Optimal System for the Compensation of the Reactive Power with Synchronous Motors

In the activity of some factories that use synchronous motors it’s nec-essary to chose and maintain the most rational value of the reactive power provided by the synchronous motors. In the context of the reduction of the energy consumption and knowing that the power of the synchronous motors is relatively great in the air compressor stations, the approach of the optimal regime of functioning of the synchronous motors, concerning the energy consumption, is necessary. Considering the synchronous motors together with the other consumers fed from the same bars and the feeder cable a functional utility, in the paper as optimising is presented the working regime that assures, on the defined above assembly, the minimal losses of energy
