Combined Cycle: Normal Operations

Identify and describe the major components of a combined cycle power plant. Describe how control system components and operating set points are often adjusted to enable operators to achieve normal operating conditions in a combined cycle power plant. Identify and describe preliminary checks that are typically performed prior to a combined cycle plant startup. Describe the procedures involved in starting up the combustion turbine the heat recovery steam generator (HRSG) and the steam turbine in a combined cycle power plant. Describe the procedures involved in shutting down the HRSG the steam turbine and the combustion turbine in a combined cycle power plant. Describe how a DCS is used to monitor and control the plant during normal operation to maximize efficiency. Describe how a DCS is used to perform routine operational checks and maintenance during normal operation.
