recordPQ_Characteristics_WW1
Extends from Generic_PQ_Characteristics (record for generic PQ characteristics (empty)).
Information
1. Purpose of model
record for generic PQ characteristics of a black coal steam unit based on 'Wedel Block 1 (WW1)'
2. Level of detail, physical effects considered, and physical insight
(Purely technical component without physical modeling.)
3. Limits of validity
(Purely technical component without physical modeling.)
4.Interfaces
(no remarks)
5. Nomenclature
(no elements)
6. Governing Equations
(no equations)
7. Remarks for Usage
All records (PQ diagrams and Heat input matrixes) included in this package are included with the intention of illustrating the modelling concept.
However, users are encouraged to create their own records based on the plants and scenarios that they want to simulate.
8. Validation
(no validation or testing necessary)

Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Real[:,3] | PQboundaries (from Generic_PQ_Characteristics) | Limits of electric power for given thermal power output | |
| Real[:,:] | PQ_HeatInput_Matrix (from Generic_PQ_Characteristics) | Heat input demand for given thermal and electric power setpoint | |
| Real | k_Q_flow (from Generic_PQ_Characteristics) | 1 | Allows to scale Q_flow (= 1/Q_flow_n for generic pq diagrams) |
| Real | k_P_el (from Generic_PQ_Characteristics) | 1 | Allows to scale P_el (= P_el_n for use of generic pq diagrams) |
| Modelica.Units.SI.HeatFlowRate | Q_nom_condenser (from Generic_PQ_Characteristics) | max(PQboundaries[:, 1]) | define condenser nominal power separately without scaling PQ-characteristics |
| Modelica.Units.SI.Efficiency | eta_total_best (from Generic_PQ_Characteristics) | 1 | Total efficiency in the best operating point |
