The objectives of this work were to monitor and record the temperature data of salt solution in the PSTC system and to control the circulating water pump flow based on the targeted temperature. The PSTC system was used as a supporting system to pre-heat the salt solution until the it reaches the desired temperature. This was monitored by a DS18B20 waterproof temperature sensor. The real-time data was then be displayed on an LCD, saved in a microSD card and via smart phone. An Internet of Thing (IoT) of Blynk Applications and data logging systems were utilized. The energy and the separation performance of the integrated system was also investigated. The highest temperature attained by the PSTC system based on the conducted experiments was above 60°C. Based on the results, a fluctuation of energy consumption by the integrated system was observed. This was due to the supplementary energy supplied by the solar collector system. The integrated system also exhibited a moderate separation efficiency with maximum permeate flux of 3.5083 kg/m2.h and salt rejection of 93.96%. As a conclusion, the PSTC system integrated with MD system can surely bring a lot of benefits for the desalination industry. Additionally, IoT can be employed in the future as means to accurately monitor solution temperature for such integrated systems.","PeriodicalId":235261,"journal":{"name":"2020 IEEE 4th International Conference on Intelligent Energy and Power Systems (IEPS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128498746","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}

It allows to choose the optimal geometry of the elements of the water passage at the initial stages of designing a new reversible hydraulic machine or modernizing an existing one. This method has proved positive in the numerical study of high-head reversible hydraulic machines at pressures of 200 and 500 m. Using the method of non-dimension averaged parameters in calculation it is necessary to have geometric parameters only in the specific cross-sections of the water passage. This is very effective in terms of saving time and computational resources. In the course of the work, three variants of the water passage of the high-head low-speed reversible ORO500 hydraulic machine were investigated. As a result, it was determined that the geometry of the water passage’s elements significantly effects the hydraulic machine’s parameters. The highest losses value (62 %) is in the inlet (spiral casing with stator and wicket gate). Therefore, the parameters of these elements were changed. Hydraulic efficiency increased by 1.16 % results from changing the parameters of the spiral casing (increasing the average flow angle by 100). Changing the geometry of the wicket gate leads to additional increasing of efficiency by 0.84 %.","PeriodicalId":235261,"journal":{"name":"2020 IEEE 4th International Conference on Intelligent Energy and Power Systems (IEPS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133223697","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 primary stage of the converter is a traditional full-bridge voltage-source inverter (Voltage-Fed, VF) based on IGBT with reverse diodes shunted by snubber capacitors. The secondary stage is based on IGBT with reverse diodes full-bridge Current-Fed (CF) inverter and a bidirectional four-quadrant power switch (FQS) based on two IGBT with reverse diodes is connected in series with the transformer. For the energy transfer mode from the VF stage to the CF stage, a separated-commutation switching algorithm that provides a zero current switching (ZCS) turn-off mode and an inductive snubber turn-on mode for the CF switches, and a zero-voltage-switching (ZVS) and capacitive snubber turn-off mode for the VF switches is described. Leakage inductance of the transformer is used as an inductive snubber. When the transistors of the VF stage are turning-off, an additional, in comparison with the known solutions, forced switching-on of the CF stage main transistors on the interval of half-period provides a resonant overcharge of the snubber capacitors. This ensures the ZVS mode of turning on of the VF stage transistors in a wide range of load current changes, up to idle mode. The proposed ideas are verified with simulations in MATLAB. The topology is proposed for high power battery energy storage systems.","PeriodicalId":235261,"journal":{"name":"2020 IEEE 4th International Conference on Intelligent Energy and Power Systems (IEPS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129582120","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}
