Claims (8)

1. Способ регулирования мощности паросиловой установки с турбоагрегатом, содержащим паровую турбину и генератор, при эксплуатации которой производят впрыскивание воды в поверхность нагрева перегревателя или перед ней, отличающийся тем, что настройку избыточной мощности генератора порядка 3 - 5% в расчете на полную нагрузку предпринимают в течение времени реакции порядка до 30 с путем повышения расхода впрыскиваемой воды.1. The method of regulating the power of a steam-powered installation with a turbine unit containing a steam turbine and a generator, during the operation of which water is injected into the heating surface of the superheater or in front of it, characterized in that the excess power of the generator is set to about 3 - 5% per full load in the reaction time is up to 30 s by increasing the flow rate of the injected water. 2. Способ по п. 1, отличающийся тем, что для настройки избыточной мощности генератора повышают расход впрыскиваемой воды в перегреватель высокого давления или перед ним. 2.
