Smart meters of SG allow the transfer of the measured signals in the wind farm to the operation and protection centre of the SG. Such signals transmission can improve the farm performance and reduce system cost. The secure operation of wind farms requires an efficient over speed protection of the turbines under wind gust conditions. Therefore, this paper is concerned with integration of a new over speed protection algorithm with the existing protection centre in SG. The main objective of the proposed algorithm is the dynamic updating of Critical Clearing Time (CCT) for over speed protective relays against severe wind gusts to minimize loss of life and component damage. In this respect, long-term data of wind speed of Zafarana farm have been collected and processed to define gust intensity and its distribution Moreover, the geographical farm area is classified to different rows according to the recorded gust values. A smart relay setting will be formulated by developing heuristic algorithm, which relates CCT with the gust intensity, and its row along the geographical area of Zafarana farm. Accordingly, general two variables second order function will propose to identify the dynamic CCT based on wind speed measured by smart meters installed on each wind farm row. The digital relay settings are updated according to the determined CCT using the communication facilities existing in the SG. The simulation results indicate that the proposed over speed protection improves significantly the performance of the grid connected wind farm under wind gust conditions.","PeriodicalId":44634,"journal":{"name":"SAE International Journal of Passenger Cars-Electronic and Electrical Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87072050","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}

Although frequency monitoring ensures system stability and calls for the Under Frequency Load Shedding scheme, other conditions that threaten power system stability like the loss of a tie line, overload trip of a power transformer, and overload trip of a transmission line need to be automated as well. This will not only improve reliability and continuity of service but also fast decision making, reduce the blackout zone, unnecessary load shedding, and minimal downtime. This paper presents a load management scheme that performs automatic load monitoring and feeder restoration by strictly following the set threshold values using PCM600, an ABB tool. The 11KV feeder load shedding hierarchy was strictly selected according to utility income-priority, strategic supply and safety. The logic configuration from PCM600 was validated and the Generic Object Oriented Substation Events (GOOSE) report was published. The Configured IED Description (CID) file from each IED (in PCM600) was saved in Substation Configuration Language (SCL) format and imported into IEDScout to simulate the IEC61850 communication. The simulation using IEDScout achieved a 500ms GOOSE messaging sequence and the traffic on the Ethernet cable was captured and analyzed using WireShark, a graphic user interface network protocol. A cost benefit ratio of 1.647 (greater than 1) was obtained to declared economically acceptable. This design caters for emergencies, i.e. very rare, non-continuous but possible and very catastrophic occurrences on the power system. Therefore this research provides an efficient solution to transmission line and transformer overload by automating downstream load-shedding and load restoration.","PeriodicalId":44634,"journal":{"name":"SAE International Journal of Passenger Cars-Electronic and Electrical Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2332-0796.1000283","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72542448","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}

Different techniques were used to characterize the SiC sample: the cylindrical resonant cavity technique in transmission and reflection mode, the microstrip ring resonator and finally the near field microwave microscopy. The results obtained by the cylindrical resonant cavity (transmissionand reflection) are in good agreement, the relative permittivity and the loss tangent of the SiC increase with temperature by 48% and 190% respectively between 25°C and 165°C. These techniques are accurate but need two thermal cycles. The results obtained by the microstrip ring resonator are less accurate than the resonant cavity and the low quality factor (Q0=2.5) does not allow to correctly determine the imaginary part of the permittivity and consequently, the loss tangent. Finally, the near field microwave microscopy technique shows an accurate measurement with low uncertainties in the real (<2%) and imaginary part (<5%) of the permittivity. These results are in good agreement with the resonant cavity techniques, however this technique needs just one thermal cycle which allows saving time during the measurements.","PeriodicalId":44634,"journal":{"name":"SAE International Journal of Passenger Cars-Electronic and Electrical Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80898022","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}

However, the non-isolated DC-DC converters would share a common ground between the input and the output terminals. The isolated DC-DC converters can be used as a positive grounding or negative grounding. Furthermore, isolated converters have found wide application recently due to their advantage over non-isolated converters. In addition, electrical isolation of input and output ground connections is for safety. The voltage and current stress on switches can be minimized using transformers. Moreover, the first winding can be used to put in energy into the inductor; as a result, the inductor that could gradually increase the energy from the inductor to the load cannot be available for the other coil. The two significant topologies of the isolated DC-DC converters are flyback converter and catch-winding forward converter. Therefore, the main goal is to analyze and investigate the impact of change in switching frequency, duty ratio, load and the input voltage for every topology and to find the critical points for every topology by comparing the results with every figure done through this work [1].","PeriodicalId":44634,"journal":{"name":"SAE International Journal of Passenger Cars-Electronic and Electrical Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90763684","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}
