• PAYMENT TRANSACTIONS’ ENERGY EFFICIENCY

  Publication

  • T. Osadcha
  • O. Melnychenko

  - Współpraca Europejska - Year 2021

  The payment system and infrastructure is a sector that is not given enough attention today in the context of energy efficiency. This sector plays a big role in organizing and ensuring money circulation and funds. It has its value consisting on the one hand of the cost of payment equipment, infrastructure, payment instruments. On other hand, its value consists of the cost of energy for their manufacture and maintenance. The European...

  - Year 2013

  In this paper energy efficiency in electric drives is analysed. This factor strongly depends on energy parameters - efficiency n and power factor k (in special case cos fi)

• Losses and energy efficiency of drive motors and systems

  Publication

  • Z. Paszota

  - Polish Maritime Research - Year 2013

  Losses and energy efficiency of every drive motor must be presented as functions of physical quantities independent of losses in the motor. Such quantities are speed and load required by the machine or device driven by the motor, changing in the drive operating field. Speed and load of the motor decide of the instantaneous useful power of the motor and also in a differentiated way of kinds and values of losses occurring in the...

• Energy efficiency of electric multiple units in suburban operation

  Publication

  • A. Jakubowski

  - Year 2023

  This thesis presents approach to analysis of energy efficiency of a suburban rail network, using novel models developed on the Matlab/Simulink basis. Necessary features and requirements for such models were determined thru in-depth review of the source literature in all applicable fields: electrified transportation systems, electric multiple units construction, vehicle drivetrains and finally, existing simulation methods. Existing...
