Abstract

Inventia se refera la un sistem de comanda pentru un sistem de reglare a unei actionari de mare putere cu motor de curent continuu, cu excitatie independenta, alimentat pe indus printr-un convertor de curent continuu nereversibil, iar pe excitatie cuun convertor de curent continuu reversibil, care asigura, pe baza prelucrarii marimilor de proces - prescrierile de turatie, treapta si rampa, tensiunea pe indus si curentul de excitatie, comenzile de bloarea si/sau deblocare a regulatoarelor si a i mpulsurilor catre convertoare, de descarcare a excitatiei, de trecere a actionarii în "starea de asteptare" (regim de mers în gol economic), eliminând hazardul si asigurând supravegherea protectiei la excitatie minima, în vederea schimbarii sensuluide rotatie prin excitatie cu recuperarea energiei, brusc sau cu trecere prin starea de mers în gol economic. Solutia este destinata actionarilor reversibile.The invention relates to a control system for a high-power DC drive system with independent excitement, supplied to the induction by a non-reversible DC converter, and on the excitation with a reversible DC converter , which assures, on the basis of processing process sizes - speed, step and ramp speeds, induction voltage and excitation current, controlling and / or unblocking of regulators and pulses to converters, excitation discharge, Holders in the "wait state" (economic idle mode), eliminating hazard and ensuring the protection of the minimum excitation protection, in order to change the direction of rotation by excitation with the energy recovery, suddenly or through the economical idle state. The solution is for reversible shareholders.
