124.Under what circumstances, the boiler master output will hunt and what is the solution?

Boiler Master demand (PV:Bolier outlet pressure) will hunt when the Load demand controlled by turbine is varying (eg: excessivegrid  frequency variation). In such circumstances, it is better to switch to "Turbine Follow Mode". Boiler controls will look at Load Variation and Turbine controls will maintain Boiler outlet pressure.
