Abstract
Способ повышения коэффициента мощности асинхронного генератора с короткозамкнутым ротором при работе параллельно с сетью, отличающийся тем, что, с целью повышения эффективности его работы, проводится перераспределение реактивной и активной составляющих тока внутри каждой фазы асинхронного генератора; реактивная составляющая тока фазы уменьшается путем уменьшения линейного напряжения сети относительно номинального линейного напряжения генератора на одну ступень из расчета: , тем самым создается возможность увеличения нагрузки генератора; активная составляющая тока фазы увеличивается в пределах номинального значения тока фазы при работе асинхронного генератора путем увеличения мощности, подводимой к валу асинхронного генератора со стороны его приводного двигателя энергетической установки для преобразования механической энергии в электрическую. A method of increasing the power factor of an asynchronous generator with a squirrel-cage rotor when operating in parallel with the network, characterized in that, in order to increase the efficiency of its operation, the reactive and active components of the current are redistributed within each phase of the asynchronous generator; the reactive component of the phase current is reduced by decreasing the line voltage of the network relative to the nominal line voltage of the generator by one step from the calculation: thereby creating the possibility of increasing the load of the generator; the active component of the phase current increases within the nominal value of the phase current during operation of the asynchronous generator by increasing the power supplied to the shaft of the asynchronous generator from the side of its drive motor of the power plant to convert mechanical energy into electrical energy.
