Values of gases percentage and gas ratio for each defect type are determined. Nomograms and graphical defect areas have been constructed. A comparative analysis of the diagnostic results of the analysed transformers using 9 well-known methods is made. It is established that diagnoses made with the use of different methods may differ significantly from each other as well as from real diagnoses. The given data allow to increase the recognition reliability of the defect type according to the results of the analysis of dissolved gases in oil.","PeriodicalId":235261,"journal":{"name":"2020 IEEE 4th International Conference on Intelligent Energy and Power Systems (IEPS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129064668","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 filter consists of a voltage source inverter on fully controlled switches, capacitor storage, and a first-order three-phase RL filter. The decomposition of the object of study according to the rates of motion of the dynamic system was performed. The fast subsystem is a circuit of compensation current control, the slow subsystem performs stabilization of the capacitor voltage. An asymptotic double-twisting algorithm to control the DC voltage was used. For the current formation, a two-dimensional sliding surface is used, which is a linear combination of the components of two-dimensional vectors - the error of the current of the RL filter and some variable. The double-twisting algorithm to calculate the instantaneous value of this variable was also used. A simulation model is developed and the results of digital experiments are analyzed. A comparison of the proposed strategy with the traditional PI-regulation by the criteria of the duration of the transition process and the coefficient of harmonic distortions in the current consumed from the network is made.","PeriodicalId":235261,"journal":{"name":"2020 IEEE 4th International Conference on Intelligent Energy and Power Systems (IEPS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128733826","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 main direction of such generators using is to study the interaction of thin film layers from semiconductor materials with high-energy electromagnetic pulses and problem of protection elements against electromagnetic pulses development. The most common variant of a nanosecond pulse generator is a cable-based generator. The main element is a charging line in the form of a coaxial cable with 50 Ohms resistance. A mercury reed switch was used as the trigger, which allowed obtaining a voltage pulse rise time no more than 2 ns. In the process of cable discharge on to consistent load, the pulse amplitude is half of cable charge voltage. This type of generator is quite difficult to set up and operate in order to maintain the optimum parameters of their operation. For its control and power supply it has been developed and manufactured an electronic unit based on microcontroller. It provides powering up of charging line with voltage in the range from 40 to 400 V with steps no more than 1 V, implements manual start of a single pulse and automatic controlled operation mode with series of pulses (period from 1 s, up to hours) and provides the necessary indication of operating modes, including high-voltage DC power generation modes. This control device makes it easier for the user to work with charging line for high-voltage research and provide appropriate safety.","PeriodicalId":235261,"journal":{"name":"2020 IEEE 4th International Conference on Intelligent Energy and Power Systems (IEPS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115044693","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}
