What is PD IEC/TR 61850-90-2 – Power utility automation about?
PD IEC/TR 61850-90-2 is an international standard and a part of the PD IEC/TR 61850 series that discusses communication between substations and control centres for power utility automation. An integrated Distribution Automation system enables Indian power utilities to have real-time control over the costly energy sold.
PD IEC/TR 61850-90-2 provides a comprehensive overview of the different aspects that need to be considered while using IEC 61850 for information exchange between substations and control or maintenance centres or other system-level applications. In particular, this technical report:
- Defines use cases and communication requirements that require an information exchange between substations and control or maintenance centres
- Describes the usage of the configuration language of IEC 61850-6
- Gives guidelines for the selection of communication services and architectures compatible with IEC 61850
- Describes the engineering workflow
- Introduces the use of a Proxy/Gateway concept
- Describes the links regarding the Specific Communication Service Mapping (SCSM)
Who is PD IEC/TR 61850-90-2 – Power utility automation for?
PD IEC/TR 61850-90-2 on communication networks and systems for power utility automation applies to:
- Manufacturer of power grids
- Electrical engineers
Why should you use PD IEC/TR 61850-90-2 – Power utility automation?
A control centre is a place where a master station (SCADA, EMS, DMS, GMS, grid operator) receives and processes data coming from substations. A substation is a system consisting of a place where high voltage devices (circuit breaker, isolator, transformers) related to an electrical grid, facilities necessary for system security, control and communication (Proxy/Gateway, IED) are located.
PD IEC/TR 61850-90-2 provides communication between the substation and the control centre in which the requirements are the same as inside the substation for the connection between the bay station and station level. The binary rules and analogue values are been exchanged depending on the functions applied. Differences are the longer communication distance and the transparent use of an external communication system with higher or lower bandwidth, which increases the transmission delay.
As a user of PD IEC/TR 61850-90-2, you can be ensured of the communication between substations and control centres for power utility automation.
