industrial customer's preferences, different substation configurations, based on different technologies, can be modeled and analyzed. At the end, the proposed substation alternatives can be subjectively ranked by the customer using a ranking tool. A systematic procedure utilizing multi-objective value hierarchy is applied to make the final decision. A combination of \"hard\" attributes (usually presented in dollars) and \"soft\" attributes (subjective and difficult to express in numbers) are used for this purpose. The proposed methodology is applied for typical industrial substations. The results show the impact of combined criteria like the life cycle cost together with the customer's preferences on selecting reliable and economically efficient industrial substations.
