Of paramount importance to the success of any VE is realism; entities must move and behave believably and approximate the complexity of the real world. Such real-world fidelity is accompanied by the challenge of making immersive training in virtual reality (VR) more widely available, at costs significantly less prohibitive. A solution is presented to recreate the VE on low-cost PCs, reducing the cost of the VR software itself, yet preserving real-time performance. This paper presents a low-cost, PC-based VR development system within the framework of ESOPE-VR, a VR power station operator training simulator (OTS) prototype for power-utility personnel. PC-ESOPE-VR aims to provide the same or improved functionality and performance as the original, with a 3-D visual interface, voice recognition and feedback, navigation and manipulation facilities and expert system, multimedia and multi-user (distributed) support, yet address the practical demands raised above. The PC-based system is also compatible with the original; it can draw on existing ESOPE-VR power component libraries and support the automatic synthesis of a virtual power station environment from its single-line diagram representation. The approach used towards fulfilling all these issues is described, followed by key implementation results.","PeriodicalId":383749,"journal":{"name":"Proceedings of the 20th International Conference on Power Industry Computer Applications","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123659341","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}

From the fault location equations, similar to the conventional approach, this method selects phasors of prefault and superimposed voltages and currents from all phases of the transmission line as inputs of the artificial neural network. The outputs of the neural network are the fault position and the fault resistance. With its function approximation ability, the neural network is trained to map the nonlinear relationship existing in the fault location equations with the distributed parameter line model. It can get both fast speed and high accuracy. The influence of the remote-end infeed on neural network structure is studied. A comparison with the conventional method has been done. It is shown that the neural network-based method can adapt itself to big variations of source impedances at the remote terminal. Finally, when the remote source impedances vary in small ranges, the structure of the artificial neural network has been optimized by the pruning method.","PeriodicalId":383749,"journal":{"name":"Proceedings of the 20th International Conference on Power Industry Computer Applications","volume":"349 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122851637","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 final objective is to present timely information about transfer limits and stability margins and eventually implement corrective actions. In this paper, the authors assume that the dynamic contingency analysis (DCA) has to be repeated every 15 minutes. During this period of time, the loading and configuration conditions of the system change significantly but not drastically. They verify that the set of the relevant contingencies remains almost the same in the time interval comprised between two cycles of the functions associated to dynamic security analysis (DSA). Parallel-in-time formulated algorithms can be used in tracking the load conditions in real-time adopting as initial guess for the simulation of each contingency, the trajectories obtained for the same contingency at the previous cycle of DSA functions (that is the ones calculated in the previous 15 minutes). In this way, the information obtained in a previous cycle of DCA is not lost completely as in step-by-step algorithms. The feasibility of the approach has been tested on the Italian 380-220kV transmission system operated by ENEL. A parallel implementation of the approach on a nCUBE multiprocessor is reported.","PeriodicalId":383749,"journal":{"name":"Proceedings of the 20th International Conference on Power Industry Computer Applications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127553256","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}
