The routers are designed with high-frequency solid state transformers. The article deals with the issue of the smart grids construction possibility based on controlled power routers. The article presents the results of non-railway consumers power supply systems operation modeling where the system is connected via the power router and consists of distributed generation plants operating based on the renewable energy resources. The research was carried out with the application of simulation modeling packages Simulink and SimPowerSystems of the MATLAB system. The research results allowed shaping of the following conclusions: the power router enables a successful riddance of power quality problems while ensuring a reliable integration of distributed generation plants into the power supply system inclusive of the implemented plants based on renewable energy resources; when connecting distributed generation plants to the power router, one has to consider a visible increase in the short circuit currents in case of grids 0.4 kV damaging; the application of the power router allows limiting short circuit currents compared to a traditional transformer, and decreasing in the voltage dip value in case of a remote short circuit.","PeriodicalId":263504,"journal":{"name":"2018 International Ural Conference on Green Energy (UralCon)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133977958","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}

Nowadays, wind energy plays an important role in generating green and cheap electrical power. Scientists improve the strategy to optimize the usage of this type of energy by different techniques. A doubly fed induction motor (DFIM) becomes a necessary part of the wind turbine generation system due to its good efficiency of using the wind power and controlling the reactive power. Due to irregular obtainability of the wind, a power system is intended to extract a maximum power from the wind. The purpose of this paper is to introduce a control strategy of a maximum power point tracking (MPPT) for a wind turbine and to study its steady state behavior by using MATLAB/SIMULINK. This modelling algorithm gives the asynchronous machine a possibility to trace and follow the path of maximum power extraction and support the optimal operation points of the power coefficient curve over different wind circumstances, also simulating the wind turbine (WT) model and studying the steady state condition for the reference value and actual value for the rotor speed, electromagnetic torque, the two components of rotor current, rotor voltage, stator voltage and the value of currents for the rotor and stator sides.","PeriodicalId":263504,"journal":{"name":"2018 International Ural Conference on Green Energy (UralCon)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129306541","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}

Possible methods for determining optimal parameters of the water supply system for protection from freezing are described. The requirements for the physical model of the pipeline system are substantiated, taking into account the dynamic change in the volumetric flow rate and the water temperature in the line. The description of the laboratory stand allowing simulating various operating modes of the first rise section is given. The hydraulic characteristics of the water supply system are experimentally determined when the frequency of the supply voltage of the pumping unit changes. Experimentally, the level of the electric power consumption is defined by the pump unit at the maintenance of the required volume flow by the method of frequency regulation.

At the present time improving the efficiency of cogeneration station is one of the priority goals in the development of district heating. One of the most perspective options for improving the efficiency of cogeneration station is to reduce the temperature of the heat network schedule, with the greatest effect can be achieved by applying individual systems with heat pumps for the thermal energy consumers as final heaters. However, existing solutions require significant capital expenditures. Thus, for the implementations of existing projects the technology is required, allowing to organize the gradual installation heat pumps in heating systems with low cost. As a starting stage of heat pump introduction, the compensation of hot water supply load in the non-heating period is offered. For this purpose the authors developed a universal system for the compensation load of hot water supply, which is a cost-effective and relatively affordable way to initial exploitation of heat pump in a district heating. The system is based on a block containing a heat pump with circulation pumps. The system allows using heating appliances as a heat exchanger to capture excess heat building premises.
