The GIS is usually filled with compressed SF6 for electric insulation. When partial discharge occurs, a portion of SF6 will decompose and oxidize in the presence of oxygen and water vapor to form various stable gaseous by-products, including SO2F2, SOF2, SOF4, SO2, S2F10, S2OF10, S2O2F10, SF4, HF and so on. In order to analyze the discharge mechanism, two zone chemical kinetic models are coupled to interpret the chemical process of point-to-plane 50 Hz ac corona discharge. In the plasma region, the electron impact dissociation reactions, electron-impact ionization reactions, electron-impact attachment reactions, radical-radical reactions, and ion-radical reactions are considered. SF6 decomposes into various low fluorine sulfides, which continue to react with the radicals O or OH, produced from the dissociation of H2O and O2. The electron energy is the function of electric field at 300K. In addition, the stable fragments from SF6 decomposition in the plasma region, like SF2 and SF4, diffuse into the main gas volume and react with water or oxygen to produce the feature by-products SO2F2, SOF2 and SOF4. With comparing the variation rules of these decomposition byproducts with time from simulation and the experimental results, the model is verified to be reliable and reasonable. And also, the physicochemical process of SF6 decomposition mechanism under corona discharge can be captured.","PeriodicalId":250717,"journal":{"name":"2017 3rd International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124796004","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}

SM is a deterministic method which is generally used for the local search and PSO is a stochastic population based method used for global search. Thus, this paper combines the advantage of both the methods to refine the solution. Base level search is done using PSO and finally local search is done through SM to improve the overall quality of results obtained. The proposed approach is tested on multiobjective economic emission load dispatch problem and the results obtained are then compared with other available methods to show its quality and robustness. Price penalty factor method is further used to convert this multiobjective optimization problem into single objective problem. Multifuel options, valve point loading effect and transmission losses are also included in the load dispatch problem to give the practical aspect to the problem. Quality analysis is also done against classical PSO method to show the robustness of the proposed method.","PeriodicalId":250717,"journal":{"name":"2017 3rd International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"58 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123302661","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}

Such systems comprise of healthy operational transformers that are continuously being monitored for their functionality and operational conditions. Transformer Asset Management (TAM) defines the monitoring activities and responsive actions taken to protect the reliability of power systems against the transformers failure. Failure of transformers primarily occurs due to the aging of the oil-paper insulation system. One of the recently used transformer assessment techniques in the TAM industry is the Health Index (HI). The HI value mainly indicates the condition of the transformer in question based on the insulation strength. A set of insulation condition tests/parameters for transformer oil samples is used to compute the HI value. The combined cost for conducting such tests would be expensive for a vast number of transformer oil samples. The objective of the presented work is to reduce the HI cost by reducing the number of required condition tests. Such an objective is achieved with the use of artificial neural networks (ANN) for HI prediction, and feature-based exhaustive technique for eliminating the least significant tests.","PeriodicalId":250717,"journal":{"name":"2017 3rd International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"701 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116099349","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 direct approach of performing symbolic computation using software such as Maple becomes severely restrictive, because, the memory and computational time required increases unboundedly, even for moderate-sized networks. So, handling large-sized ladder networks are ruled out. To circumvent this bottleneck, authors propose an entirely numeric approach, i.e., a symbol-free method to compute any network function (e.g. transfer or driving-point), which is time-efficient, poses no restrictions on the network-size and the number of windings that can be included. Furthermore, it includes both winding and dielectric losses and every inductor and capacitor is coupled to every other inductor and capacitor, thus making it fully-coupled. Details of its formulation are described and simulation results are presented to demonstrate its time-efficiency and applicability to both single- and three-phase winding configurations.","PeriodicalId":250717,"journal":{"name":"2017 3rd International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132530637","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}
