What is PD IEC/TR 61850‑90‑10 – Models for scheduling in communication network about?

PD IEC/TR 61850‑90‑10 is an international standard that focuses on communication networks and systems for power utility automation.

PD IEC/TR 61850‑90‑10 is a technical report, that describes the models for scheduling the devices using the IEC 61850 series. It specifies the terms, definitions, requirements for schedules, principles for modelling schedules, IEC 61850 LNs and CDCs, etc.

• Installers and service providers for Communication networks

Why should you use PD IEC/TR 61850‑90‑10 – Models for scheduling in communication networks?

IEC 61850 series defines Communication Networks and Systems for Power Utility Automation, and more specifically the communication architecture for subsystems like substation automation systems. The sum of all subsystems may also result in the description of the communication architecture for the overall power system management.

PD IEC/TR 61850‑90‑10 is applied during specified time periods for scheduling the models or devices in a communication network. It explains to you a schedule consists of a series of entries,  which represent the value of a setpoint, the activation value for a particular mode, or the value of a parameter for a mode.

PD IEC/TR 61850‑90‑10 informs you that the most common use of schedules is for scheduling real power output. In that case, DER systems that directly manage their power output, such as reciprocating engines and energy storage systems, may use schedules to determine the time and level of power output.

PD IEC/TR 61850‑90‑10 covers the following rules apply to determine the active schedule:

• Between schedules in the Running state with different priorities, the schedule with the highest priority is the Active schedule.
• For periodic schedules, a new occurrence is considered as a transition in the Running state
• Schedules for direct values
• Schedules for pricing information.
