Návrh bypassu parní turbíny pro zvýšení elektrického regulačního rozsahu

Abstract

Diploma thesis deals with proposal of high pressure steam by-pass of steam turbine flow duct. The main aim is to utilize as much as possible steam turbine minimum power design range. It is required for offering supporting services to ČEPS with preservation of steam boiler necessary circulating flow. Steam amount produced by boiler but not consumed by turbine will be led through by-pass station outside the turbine directly to condenser. By-pass station should be able to control required by-pass high pressure steam amount an in the same time to guarantee pressure and temperature decrease of by-passed steam without an adverse limiting of turbo-generator operation or offering supporting services to ČEPS.
