Modification of Two Power Units of the First Stage of the Sochi TPP by Introducing Steam Cross-Connections

  • Published:
Power Technology and Engineering Aims and scope

The retrofitting of two single-boiler-single-turbine units of the first stage of the Sochi TPP by adding cross-connections between them is considered. These cross-connections made it possible to reduce the minimum safe electrical output of these power units by shutting down one gas turbine and keeping both steam turbines in operation. The principal features of the retrofitting are shown. The effect of retrofitting is analyzed at the stage of testing and in a year of operation.
