PD IEC/TR 61850-90-17:2017

What is PD IEC/TR 61850-90-17 – Methods for transmitting power quality data about?

PD IEC/TR 61850-90-17 is an international standard that focuses on communication networks and systems for power utility automation.

PD IEC/TR 61850-90-17 is a technical report, that provides a way of exchanging power quality data between instruments whose functions include measuring, recording and possibly monitoring power quality phenomena in power supply systems, and clients using them in a way that is compliant with the concepts of IEC 61850.

PD IEC/TR 61850-90-17 provides:

• Guidelines for using IEC 61850 for power quality domain
• Name space extensions based on power quality function assessment
• Profile for using IEC 61850 in the specific context of IEC 61000-4-30

Note 1: The measurement of PQ phenomena may be provided by communication e.g. IEC 1850-9-2 or instrument transformers. Their application is outside of the scope of PD IEC/TR 61850-90-17.

Note 2: PD IEC/TR 61850-90-17 provides recommendations for naming conventions for PQ measurements provided by power quality instruments to manifest the usage of Power quality measurement methods and to ensure interoperability.

Who is PD IEC/TR 61850-90-17 – Methods for transmitting power quality data for?

PD IEC/TR 61850-90-17 on models for transmitting power quality data is useful for:

• Electrical and electronics engineers
• Mass media/ telecommunication industry
• Telecommunication engineers and technicians
• Installers and service providers for Communication networks

Why should you use PD IEC/TR 61850-90-17 – Methods for transmitting power quality data?

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 61850-90-17 is an informative technical report that presents you to power quality measurement instruments, used to evaluate the quality of electricity (voltage characteristics) supplied by distribution and transmission systems and to evaluate the performance (emission) of equipment.

PD IEC/TR 61850-90-17 provides you with the services and data modeling for the transmission of PQ-related data from instruments to substation/SCADA systems.

PD IEC/TR 61850-90-17 informs different types of data for different applications of PQ data:

• Power quality monitoring:
• Continuity of supply monitoring
• Monitoring of different voltage characteristics: Voltage quality (VQ) covers a wide range of voltage disturbances and deviations in voltage magnitude or waveform from the optimum values.
• Power quality compliance reporting:
• Continuous monitoring and compliance reporting of different voltage characteristics at the point of connection.
