Pantograph-Catenary System Modeling Using MATLAB-Simulink Algorithms
Scientific Journal of Riga Technical University. Computer Sciences, 2010 Pantograph-Catenary System Modeling Using MATLAB-Simulink AlgorithmsContacts between pantograph and catenary are the most critical parts in the transmission of electrical energy for modern high-speed trains. Contact wire oscillations change combined force between pantograph and catenary, and the contact may even get lost.
