Динамическая устойчивость газотурбинной электростанции комбинированного цикла на Алчевском металлургическом комбинате

Abstract

Object of research is power station with steam-gas cycle, which uses as fuel gas for a gas-turbine unit gases of metallurgy production. Subject of research is transient stability of power station of 2x151.5 MW, which gives out its power in electric network of 110 kV. For normative disturbances (3 phase short circuit, with breakdown of circuit breaker) stability of gas-turbine station generators is maintained (in some cases – after short asynchronous motion), synchronous stability of generators of Donbass electric power system is maintained for all case.
