The powerful analyzing and decomposing features of Wavelet Transform(WT) along with the accurate phasor extraction feature of Discrete Fourier Transform(DFT) has been combined to develop this useful and effective protection scheme. The whole idea of the proposed scheme is to extract third level decomposed current signals at each substation using Wavelet Transform. Then third level approximate coefficients(CA3) are reconstructed for each line current at every substation to derive operating and restraining quantities after extracting the respective fundamental phasors by using DFT. The proposed scheme has been tested on a 500 kV, teed-transmission line in the presence of UPFC and Wind Farm (as one of the substation) under various fault and operating conditions on MATLAB environment. The results given in section-V shows the feasibility of the proposed relaying scheme. To compare effectiveness of the proposed differential relaying scheme along with the conventional relaying scheme, different types of faults have been simulated at different location of the transmission line by considering three statistical metrics (i.e Dependability, Security and Yield) and result has been compared and shown in table-1.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129673989","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 for low power and real-time applications they are finally implemented on embedded systems with fixed-point arithmetic. Implementation of signal processing algorithm in fixed-point arithmetic involves a floating-point to fixed-point conversion process. Wordlength optimization plays a significant role in this conversion process, reducing area, power and latency while maintaining the accuracy constraint. Simulation and analytical approaches are two techniques used for optimizing the wordlengths. In simulation based approach a new fixed-point simulation is required to run for every modified wordlength. Bit true (fixed-point) simulations are not necessary to run for analytical based wordlength optimization methods. Therefore this approach requires the derivation of the cost model and the performance (signal to quantization noise ratio) as a function of wordlengths of different variables of the algorithm. Hence in this paper we have carried out a detailed study on the derivation of the cost model for fixed-point FFT algorithm. Cost models under various quantization modes are discussed and compared.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115299022","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}
