Keywords:
synchronous motor, reactive power, superexcitation, rotor winding loss, steel core magnetic loss, electromagnetic torque, static stabilityAbstract
The article presents data that during the operation of synchronous motors at metallurgical enterprises, they give reactive power to the electrical network when switching to overexcitation mode, which, as a result, contributes to an increase in the value of cosjн in the part of the network connected to the load. For this reason, a method for designing synchronous motors for operation at rated power during overexcitation and in the case of cosjn=0.9 is considered, which creates the possibility of energy saving.
