.TransiEnt.Consumer.Gas.Control.NCVController

Information

1. Purpose of model

Model to control mass flow rate by measured net calorific value and given enthalpy flow rate input.

2. Level of detail, physical effects considered, and physical insight

If usePIDcontroller, a LimPID controller will be used. The limits are set according to the mode (Producer, Consumer, both).

If not usePIDcontroller, the mass flow rate is calculated.

3. Limits of validity

(no remarks)

4. Interfaces

m_flow_is - Current hydrogen mass flow in kg/s

NCV_is_sink - actual net calorific value in sink in J/kg

NCV_is_source - actual net calorific value in source in J/kg

m_flow_desired - desired mass flow in kg/s

H_flow_set - Desired thermal power in W

10. Version History

Model created by Lisa Andresen (andresen@tuhh.de) in May 2016

Model modified by Robert Flesch (flesch@xrg-simulation.de), Nov 2020: added NCV in different flow directions
