Fault current limiters (FCLs) are new and attractive devices to reduce short-circuit current levels significantly without adding additional impedance during normal operation. This paper summarizes the present R&D status of new FCL technologies, in particular superconducting FCLs (SCFCLs). At present SCFCLs are not commercially available but first field tests of medium voltage demonstrators showed the technical feasibility. In general, different types of SCFCLs have been developed and it depends very much on the specific application which type fits best the requirements. For the future, the two major R&D objectives are to develop high voltage SCFCLs (>100 kV) and simple and low cost SCFCLs for medium voltage levels (6-36 kV)","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125772124","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 paper highlights some key (not all) activities of the IEEE standard 762 working group over the last three years. It also highlights how the North American Electric Reliability Council's (NERC) generating availability data system (GADS), a big supporter and user of IEEE 762, uses these new modifications in its reports and training of data reporters.

Opponents tend to be highly skeptical of claims made by environmental groups that energy from renewable sources can be produced cost effectively.

For both of them are complicated combinatorial algorithms, it is hard to effectively combine these two important means to do better optimization. In this paper, a joint optimization algorithm, based on the combination of capacitor switching and network reconfiguration, for loss reduction in distribution system is proposed. In method, an improved adaptive genetic algorithm(IAGA) is developed to optimize capacitor switching and is taken as the main optimization flow. The formulation of network reconfiguration is simplified according to the parameter features after capacitor switching. Capacitors at each location are encoded into binary strings and comprehensive optimization results, after carrying out network reconfiguration for each encoding string, are evaluated as fitness values of encoding strings. For IAGA based main optimization flow and the simplified formulation of network reconfiguration, the proposed method has effectively solved the problems of low computation efficiency and small searching spaces of the conventional joint optimization method.

In this paper, a new mechanical damper scheme based on participation factor approach is proposed to damp torsional torque and prolong the life of turbine mechanism. Two types of torsional damping couplings, inertia damping coupling and elastic damping coupling, are adopted and examined. The optimal type and the optimal location of the damping coupling will be identified and installed to the turbine generator shaft section.
