Известны способы защиты пгфсгазовой установки от разрыва труб иоверхностск нагрева парогенератора путем отключени установки по косвенному параметру 1. Така защита ИГУ, а именно зашита от понижени перепада давлений на циркул ционном насосе, может остановить установку при разрыве труб испарительного контура, так как в этом случае иерепад на циркул ционном насосе падает.There are known methods for protecting the gas compressor unit from breaking pipes and the surface heating of a steam generator by turning off the installation using an indirect parameter 1. Such protection of the IGU, namely, protection against lower pressure drops at the circulation pump, can stop the installation if the evaporating circuit pipes break, since in this case ipad on the circulation pump falls.
Однако скорость падени перепада, завис ща от величины разрыва, .может не снизитьс до аварийного значени . При разрыве труб пароперегревател эта защита BOOOUIC не действует , что снижает надежность зашиты парогазовой установки.However, the rate of drop of a differential, depending on the magnitude of the discontinuity, may not decrease to an emergency value. If the superheater pipes break, this BOOOUIC protection does not work, which reduces the reliability of the combined-cycle installation.

Это достигаетс тем, что в качестве косвенного параметра используют из ;еиение соотношени между расходом воздуха lia парогснеракоторых i;ocTvnaioT в устройство 4, где оии сравниваютс ,This is achieved by using, as an indirect parameter, the ratio between the air flow rate lia of steam engines for which i; ocTvnaioT to device 4, where they are compared,
