A modeling system for a plant system of a power plant is provided. The modeling system enables receiving a selection of one or more pre-engineered sub-modules for a plant system module, wherein each pre-engineered sub-module is configured to be scalable over a defined range both for an entire class product range and each potential power plant configuration, and each pre-engineered sub-module is parametrized within the defined range with a pre-defined parametric relationship. The modeling system enables receiving values for one or more variables for the defined range for the one or more pre-engineered sub-modules. The modeling system enables generating a pre-engineered and parametrized sub-module model for each of the one or more pre-engineered sub-modules based on the values for the variables and generating a plant system module model from the pre-engineered and parametrized sub-module models by assembling the pre-engineered and parametrized sub-module models together according to pre-defined rules.

System and method for modeling plant systems utilizing scalable and repeatable modules

A piping layout for a water steam cycle (WSC) system of a combined cycle power plant is disclosed. The piping layout includes a first steam flow pipe delivering steam from a steam source to a high pressure (HP) segment of the ST system. The first flow pipe includes a first vertically oriented thermal expansion portion. The WSC system may also include a second steam flow pipe delivering steam from the steam source to an intermediate pressure (IP) segment of the ST system. It may also include a third steam flow pipe delivering steam from HP segment of the ST system to a steam source. The vertically oriented thermal expansion portion(s) may be positioned immediately upstream of the admission valve of the respective segment and/or immediately downstream from an outlet of the steam source.

A condenser system for steam turbine systems having different loads is disclosed. The condenser system includes a selectively sized outer casing having a variably sized heat exchanger end and an input end for coupling to a steam turbine (ST) system. A condensate vessel sidewall of the casing is positionally uniform relative to the ends regardless of the size of the heat exchanger, and a cooling water sidewall has a position dependent on heat exchanger size.

Condenser system, and condensate vessel assembly for power plant

Modular cooling water assemblies for combined cycle power plant systems are disclosed. Each of the assemblies may include a pump and a heat exchanger, both positioned on a support structure. Additionally, each of the assemblies may include a closed cooling water system supported by the support structure. The closed cooling water system may include a return header fluidly coupled to a return conduit for receiving cooling water previously utilized by the combined cycle power plant system. The closed cooling water system may also include a supply header positioned adjacent the return header, and fluidly coupled to a supply conduit for supplying the cooling water to the combined cycle power plant system. Additionally, the closed cooling water system may include a closed cooling water circuit fluidly coupling the return header to the supply header. The closed cooling water circuit may be fluidly coupled to the heat exchanger and the pump.
