Information

Overview

This is model is the decision maker in the CHP model. According to different conditions and timings it decides if the CHP can be turned on or off.

Concept

The following control decisions are implemented:

• Switch On when the flow temperature is lower than a setpoint.
• Switch Off when the CHP should work in a range lower than its minimum allowable capacity.
• Allow the CHP to be switched On only if it was Off for more than a certain amount of time (delay) or it was On beforehand.
• Allow the CHP to be switched Off only if it was On for more than a certain amount of time (delay) or it was Off beforehand.
• Emergency measures such as maximum allowable flow and return temperatures are implemented.
