Types of electrical drives for powered wheelchairs, that are available in the market in most cases have mechanical gearbox, which strongly limits the recuperation of the energy from the electrical machine during, for example, braking. This makes powered wheelchair less effective and increases the weight of the electrical drive, so the use of direct drive in case of assisting powered wheelchair is critical. In order to solve these problems, new modular electrical machine is proposed, which is three phase segmented permanent magnet synchronous motor (PMSM). Design view and schematics of novel electrical machine are proposed in this paper. To predict behavior of a novel modular PMSM, a pilot sample is made on basis of an existing PMSM for bicycle application which is modified by dividing it's stator into segment elements. In order to control electrical drive, power electronics driver is needed.","PeriodicalId":317349,"journal":{"name":"2019 IEEE 60th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"92 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":"130899947","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}

Estonia has set a target to increase the consumption from renewable energy by 2030 to 50%, which would mean that there is a need for about additional 2.3 TWh of electricity generated from renewables by 2030. The maximum flexibility of the existing energy system in integration of renewable energy is not yet analyzed. The EnergyPLAN software is used in the study to determine what is the technical-economical limitation of additional wind and photovoltaic that can be added to the system. The results demonstrate despite the additional renewable energy generation the conventional oil shale based power plants which are mostly influence by the CO2 price. Even when the Estonian 2030 renewable energy targets would multiple the renewable energy production, because of the high CO2 price Estonia would transform to electricity importing country.","PeriodicalId":317349,"journal":{"name":"2019 IEEE 60th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"27 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":"126214300","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 goal of the paper is to specify tasks required for a specialized unsupervised prognosis and control platform for energy system performance estimation.
