Investigation on wheel-sets slip and slide control problems of locomotives with AC traction motors
Santrauka
The article is dedicated to the solution of drive parameter adjustment and correction problems of AC traction motors. Having assessed different rail adhesion ratios and AC electrical machine operation peculiarities, there have been proposed new dynamic slip and slide process control methods to DC/AC, AC/AC current system locomotives. There is described the influence of mechanical characteristics of AC traction motors to the formation of wheel slip process and there are provided structural control schemes of the dynamic slip process. The slip process formation and control conditions for wheel pairs are provided in mathematical and graphical forms. There are provided automatic control parameters of dynamic slip and slide process for AC/AC current locomotives.
