摘要： The embodiments described herein include a system and a method. In a first embodiment, a system includes a controller configured to control power plant operations. The system further includes a heat recovery steam generator (HRSG) monitor communicatively coupled to the controller and configured to receive inputs corresponding to the power plant operations. The system additionally includes an HRSG life prediction model configured to predict an operating life for an HRSG component. The HRSG monitor uses the HRSG life prediction model and the inputs to communicate a control action to the controller.

摘要： A combined cycle power plant includes a gas turbomachine, a steam turbomachine operatively coupled to the gas turbomachine, and a heat recovery steam generator operatively coupled to the gas turbomachine and the steam turbomachine. The heat recovery steam generator includes a high pressure reheat section provided with at least one high pressure superheater and at least one reheater. The combined cycle power plant further includes a controller operatively connected to the gas turbomachine, the steam turbomachine and the heat recovery steam generator. The controller is selectively activated to initiate a flow of steam through the heat recovery steam generator following shutdown of the gas turbomachine to lower a temperature of at least one of the high pressure superheater and the at least one reheater and reduce development of condensate quench effects during HRSG purge of a combined cycle power plant shutdown.
