What is PD IEC/TR 61850-1 - Communication networks and systems for power utility automation about?
PD IEC/TR 61850 is a series on communication networks and systems for power utility automation. Communication networks are a group of nodes interconnected by telecommunication links that are used to exchange messages between the nodes. PD IEC/TR 61850-1 is applicable to power utility automation systems (PUAS). PD IEC/TR 61850-1 defines the communication between intelligent electronic devices (IEDs) in such a system and the related system requirements. PD IEC/TR 61850-1 gives an introduction and overview of the IEC 61850 standard series. PD IEC/TR 61850-1 refers to and might include text and figures coming from other parts of the IEC 61850 standard series.

PD IEC/TR 61850-1 on communication networks and systems for power utility automation is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use PD IEC/TR 61850-1 - Communication networks and systems for power utility?
The possibility to build Power Utility Automation Systems rests on the strong technological development of large-scale integrated circuits, leading to the present availability of advanced, fast, and powerful microprocessors. The result was an evolution of substation secondary equipment, from electro-mechanical devices to digital devices. This in turn provided the possibility of implementing a Power Utility Automation System using several intelligent electronic devices (IEDs) to perform the required functions (protection, local and remote monitoring, and control, etc.). As a consequence, the need arose for efficient communication among the IEDs, especially for a standard protocol. Initially specific proprietary communication protocols developed by each manufacturer were used, requiring complicated and costly protocol converters when using IEDs from different vendors.
PD IEC/TR 61850-1 introduces the power utility automation systems standardization which is used to develop a communication method that will meet functional and performance requirements while supporting future technological developments. To be truly beneficial, a consensus must be found between IED manufacturers and users on the way such devices can freely exchange information. PD IEC/TR 61850-1 aims to ensure that the complete communication profile is based on existing IEC/IEEE/ISO/OSI communication standards if available, that the protocols used will be open and will support self-descriptive devices. it should be possible to add new functionality, that the standard is based on data objects related to the needs of the electric power industry, that the communication syntax and semantics are based on the use of common data objects related to the power system, that the communication services can be mapped to different state-of-the-art protocols, that the communication standard considers the implications of the substation being one node in the power grid, i.e. of the power utility automation system being one element in the overall power control system, that the complete topology of an electrical system (single line diagram), the generated and consumed information, and the information flow between all IEDs are specified, using a machine-readable language. Using PD IEC/TR 61850-1 you can specify power utility automation systems.
