With the incremental modification of the power converter, which feds the induction motor of the compressor, the sizes of the input filters were reduced in order to increase reliability and price. This results in significant increase of the current consumption at the frequencies of 275 and 325 Hz used by collision prevention system of Russian subways. Possible solutions to the problem were considered and a strategy for active elimination of these harmonics was proposed. It ules constant power controller for the compressor drive that decreases 25 Hz harmonic produced by the load torque; thus, 300 Hz ripple from the rectifier at the traction station do not interfere with power ripple caused by mechanical of compressor. Therefore, subharmonfcs of 275 and 375 Hz were decreased and do not affect operation of the collision prevention system The proposed control strategy is presented, it was implemented, and experimental results are provided.","PeriodicalId":192943,"journal":{"name":"2018 IEEE 59th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117197536","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 developed search algorithm divides the search into two: first, the search is „arrowed based on simplified assumptions, and second, a filtered search algorithm is used to find the optimal set of bids.

An electric drive system for throttle control of a centrifugal pumping plant is proposed. The drive system consists of a stepper motor, pump, pipeline, pressure regulation valve, fluid reservoir, and control equipment. The system is developed to provide the possibility for smooth and reliable positioning of a ball type valve for a centrifugal pump. To evaluate the developed electric drive, a series of tests have been conducted. Tests proved that the designed system is accurate at the throttling control mode. The electric drive can be used both for pressure and flow regulation and at the same time can provide a relatively simple way for remote monitoring of valve position that can be installed along the pipelines in the water distribution system. The control system is based on the Arduino board hardware with a custom firmware developed for this particular system.","PeriodicalId":192943,"journal":{"name":"2018 IEEE 59th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133290969","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}
