Abstract

Электрические машины (2) с переменной частотой вращения используются в качестве стабилизаторов в энергосистеме. Вращение ротора (10) соответствует некоторой кинетической энергии, и эта кинетическая энергия используется как накопленная энергия стабилизатора. Электрической машиной (2) и частотой ее вращения управляют, управляя током, который течет через ротор (10). Питание источника напряжения и средств (18) управления, используемых для этого, осуществляют от источника, который не зависит от напряжения в энергосистеме. Предпочтительно, чтобы источник напряжения включал бесщеточную регулирующую машину (20), установленную на одном валу (22) с главной электрической машиной (2). Кроме того, благодаря непосредственному контролю температуры в статорной (14) и роторной (16) обмотках, главная электрическая машина (2) может быть временно использована для передачи мощностей, которые намного превышают ее номинальную мощность.Международная заявка была опубликована вместе с отчетом о международном поиске.Variable-speed electric machines (2) are used as stabilizers in the power system. The rotation of the rotor (10) corresponds to a certain kinetic energy, and this kinetic energy is used as the accumulated energy of the stabilizer. The electric machine (2) and the frequency of its rotation are controlled by controlling the current that flows through the rotor (10). The power of the voltage source and the means (18) of the control used for this purpose are supplied from a source that does not depend on the voltage in the power system. Preferably, the voltage source includes a brushless regulating machine (20) mounted on the same shaft (22) with the main electric machine (2). In addition, thanks to direct temperature control in the stator (14) and rotor (16) windings, the main electric machine (2) can be temporarily used to transfer power that far exceeds its nominal power. The international application was published along with an international search report .
