Comprehensive Evaluation of Reliability of Protection System in Smart Substation
The reliability of smart substations has a great significance on the safety and stability of smart grid operation. Taking the protection system in smart substation as an example, this paper constructs comprehensive reliability models to evaluate the reliability of smart substations with different architectures. The paper first illustrates two important aspects which affect the reliability of th...
متن کاملSmart Local Backup Protection for Smart Substation
Received Apr 11, 2017 Revised Apr 28, 2017 Accepted Jun 17, 2017 This paper presents a novel smart local backup protection SLBP used for the support and backup of the protective relays in a smart substation. The proposed SLBP is based on the IEC61850 standards and the concept consists of the acquisition of Generic Object Oriented Substation Event GOOSE used for tripping and interlocks exchange ...
متن کاملResearch on Source Maintenance Key Technology of the Smart Substation
The source maintenance technology of the smart substation offers the base for the models, data and graphs sharing between the substation and the dispatch center. This paper researches on the conversion technology between SCD model in IEC 61850 Ed. 2 and the CIM model in IEC 61970. The substation provides SVG and SCD documents to the dispatch center, which includes primary equipment information ...
متن کاملWireless Protective Relaying Scheme for Smart Grid Protection
Integration of Distributed Energy Sources (DESs) with traditional grid besides having many technical advantages, poses technical challenges to power engineers. Bidirectional power flow, dynamic fault currents are the few challenges. The relay settings need to be made adaptive to dynamic fault current levels of power system with DESs. Intelligent Electronic Devices (IEDs) can effectively be depl...
