The MiMiC Power Generation Modeling Objects are rigorous first-principles, dynamic models of boiler with furnace, steam header, fuel, and turbine designed for high-performance simulations for operator training or automation system testing.

The MiMiC Power Generation Modeling Objects are part of the MiMiC Advanced Modeling Objects License that adds sophisticated modeling objects into the MiMiC Simulation Studio modeling palette. These objects can be used on MiMiC systems for application software testing or operator training. The MiMiC Advanced Modeling Objects License provides:

• Medium-High to High Fidelity Simulation Performance
• Rigorous First Principles process modeling using proven dynamic, real-time modeling methods
• Unit Operation modeling objects
• Easy handling of individual stream component physical properties using MiMiC Component Sets
• Block to block communications of all parameters with one connection using MiMiC Streams
• MiMiC OTM Process Snapshot support
• MiMiC OPC Server Access to all model parameters

In MiMiC Simulation Studio, process models using these objects can be integrated with any other models or MiMiC dynamic modeling blocks. All modeling blocks in MiMiC are IEC1131 function blocks. Models can be built off-line and then viewed executing on-line with real-time values from the MiMiC Simulation engine. The process of going from off-line model building to on-line model tuning is fast and intuitive.

Power Generation Modeling Objects Overview

The Power Generation Modeling Objects provide high-fidelity dynamic model for a wide range of the power generation facilities configurations. The modeling objects include:

• Fuel Object that can be characterized for gas, oil, coal, wood, or other fuel source. 
• Boiler with Furnace Object providing complete combustion model, water and steam balance model and all associated equipment.
• Steam Header Object for complete mass and energy balance of saturated or superheated steam flows across entire header.
• Pressure Reducing Valve Object for pressure and flow modeling between steam headers.
• Furnace Object providing complete combustion model and heat transfer for up to 8 fuels.
• Turbine Object for complete steam and power generation balance.

Fuel Object

The Fuel Object can be characterized for gas, oil, coal, wood, or other fuel source.  Composition can be characterized for precise combustion modeling in mass or molar basis.  The fuel composition can be specified for carbon, hydrogen, sulfur, nitrogen, and oxygen content, as well as overall heat capacity.

Boiler with Furnace Object

The Boiler with Furnace object provides a complete integrated model of the combustion process and steam / water balance in the power plant boiler.  The modeling basis is proven power generation stoichiometry and first principles mass and energy balances.  Up to five fuel feeds can be configured for each furnace with any combustion source available from the MiMiC Fuel Object.  The combustion model is complete and accurate including flue gas composition, energy generated, full combustion characteristics modeled.  Water/Steam balance model has all components of the boiler including the Steam Flow, Feed Water Flow, and Drum Level.  Boiler equipment is accurately modeled with user selections for each subsection of the boiler including Primary Superheater, Desuperheater, Secondary Superheater, Economizer, Air Heater, and Precipitators.

Steam Header Object

The Steam Header Object is built to handle saturated or superheated steam from up to 8 inlet streams, distributed to up to 8 outlet streams.  Pressure, temperature, and total steam mass of the header are modeled.  A complete, rigorous mass and energy balance is calculated across the entire header each second.

Pressure Reducing Valve Object

The Pressure Reducing Valve Object provides dynamic pressure and flow modeling between steam headers.  Complete configuration settings allow the valve object to be tuned to an exact valve performance characteristic.  Users of Fisher Control Valves, can select the Fisher valve option that allows the user to directly enter the valve characteristic settings from Fisher Controls Severe Service Catalog 10.

Turbine Object

The Turbine Object provides a complete Steam and Power Generation Balance around this equipment including the Steam Inlet Extraction and Exhaustion Balance.  The Turbine object supports all commonly used operation modes and can be run in pressure control, power control, or extraction flow control modes. 

Furnace Object

The Furnace Object provides a complete combustion and heat transfer model for steam generators or process furnaces.   Up to 8 fuels of any type can be configured for each object.  

Proven Power Generation Modeling

The MiMiC Power Generation Modeling Objects have been proven on a wide range of power plant projects including coal boilers, gas/oil boilers, and solid waste incinerators.  It provides high-fidelity, dynamic process modeling suitable for automation system testing or development or operator training.  When combined with the MiMiC Operator Training Manager it is a powerful solution for operator training either before an automation project startup or for operational excellence initiatives.
