For this reason the long distance transmission cables are of utmost necessity for effective power transfer, which in-evidently results in huge losses across the system. The Reliable electrical network is one that transports the energy with minimal power losses, losses corona effect represent one of causes that hinder reaching this performance in HV lines are either permanent mode or in the transient mode. In this paper we present the phenomenon of corona and its behavior in different climatic and atmospheric conditions such as rain, humidity, the dust, the sand, dry weather of the one part and over-voltages induced by strokes lightning.

New network management approaches and innovative equipment are needed to handle highly volatile voltage profiles resulting from intermittent distributed generation. This paper investigates the use of an inline voltage regulator in a LV network. As simulations based on realistic feed-in scenarios show, it is an efficient tool for influencing a network's voltage profile. Since voltage regulation is not required permanently, such a flexible power electronic device can be further used to increase a power system's efficiency and reliability by implementing features such as reactive power compensation or mitigation of harmonics. Concerning this matter, an approach for an adaptive system management is discussed that allows the provision of additional functionality whenever the converter is not used to its full capacity for the voltage regulation task.","PeriodicalId":325670,"journal":{"name":"2014 16th International Power Electronics and Motion Control Conference and Exposition","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125242570","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}

Control rooms are still the heart of operations, where several security guards spread their attention over an array of monitors, trying to find events. In some cases, a set of sensors may be used to help detect intrusion or fire, but these are seldom integrated with video surveillance. Under a research project (DVA) we developed a new approach to surveillance systems based in geographic position of events, sensors and security agents. This new architecture, based in geographic positions, is fully distributed (empowering sensors with processing skills), bridging them together in a society of software agents that, supported by inference capabilities, work for a common awareness and, given that they are location aware, can direct the appropriate security officers for each kind of emergency.","PeriodicalId":325670,"journal":{"name":"2014 16th International Power Electronics and Motion Control Conference and Exposition","volume":"30 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120907238","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 has been done because of the varying conditions so that the loss of power can be minimized. The main factor which decreases energy output of the photovoltaic PV solar systems is partial shadowing. The way the energy output of partially shadowed arrays varies with the system configuration used, has been studied extensively. A huge degree of disorder still exists, particularly with respect to the best modularity grade for these systems. There are two distinct sub-divisions in the systems implemented in the reconfiguration mechanism: reconfigurable solar arrays, and a switching matrix to do a reconfiguration. Using different methods, the proportions of shadowing obstructions were noted to allow for calculation of the likely shadowing losses. The outcomes of this paper on modeling and monitoring are used to evaluate the photovoltaic system with respect to shadowing losses with different levels and their reliance on the system configuration are selected. It has been found that power loss because of varying conditions is majorly due to the decrease in radiance occurring on the photovoltaic array and can be avoided through selecting the suitable configuration and connection. The simulation results show that the output characteristics of the simulator presented better results with that proposed model.","PeriodicalId":325670,"journal":{"name":"2014 16th International Power Electronics and Motion Control Conference and Exposition","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125946442","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 topologies are designed in such a way that they can provide both positive and negative compensation of the grid voltage.
