Integral formulas are obtained to determine the applied unbalanced power components, making it possible to record their contribution to the deterioration of electrical energy quality. The relationship between power unbalance components and the linear unbalanced load parameters was established to verify the above-mentioned integral formulas by computer experiment. Experimental studies show complete coincidence of the measured power points with the curves of the calculated dependences. It has been found that with given source symmetric voltages, the three-phase sinusoidal process of the unbalanced load is fully identified by four scalar values: active and reactive powers and applied orthogonal components of the unbalance power. These scalar variables can be used to synthesize control signals for distributed active filters of intelligent local power grids.","PeriodicalId":432063,"journal":{"name":"2022 IEEE 8th International Conference on Energy Smart Systems (ESS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122643497","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}

Estimation of fault's distance is carried out based on line's operating mode parameters (namely phase currents and voltages to ground) at the start of the line. Fault's distance calculation is implemented using vectors of line's operating mode parameters from both sides of the line. Verification of the method has been conducted experimentally as well as via math modelling. Method's errors were caused mostly by small currents' value alteration in case of fault, existence of resistance at fault's location and power line's load resistance change. Research about impact on method's accuracy due to distance to the fault as well as resistance value at the fault location has been carried out.","PeriodicalId":432063,"journal":{"name":"2022 IEEE 8th International Conference on Energy Smart Systems (ESS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126928002","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 high level of technical complexity of networks, strong branching, combined with a large number of elements operating in a little predictable mode, make the management of the modes of such networks a rather difficult task, which requires a large amount of information regarding the parameters and modes of electrical networks and their elements, as well as the use of a large number of corrective elements. However, the lack of scientific foundations and automated control of the modes of urban electrical networks as a whole significantly complicates the solution of this problem, and taking into account the characteristics of urban electrical networks, the distribution of parameters in space, and processes in time and the influence of network regimes on the socio-economic conditions of residents, under these conditions, make it almost unsolvable. Considering the above, the authors have developed the scientific foundations for the automated control of modes of urban electrical networks, based on the use of distributed multi-level control systems built according to a hierarchical principle, in combination with the use of corrective multifunctional devices in load nodes, built on the basis of phase-switching systems. Their use in combination with the use of the Smart-Grid concept opens up the possibility of automatically changing the module, phase shift and harmonic composition of voltages and currents in load nodes, ensuring the optimal functioning of urban electrical networks as a whole, by reducing voltage and power losses in networks.","PeriodicalId":432063,"journal":{"name":"2022 IEEE 8th International Conference on Energy Smart Systems (ESS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126493698","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}

Solving this problem should contributed to more efficient management of power companies resources and increase their competitiveness. This paper proposes an approach to quantitative assessment of technical condition for power transformer using an integrated technical deterioration index. The proposed approach is based on fuzzy logic and fuzzy set theory. This allows you to formalize expert assessments of defect development in power transformer. The formalization of technical condition evaluation for power transformer in knowledge base form is implemented in expert system prototype. The integrated technical deterioration index of power transformer was determined based on test results of technical condition parameters for functional units of power transformer using expert judgments. The considered approach to uncertainty formalization about technical condition of power transformer allows constructing the deterministic scheme of decision-making on further service strategy. The procedures of ranking, out of service of specific objects are implemented based on objective criteria in this service strategy of power transformer.","PeriodicalId":432063,"journal":{"name":"2022 IEEE 8th International Conference on Energy Smart Systems (ESS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133479041","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}

Vacuum monitoring sensors are used for this purpose. Modern sensors are quite complex and expensive electrical devices. In some cases when the object operated under vacuum is partially or completely made of plates and shells, these components energy capacity can be used for vacuum control without engaging the special sensors. In particular, such control systems are used in packaging with vacuum cans. Studies have shown that membranes stamped on the body of an object function due to the transformation energy that occurs therein as a result stability loss from pressure drop.
