To deal with this task, two simulation models of liquid level control in the iThink program were developed. The first model was designed using only a frequency converter, and the second model was using a frequency converter and a Fuzzy Controller. An imitation of the liquid level control process was carried out, and from this graph of pump energy consumption were obtained. Based on the initial and obtained data, a comparative analysis of the effectiveness of the considered control systems was carried out, and the power consumption of the considered control systems of two simulation models of a booster pumping station were also presented in graphical form. The analysis of the models examined showed that it is more economical and safer to use a control circuit with a frequency converter and a Fuzzy Controller.","PeriodicalId":371743,"journal":{"name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114561970","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 switching of the windings is carried out according to the signals of the rotor position sensor and from control system. The time of transient current changes during switching directly depends on the time constant of the windings. In machines of medium and high power, the time constant is significant, which increases the time of transient processes, and at high rotational speeds leads to a decrease in the average current in the winding, thereby reducing torque. An effective means of combating such phenomena are devices accelerating (forcing) transients during switching windings. The article proposes an original forcing circuit for multiphase electric machines and a circuit method for studying the transient time during switching windings. For example, a simulation model of the connection scheme of the windings of a three-phase electric machine with forcing elements is developed and waveforms of currents in the windings showing the effect of forcing are shown.","PeriodicalId":371743,"journal":{"name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132273386","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 negative consequences of the reverse rotation mode of the fan impeller or pump for the electric motor are considered in detail. The article discusses ways of picking up electric drives of fan and pumping units during reverse rotation of the impeller. It is shown that the existing methods for determining the initial speed and the pickup of the rotor are focused on the self-starting of the electric motor when power is lost, at which the rotor rotates in the normal direction. A method for picking up a frequency converter is proposed, which allows to determine the frequency and direction of rotation of the rotor, thereby ensuring the pickup and successful start of the electric motor with the reverse direction of rotation.","PeriodicalId":371743,"journal":{"name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132407355","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}

However, this formation has a significant disadvantage: high sensitivity to non-linear distortions (more often it is intermodulation distortion) arises in amplification paths. It is often very difficult to evaluate the influence of many nonlinear effects by compiling and solving a system of nonlinear integro-differential equations. Therefore, one has to turn to mathematical models. The problems associated with the creation of mathematical models of nonlinear systems form one of the main areas of science and technology – optimization, or modeling, identification and approximation of their transfer characteristics.","PeriodicalId":371743,"journal":{"name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129412429","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}

Optimum value of inductance for two models when value of kinetic energy reaches the maximum level was determined, it influences on escape speed of plasma jet. Analysis of the solenoid inductance was made, it influences on increasing transverse velocity component, and thus, the metal erosion and amount of disperse powders. The system of second order differential equations was written down as first order differential equations for calculation accuracy increasing and was solved using the fourth-order Runge-Kutta fixed-step method. View of potential pit was simulated in software package COMSOL Multiphysics which shows spatial limitation of the plasma particles expansion and illustrates the advantages of the longitudinal and transverse components of the charged particles velocity in the plasma jet.

Therefore, high demands are placed on its design and there is a need to diagnose its technical condition. The most promising method of diagnosis is the method using an instrument analysis of an external magnetic field. In addition, the evaluation of the external magnetic field is relevant in practical verification of the magnetic compatibility of damping electromechanical energy converters. In this regard, the authors developed a mathematical model of an external magnetic field of damping electromechanical energy converters with primary magnetic field asymmetry and considered the possibility of diagnosing them using an external magnetic field. The simulation results analysis showed that the relative displacement of the magnetic symmetry axis of the field from the magnetic system axis could be determined by calculation and as a diagnostic signal in the form of changes in the amplitude of the external magnetic field intensity (envelope).","PeriodicalId":371743,"journal":{"name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"12 Suppl 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134070275","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}
