   Design Criteria for Energy Efficient Pump Drive Systems

[Download]

Abstract: In this paper we present a guide to choose an energy efficient configuration of a pump drive system inan early stage of design process based on an user-defined load profile. All subsystem models are brieflypresented, including different control methods (speed and throttle control) and single or cascaded pumpdrives. These models are based on free accessible parameters of data sheets. The analysis regarding thepower losses leads to the Selection Diagram. This diagram enables the fast selection of an appropriatepump drive topology, using only a few practical design criteria.

Abstract: After the 3.11 earthquake in Tohoku district in Japan, energy saving and renewable energy utilization become one of the important problems in Japan. East Japan Railway Company, as a public transportation company, tries to contribute to solve these problems by realizing eco-friendly railway transportation system. In this paper, three realized and under construction projects are summarized which enhance efficiency of traction power supply system. First project is installation of lithium ion battery at Haijima Substation on February 20th, 2013 to make use of regenerative power in d.c. traction power supply. Second project is the power conversion application to be installed at Ushiku sectioning post for a.c. traction power supply and will start operation in the end of 2013 fiscal year. The last project but not least one is “zero-emission station” realized at Hiraizumi Station on June 28th, 2013. The total electric power of the station is supplied from solar power even in the evening using lithium ion batteries. The detail of the operation data of “zero emission station” is shown in this paper.

   State of the technology of power loss determination in power converters

Abstract: Power loss determination is commonly done in industry and research institutions by means of three basic methods, the electrical measurement of input and output power, the calorimetric measurement and the single component power loss determination based on data sheets or measurement. All of these methods are characterized by different measurement accuracy and by a different effort for the measuring systems. To achieve a required minimum measurement accuracy with limited effort the determination method and measuring systems have to be carefully chosen. These methods are presented and characterized, their limitations are shown and t compared. By this, support for the choice of suitable method, depending on the application, is given.
