Associated causal chains

This component is part ofInstallation causal chains— from cause to effect (gas quality → engine → exhaust gas → heat → efficiency). The AI reads the entire chain, not just the individual value.

Link with the entire installation

A CHP unit is never alone: electricity, heat and gas are linked, and with PV and battery storage, it becomes a system. The AI calculates the entire installation.

Frequently Asked Questions

What is the function of a grid protection relay in the CHP?
It protects the CHP and the public grid against damage caused by faults such as short circuits or overloads at the connection point.
Why is active power monitoring important?
Monitoring ensures that the generator set (CHP) injects constant power in accordance with the agreed power (e.g. 901kW) and that no control deviations occur.
From when must a grid protection relay be maintained?
Regular checking of switching times and measured values is mandatory in accordance with the current grid operation rules for injection.
How does the relay detect an error in the CHP?
It measures parameters such as current, voltage and frequency and triggers within a few milliseconds if defined limits are exceeded.
What happens in case of a malfunction of the grid protection relay?
The relay disconnects the installation from the grid to prevent a chain reaction or damage to the injection equipment.
What role does the Baseline play during CHP operation?
The Baseline serves as a reference value for normal operation, in order to immediately identify deviations in active power and in the behavior of the grid.
