Under excessive condition, electric arc may occur in the transformer oil. The electric arc may reduce the performance of the transformer oil. This paper explains the experimental results on the effects of electric arc on the partial discharge (PD) inception, the dissolved combustible gases and chemical characteristics of mineral transformer oil. In the experiment, electric arc was generated under AC voltage using needle-pale electrode system to produce highly divergent electric field. The arc treatment was adjusted by the distance between electrode and the duration of arc application. The experimental results showed that arc treatment significantly reduced the PD inception voltage. The electric arc also intensively produced combustible gas such as methane (CH4), hydrogen (H2), ethane (C2H6), ethylene (C2H4) and acethylene(C2H2). The concentration of released combustible gases from the lowest to the highest is C2H6 → CH4 → H2 → C2H4 → C2H2. The concentrations of the last 2 combustible gases are much higher than the others. The results indicated that ethylene (C2H4) and acethylene(C2H2) are the finger prints of the arc in transformer oil. From FTIR spectroscopy it was found that electric arc significantly reduced the aliphatic (C-H) content indicated by the increase of transmittance at wave number of 3000-2850 cm-1. The experimental results also clearly indicated the strong correlation between the reduction of aliphatic (C-H) content and the total combustible gases (TCG).","PeriodicalId":303729,"journal":{"name":"2012 International Conference on Power Engineering and Renewable Energy (ICPERE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129139181","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}

In the first stage, a dc-dc convertor boosts the dc voltage and then, the increased dc voltage turn into ac voltage using an inverter. This topology has two major problems. First and foremost, the overall reliability of system declines. More importantly, multiple problem of using large electrolyte capacitor, which reduces the overall lifetime of the system, leads us to eliminate them. Consequently, integrating boosting phase and inverting phase in one stage is suitable. Also there is another significant problem with PV-Modules. Some times of the day, required radiation intensity for the PV-Modules decrements results in a reduction of the output voltage of the converter which is not desired from the power quality point of view. In this paper a new topology is suggested in order for increasing the power quality of grid-connected PV-Modules. A current source boost inverter (CBSI) is utilized for this aim. Major advantage of this CBSI, is its low-loss switching pattern which results in its better efficiency.","PeriodicalId":303729,"journal":{"name":"2012 International Conference on Power Engineering and Renewable Energy (ICPERE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124121525","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}

A maximum power point tracking (MPPT) algorithm is used in order to obtain maximum power under different sun irradiance from PV; hence, in the darkness the system is used as an active filter and in the sunlight the system operates as both power conditioner and shunt active filter simultaneously. Control of the presented system is based on instantaneous power theory (p-q theory) and adaptive hysteresis band control (AHBC). Unlike conventional fix band hysteresis control in which instantaneous switching frequency is not constant, by changing hysteresis band in the AHBC method, instantaneous switching frequency will be constant with a little deviation. Simulation results using MATLAB/SIMULINK verifies effectiveness of the system in injecting of maximum power captured by the PV system to the grid and compensating of the harmonic currents and reactive power of the nonlinear load.","PeriodicalId":303729,"journal":{"name":"2012 International Conference on Power Engineering and Renewable Energy (ICPERE)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125224188","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}
