This paper presents a communication-aided distance protection and fault location algorithm for EHV series-compensated transmission lines based on Phasor Measurement Unit (PMU) and Synchrophasor Measurement techniques. The proposed algorithm utilizes the PMU to develop a distance protection and fault location scheme using synchronized voltage and current measurements from both local and remote end substations. The synchronized voltage and current measurements from local end are transmitted to remote end and vice-versa. Then, the determination of the fault zone and fault location is performed in both local and remote end distance relays without exchanging of any other signals (permissive, blocking, direct transfer tripping... etc.). In the proposed algorithm, both voltage and current signals will be communicated via PMU. This will offer great advantages of reducing the required digital communication channels and ability for reducing communication time delay errors. Moreover, in case of losing of the voltage transformer signal in the remote end substation, or if there is no voltage transformer, as in some old existing substations, the scheme is capable of calculating the missing voltage signal and maintaining a higher system reliability.","PeriodicalId":395633,"journal":{"name":"2014 Saudi Arabia Smart Grid Conference (SASG)","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122986656","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}

Now, with the introduction of embedded renewable generation and with the wide spread of Information and Communications Technologies (ICT), Transmission System Operators (TSO) are facing additional challenges during reconstruction due to uncontrolled generation, decrease of substation autonomy and increase of needed coordination with other actors (DSO, generation,...). In order to face these challenges, several strategies need to be developed by TSOs to speed up and increase the robustness of the system reconstruction: choice of frequency and voltage of reconstruction, determination of number of generating units regulating a network island and clearing or not of DSO substations prior to energization are strategies considered in this paper. In addition, different stages of system reconstruction are defined based on the capability of the reconstructed system to withstand unexpected events and faster reconstruction actions. This analysis leads to the elaboration of strategies and guiding criteria for the optimal design of a grid restoration process.","PeriodicalId":395633,"journal":{"name":"2014 Saudi Arabia Smart Grid Conference (SASG)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114662475","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 IEC 61850 standards suite is the most promising collection of standards for the design of substation communication and automation systems and has become accepted by utilities. Up to now there were no metering devices for billing according to IEC 61850 available on the market. Sampled values according to IEC 61850-9-2 can be used as input for high precisions metering. The meter as “cash-generator” in substations stores and transfers the billing values to the data acquisition system to support the billing process. The established standards for meters and data acquisition are DLMS/COSM. Further, DLMS/COSEM and IEC 61850 are based on similar structures with object models. To prove the suitability of this new metering solution based on sampled values installations are placed in substations in parallel to conventional metering solutions. Leading substation suppliers presented at CIGRE 2012 a new generation of substations with sampled values for voltage and current instead of conventional instrument transformers. Since 2012 several substations using sampled values as input for all devices were introduced worldwide. The results from thus installations are very encouraging.","PeriodicalId":395633,"journal":{"name":"2014 Saudi Arabia Smart Grid Conference (SASG)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134060664","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}
