Cascade (menu structure 2.6.3.)
The cascade function makes it possible to operate several Hoval CHP plants in parallel
and highly economically with the aim that only one CHP plant is in the modulation range
when the heat demand decreases. The remaining CHP plants are either in standby mode
or in full load mode. Consequently, it is possible to reduce the modulation range to as low
as 5 kWh.
In order to obtain a balanced number of operating hours for all cascaded CHP plants,
the power curves are automatically reassigned between them on a regular basis (6-hour
intervals). This means that the maintenance technician can service all CHP plants at the
same time after the service interval has expired, and the maintenance costs are reduced.
The prerequisite is that each CHP plant control unit is connected to the router or switch
via a LAN cable, so that communication between CHP plants can be guaranteed.
The respective CHP plants must also be marked either as "Master" or as "Slave".
The cascade function allows several installed Hoval CHPs to be operated economically in
parallel. The aim is to operate a maximum of only one CHP plant in the modulation range.
The remaining CHP plants should either be in standby mode or run at full load.
In order to obtain a balanced number of operating hours between all CHPs, the power
curves are regularly reallocated between them. This means that the maintenance
technician can service all CHP plants at the same time after the service interval has
expired.
Each individual control unit must be connected to a router or switch via a LAN cable and
declared as either a "Master" or a "Slave".
When the "Cascade" button is pressed, the following window appears. When the cascade
function is activated, the cascaded CHP plants communicate with each other.
