Instead of the circuit complex model, reduction of the computing effort implies using a macromodel capable to capture the behaviors of the original circuit while preserving its essential properties. Building such a model is based on a simplified and unitary description of the circuit, by establishing a simple relationship between the input/output variables. In this paper, the model order reduction techniques based on method projection in Krylov subspace are presented in two implementation: on state equations and on semi-sate equations of the analog circuits. Illustrative simulations are performed that allow a comparison of the standard methods based on Padé approximation with Krylov subspace methods, and some important conclusions.","PeriodicalId":239366,"journal":{"name":"2010 12th International Conference on Optimization of Electrical and Electronic Equipment","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126636528","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 degree of interconnection increased, and local networks became parts of wide area power systems. As part of the need to upgrade the existing networks in order to cope with the new operating conditions, the concept of smart grids was proposed. A part of such a smart grid is a real time monitoring and control system, based on digital equipments. This paper proposes a method of improving the results of a distributed estimated algorithm by using REI equivalents for a more accurate representation of the influence of the remote system on a local subsystem, and synchronized voltage measurements provided by phasor measurement units installed in key points from the grid.","PeriodicalId":239366,"journal":{"name":"2010 12th International Conference on Optimization of Electrical and Electronic Equipment","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126965942","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}

These species are responsible for a noticeable abatement of the pollutant concentration, even of recalcitrant compounds. The relevant kinetics are examined with special emphasis on Temporal Post Discharges Reactions which develop in the solution after the discharge is switched off and without supplying extra energy. The moieties responsible for this feature are discussed and arguments favour H2O2 and peroxynitrous acid. ONO2H, which degrades lipoproteins is probably involved in the attacks at the bacterial membranes causing the death of the microorganisms. TPDR are also identified in case of bacterial inactivation. Plasma activated water induces inactivation of bacterial colonies even 24 h after the plasma treatment.

This paper proposes an algorithm to generate the optimum d- and q-axis reference currents for four quadrant operation of PMSMS drive system, for wide speed range, that is fed by PWM inverter equipped with diode rectifier front-end. The algorithm offers the optimum torque capability for the PMSMS despite significant changes in dc link voltage and machine parameters. This algorithm can be easy integrated in the field oriented control of PMSMS with or without mechanical sensors, but also in the scalar control algorithm. The algorithm identifies when the machine enters in the flux weakening region and also adjust the d- and q-axis reference currents and the limits of the PI speed controller according to the dc link voltage and the operating mode. In the motor mode a PI voltage controller generates the d-axis reference currents, while in the generator mode the power is dissipated in the machine and a PI overvoltage controller increases the d-axis reference current and limits the q-axis current. The experimental results show that the proposed algorithm provides good steady state and dynamic performance.","PeriodicalId":239366,"journal":{"name":"2010 12th International Conference on Optimization of Electrical and Electronic Equipment","volume":"110 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114003887","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}
