IEC 61850-90-10 Draft Technical Report on Schedules just published

IEC TC 57 just published the Draft Technical Report:
IEC/TR 61850-90-10 Ed.1.0 (57/1762/DTR)
Communication networks and systems for power utility automation -
Part 90-10: IEC 61850 objects for scheduling

Closing date for voting is 2016-09-30

Schedules establish which behavior (e.g., tariff 1 or 2, mode 1 or 3) or expectation (e.g., forecast) is applied during specified time periods. A schedule consists of a series of entries with a setting for the value of a setpoint, the selection of a particular mode or the value of a parameter for a mode.
There are different ways to operate a scheduled entity based on the following operation principles:

  • The actual values of a scheduled entity (e.g. active and reactive power produced or consumed) are directly controlled using setpoints and controls. For example, the DER system reacts on changes of the setpoints or on controls (e.g. start or stop the DER system) in real time.
  • The functional behavior of a scheduled entity is configured to operate in a mode in which it responds to locally sensed conditions (e.g. Volt-VAr Mode in case of DER) or externally provided information (e.g. prices). 

The schedules offer a very powerful functionality that can be used in many different applications.
Currently we have two major applications in Germany  that make use of the schedules: 
  1. VHPready
  2. FNN Steuerbox
NettedAutomation has implemented the most crucial concepts on an embedded controller used in the HMS gateways.

More to come soon.
