Teesside cogeneration project and Dowty digital protection scheme

This paper is in two halves: a general overview of the Teesside Project followed by a description of the Dowty protection system between the generating units and the two gas installed substations. The Teesside Power Station is by far the largest independent power station in the UK. It comprises an 1875 MW combined-cycle gas turbine cogeneration plant (CCGT) and has the giant ICI Wilton site as a steam host. The authors describe the main features of the plant, the balance of the plant, process control and staffing. The authors then describe the Dowty pilot wire interface and digital channel protection scheme
