The so named “without-fuel” generators as the convertors of the different views of energy of the ether are described. Their elaboration becomes the more and more perspective business for solution of the modern energy problems. Their technical projects are passing to the state of the industrial production. According to the physical signs of the principle effectiveness, heat generators, magnetic dynamic convertors, convertors of gravitational energy and, finally, electrodynamics alternators are distinguished among them. In comparison with heat generators, the class of alternators using permanent magnets is more numerous and diverse. Convertors of gravitational energy are, as a rule, \"perpetuum mobiles\" containing structural components in which falling vertically downward weights or water are rotating the wheel, producing useful work. The selected group of the without-fuel generators is the electrodynamics alternators, working as convertors of the electromagnetic energy from the ether of the surrounding space. The most interesting example of electrodynamics alternators is the \"transformer Tesla\" known to a wide range of specialists. Its distinctive feature is an unusually high energy conversion coefficient (k > 1000), much higher than the transformation ratio due to the inductive coupling between its windings. In conclusion, based on a comparison of analogs, a hypothesis on resonant phenomena as \"keys\" of access to ether energy in the surrounding space is formulated.","PeriodicalId":186321,"journal":{"name":"Lighting engineering and power engineering","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124210756","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}

Despite the large number of developed methods to address this issue, their adequacy depends on the accuracy of identification of the parameters of the schemes of replacement of elements of the electrical network. In this regard, the article considers the problem of identifying the parameters of equivalent schemes of replacement of the power system, mixed passive and active loads, taking into account the sources of electricity in their composition. Two approaches were considered to obtain the initial data on parametric identification. The first of them is based on local measurements of the parameters of the electrical network. The second - on distributed measurements. As a result, the areas of solution of this problem for each of the types of organization of measuring systems taking into account the active intervention in the operation of the electrical network are identified. Methods of approximate calculation of parameters of passive mixed load substitution schemes in three-phase three- and four-wire electric networks, which are based on local measurements, are determined. Methods of exact calculation of parameters of schemes of substitution of electric power system and active mixed loading which are based on the distributed measurements are defined. In addition, the requirements for the organization of a distributed measurement system, which are based on the use of a full-fledged system of SmartGrid with additional application of methods and tools of vector measurement and system of SCADA.\u0000Key words - point of common connection; equivalent substitution sema; identification of parameters of the substitution scheme; mixed load; power system.","PeriodicalId":186321,"journal":{"name":"Lighting engineering and power engineering","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130709922","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}
