Изобретение относитс к способам регулировани мощности первичного двигател турбо- и гидрогенераторов и может использоватьс при их парал- j лвльной работе дл повышени устойчивости энергосистем.The invention relates to methods for controlling the power of a prime mover of a turbo-generator and hydrogenerators and can be used in their parallel operation to increase the stability of power systems.
Известен способ автоматического регулировани мощности первичного двигател генератора со статическим Q регул тором по отклонению частоты.There is a method for automatically controlling the power of a primary motor of a generator with a static Q regulator on frequency deviation.
При регулировании по этому способу параметром регулировани вл етс общее дл всех параллельно работающих агрегатов среднее значение частоты. «с энергосистемы. Поэтому послеаварийное распределение небалансов активной мощности не зависит от удаленности агрегатов от места возмущени , а определ етс их единичной мощное- 2Q тью и статизмом регулировани . При/ этом из-за относительной малости изменени частоты, имеющей место при аварийных небалансах в крупных энергообъединени х , локальный резерв 25 мощности не может быть реализован первичными регул торами в достаточном объеме. Все это вызывает нежелательное изменение заданного режи- ма работы линий электропередач и, зоWhen regulating with this method, the regulating parameter is the common frequency value for all parallel units operating. “From the power system. Therefore, the postemergency distribution of unbalances of active power does not depend on the distance of the aggregates from the place of perturbation, but is determined by their unit power and control statism. At this, due to the relative smallness of the frequency change occurring during emergency unbalances in large power interconnections, the local power reserve 25 cannot be realized by the primary regulators in sufficient volume. All this causes an undesirable change in the specified mode of operation of power lines and, of course,
учитыва наличие в современных прот женных объединенйых э нергосистемах слабых св зей, часто приводит к потере устойчивости.Taking into account the presence of weak links in modern extended unified energy systems, often leads to loss of stability.
Сохранению заданного потокораспределени способствуют вторичные системы автоматического регулировани частоты и мощности 1 .The preservation of a given flow distribution is facilitated by secondary systems for automatic frequency and power control 1.
Однако эти систе№г сложны, часто имеют невысокое быстродействие и требуют дл своей реализации дорогосто щих телеканалов, в силу чего они устанавливаютс лишь на некоторых агрегатах энергосистемы.However, these systems are complex, often have low speeds and require expensive TV channels for their implementation, which is why they are installed only on some power system units.
Цель изобретени - повышение устойчивости энергосистем.The purpose of the invention is to improve the sustainability of power systems.
