In order to achieve behavioural modelling, a VHDL description style can be used where the system structure description (fuzzy sets, rule base etc.) and the operator description (connectives and fuzzy operations) are defined separately. It allows describing both the fuzzy system structure and the processing algorithm independently. The description format allows the use of linguistic hedges in order to compact the rules defining the system's behaviour. The paper analyses the potential advantages for the use of bespoke high-level descriptions and the feasibility of the translation into a VHDL code with a GUI interface of a controller described by a fuzzy logic oriented language. This study is encased in a particular application: Lithium-Ion Hybrid Super Capacitors management. The Lithium-Ion Hybrid Super Capacitor is a novel technology breaking new ground in the technology sector. The Lithium-Ion Hybrid Super Capacitor (LIHC) is fast evolving as the missing link between the Electric Double Layer Capacitor (EDLC) and the Lithium-Ion Battery (LIB), is a distinct hybrid of the two technologies. To be effective, it requires a management controller, which the paper targets to produce in a VHDL hardware description language.","PeriodicalId":332414,"journal":{"name":"2020 IEEE 61th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127358212","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}

Adaptive automation of accelerated step start of engines in Autonomous power supply systems for own needs of nuclear power plants 核电厂自主供电系统中发动机加速步进起动的自适应自动化

Some of these electric receivers operate in the normal technological cycle of power generation, while others that are particularly responsible are switched on when an emergency occurs. To ensure the reliability and safety of NPP operation in these operating modes, especially responsible consumers are started in Autonomous power supply schemes with a power source (diesel generator) of limited and comparable power. To ensure the success of the start-up of highly critical electric motors for their own needs, the NPP uses automatic step-start. The speed of a typical, standard automation algorithm is about 50–60 seconds. However, in particularly critical conditions, for example, for the power supply of mechanisms for cooling systems and accident localization, greater speed of this type of automation is required. With this requirement in mind, this article proposes and tests an adaptive algorithm for automatic accelerated step start-up (USP) of specially responsible electric motors for the NPP's own needs. The use of adaptive automatic can reduce the time of successful start-up of all engines, while excluding overloading of the diesel generator and over-regulation of the voltage in the Autonomous power supply scheme for the NPP's own needs.","PeriodicalId":332414,"journal":{"name":"2020 IEEE 61th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115718470","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}

In order to apply these pedagogical approaches to the most appropriate CPS applications, surveys have been performed in Belarus and Ukraine to reveal these major applications. A discussion of the findings of these surveys is included in the present paper and will be taken into account when a number of e-books are developed by the European, Belarusian and Ukrainian partners of the Erasmus+ project.
