The negative factors contributing to the voltage deviation at consumers’ connection points are analyzed. It’s shown that voltage control using only on-load tap changers on primary substations can be insufficient in case of long-length and heavy loaded feeders. Paper describes conditions when booster transformers are to be installed and conditions when can be effectively used local voltage control on distribution transformers. Conclusions are made about the need of using various means of voltage control on different network levels depending on network structure, load flow parameters and time-domain voltage profiles.","PeriodicalId":272476,"journal":{"name":"2021 3rd International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131955716","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}

Examples of the use of a neuroregulator in a single-circuit ASR with objects of different time characteristics are given. The studies were carried out using actuators and pulse-width modulators in the calculations. It is considered in comparison with a single-circuit control system without the input of an additional signal. The expediency of using neuroregulators in existing regulatory systems is determined. This article discusses neuroregulators that include 6 and 7 artificial neurons. The chosen model is quite simple in software implementation and is useful in experiments. The software implementation of the model of the system under consideration was performed in the Mathcad software. It is planned to implement the considered system on a laboratory stand. To evaluate and conclude conclusions on the modeled processes of managing the regulated object, the quality indicators of regulation were calculated for comparison.","PeriodicalId":272476,"journal":{"name":"2021 3rd International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131325849","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}

For this reason, amplitude and phase spectrum accurate measurement is of the utmost importance. Discrete Fourier transform is most commonly used to measure the complex spectrum. The complex spectrum measurement error is associated with so-called “spectrum leakage” effect. The paper proposes a method to compensate of the “spectrum leakage” effect, based on additional frequency measurement and calculation of tuning coefficients for complex spectrum. The features of the application of the proposed method for the case of sinusoidal and polyharmonic signals are considered. Modifications are proposed for the case of applying the fast Fourier transform algorithm (FFT) and Goertzel algorithm. Analytical relations are obtained, which make it possible to estimate the amplitude and phase spectrum measurement error. By applying Matlab, simulation modeling has been performed, which makes it possible to evaluate the effectiveness of proposed technique.","PeriodicalId":272476,"journal":{"name":"2021 3rd International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133033461","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 experiments were conducting with different subcoolings to the saturation temperature under atmospheric pressure. Ethanol-water mixtures (40% and 60%) were used as cooling liquids. The working sample was a nickel cylinder.
