10.1 Activity calendar
Activity calendar is time of use (TOU) object for tariff control. It allows modeling and handling
of various tariff structures in the meter (energy and demand rate control).
It is a definition of scheduled actions inside the meter, which follow the classical way of
calendar based schedules by defining seasons, weeks and days.
After a power failure, only the “last action” missed from “Activity calendar” is executed
(delayed). This is to ensure proper tariff after power up.
Activity calendar consists of 2 calendars, active and passive, and an attribute for activation of
passive calendar. Changes can be made only to the passive calendar and then
activated to become active calendar. Each calendar has following attributes:
• Calendar name,
• Season profile (up to 12 season)
• Week profile table (up to 12 week types)
• Day profile table (up to 12 day profiles)
10.2 Special day table
The special day object is used for defining dates with special tariff programs. According to
COSEM object model special days are grouped in one object of COSEM class “special
days”. Each entry in special days object contains the date on which the special day is used.
The “Day_id” is the reference to one day definition in day profile table of the activity calendar
object. In the meter one activity calendar object and one special days object are imple-
mented. With these objects all the tariff rules (for energy and demand) must be defined.
Date definition in special days object can be:
• Fixed dates (occur only once),
• Periodic dates.
Special days object implementation in meter allows to sets 64 special day dates.
10.3 Register activation
With this object registers it is determined which values should be recorded and stored. The
selection of registers depends on meter type and configuration. Attribute 2 of this object
shows which registers are available in the meter to register. Each register has its own index
number and this index is used to identify the register which should be selected. There is a
separate energy and maximum demand object where data to register can be set. Energy or
demand objects can therefore be set separately with 16 different masks.
The complete set consists of
• 12 energy types (A+, A-, /+A/+/-A/, /+A/-/-A/, R+, R-, R1, ... R4, +S, -S … ), 8 tariff
registers each
• 7 demand types (+P, -P, /+P/+/-P/, +Q, -Q, +S, -S), 4 tariff registers each.
