The hourly wind speeds are forecast utilizing a time series method. Both the energy credit and capacity contribution of a wind energy conversion system can be quantitatively assessed using the proposed model. The IEEE Reliability Test System is used to illustrate the simulation procedure.<<ETX>>","PeriodicalId":146674,"journal":{"name":"IEEE WESCANEX 93 Communications, Computers and Power in the Modern Environment - Conference Proceedings","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127186819","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}

By dynamics is meant the response of the relay to a current of varying magnitude. The test method, originated by IREQ, is used by Hydro Quebec to determine the ability of new relays to coordinate with the installed base of induction relays. Concurrent with this work, working group G7 of the Power System Relay Committee for the IEEE Power Engineering Society is completing a standard for inverse time-overcurrent characteristics which define equations for microprocessor relays based on the physics of induction relays. The authors discuss the correlation between the dynamic tests of induction relays and the proposed standard equations for reset and trip characteristics of microprocessor-based relays.<<ETX>>","PeriodicalId":146674,"journal":{"name":"IEEE WESCANEX 93 Communications, Computers and Power in the Modern Environment - Conference Proceedings","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124109140","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}

One of these uses a decision directed version of Gardner's algorithm, and the other uses a recently introduced technique called sample-correlate-choose-smallest (SCCS). For the first method, the authors find exact solutions for the root-mean-square (RMS) phase jitter, mean time to acquire synchronization, and mean time to symbol slip in the case of binary nonreturn-to-zero (NRZ) signaling. In contrast to previous solutions, these results do not increase in complexity as the phase step size decreases. For practical purposes, there is a negligible difference between the exact results and those obtained from an approximate model. This approximate model is used to evaluate the performance of the algorithm with shaped time limited pulses. Jitter, acquisition and symbol slip performance for the second algorithm using NRZ signals are evaluated. It is found that SCCS performs significantly better at small SNR, while Gardner's algorithm can have an advantage above approximately 0 dB.<<ETX>>","PeriodicalId":146674,"journal":{"name":"IEEE WESCANEX 93 Communications, Computers and Power in the Modern Environment - Conference Proceedings","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115240630","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}

One technique involves the injection of possible faults into the network during the training phase. This technique is called the fault injection, or immunization, technique, because of the resulting improvement in the immunity of the network to these faults. Another technique involves redundant computations by groups of neurons in a network. This technique is called the redundancy technique. The redundant computations are usually performed in parallel with nominal computations. Simulation studies on the application of the immunization technique to the design of a fault tolerant neurocontroller are presented. The simulation results show that the fault tolerance of a neurocontroller can be improved when training incorporates the immunization technique.<<ETX>>","PeriodicalId":146674,"journal":{"name":"IEEE WESCANEX 93 Communications, Computers and Power in the Modern Environment - Conference Proceedings","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130642701","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}

Data structures such as the list store, the hash table, the symbol table and the stacks were kept in separate modules with only the routines needed to handle them. Routines in other modules may only read and manipulate these data structures through the specified routines. Using this approach, when a garbage collector strategy or method of storing list cells is changed only the store module need be modified. Test programs and measurement strategies were designed for evaluating garbage collector performance in a virtual memory environment. Three garbage collectors have been coded and tested. They are a conventional link reversal marking garbage collector, a conventional recopying garbage collector, and a garbage collector integrated with the system swapper. The implementations are described and their performances are compared.<<ETX>>","PeriodicalId":146674,"journal":{"name":"IEEE WESCANEX 93 Communications, Computers and Power in the Modern Environment - Conference Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128877246","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}
