Cascade application of SPDs located at the service entrance of a building and near sensitive equipment is intended to ensure optimal energy distribution among installed SPDs, as well as proper equipment protection against surges. In the paper, scenarios of surges that are impinging at the service entrance of the building of interest and application of two-stage cascade protection have been analyzed. The influence of different cables lengths: arrester - suppressor (A-S) and suppressor - load (S-L), as well as influence of type and parameters of load on SPDs protection characteristics have been analyzed and discussed. Simulation programs ATP/EMTP and MATLAB are being used for analysis of several load types, namely resistive, inductive, capacitive, resistive - inductive and resistive -capacitive load, with the parameters of real devices which can be found in low-voltage AC power circuits. Performed analysis should to point on characteristics of loads and connecting cables which provide regular protection.","PeriodicalId":287461,"journal":{"name":"2008 43rd International Universities Power Engineering Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132420115","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}

A number of case studies are presented with respect to currently operational micro-, midi- and macro wind turbines within England and Scotland. Presently, the micro-, midi- and macro wind turbines have been categorised as those that have their nominal output within 0-2 kW, 2-20 kW and Gt20 kW power bands. Their electrical energy generation data have been critically analysed. In particular the turbinespsila capacity factor, the annual energy output and payback period are presented. It has been found that within urban settings micro-turbines perform poorly and hence they are uneconomical. The payback period for midi-turbines located at rural, high-altitude locations with clear horizons are of much shorter order. However, the sitting of such turbines is critical. For large public sector organisations, such as universities and institutions of higher education with a high electrical energy demand and base load, large, megawatt machines provide a sustainable and economic solution. It has been shown that for one Scottish university, presently under discussion, two 1.25 MW wind turbines provide the economical option with a payback period of 7.4 years. The capacity factor for the latter machine, to be located 35 km west of university campus will be around 0.14. The machine will be able to offset 84% of the total electrical load for Napier Universitypsilas Merchiston campus.","PeriodicalId":287461,"journal":{"name":"2008 43rd International Universities Power Engineering Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134152487","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}

It deals with the management of commercial, operational and administrative functions pertaining to estimating coal requirements, selection of coal suppliers, coal quality check, transportation and coal handling, payment for coal received, consumption and calculation of coal efficiency. The results are then used for cost benefit analysis to suggest further plant improvement. At various levels, management information reports need to be extracted to communicate the required information across various levels of management. The core processes of coal management involve a huge amount of paper work and manual labour, which makes it tedious, time-consuming and prone to human errors. Moreover, the time taken at each stage as well as the transparency of the relevant information has a direct bearing on the economics and efficient operation of the power plant. Both system performance and information transparency can be enhanced by the introduction of Information Technology in managing this area. This paper reports on the design & development of Coal Management Module (CMM) Software, which aims at systematic functioning of the Core Business Processes of Coal Management of a typical coal-fired power plant.","PeriodicalId":287461,"journal":{"name":"2008 43rd International Universities Power Engineering Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133906941","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}
