Abstract
Instalatia asigura alimentarea excitatiei motoarelor sicrone, de asa maniera, încît motorul sincron sa furnizeze curent capacitiv, necesar altor consumatori alimentati din aceeasi retea sau sa functioneze cu curent minim, urmarind vîrfurile curbelor în V ale masinii. Instalatia se compune dintr-un redresor comandat prevazut cu regulatoare automate. primul regulator, de stabilizare a curentului capacitiv, primeste un semnal pentru curentul capacitiv prescris si altul de la un dispozitiv de masurat curent reactiv, I sin fi conectat la bornele motorului sincron. Al doilea regulator, subordonat primului, regleaza curentul de excitatie, limitîndu-l superior. în cazul scaderii tensiunii de alimentare a motorului sincron, pentru ca motorul sa functioneze în continuare pe portiunea stabila a caracteristicii cuplului, este necesara majorarea curentului de excitatie, lucru comandat automat prin întreruperea legaturii dintre regulatoare si aplicarea unei alte valori prescrise pentru curentul de excitatie. Pentru ca masina sa functioneze cu curent minim, se prescrie curent capacitiv zero. în cazul pornirii motorului în asincron pentru sincronizare, se ia semnal de la dispozitivul de masurat curent reactiv I sin fi.The plant provides power to the excitation of the sicrone motors in such a way that the synchronous motor delivers capacitive current to other consumers powered by the same network or to operate at a minimum current, following the tops of the car's V curves. The installation consists of a controlled rectifier with automatic regulators. the first regulator, the capacitive current stabilizer, receives a signal for the prescribed capacitive current and the other one from a reactive current measuring device, it is connected to the synchronous motor terminals. The second regulator, subordinate to the first, regulates the excitation current, limiting it to the higher. if the synchronous motor power supply voltage drops to keep the engine running on the fixed torque portion, an increase in excitation current is required, which is automatically controlled by disconnecting the regulators and applying another setpoint for the excitation current. In order for the car to operate at a minimum current, zero capacitive current is prescribed. In the case of starting the asynchronous motor for synchronization, a signal from the reactive current measuring device I will be taken.
