IEEE 1615-2007 pdf free.IEEE Recommended Practice for Network Communication in Electric Power Substations.
This document defines a recommended practice for communication and interoperation of devices connected on an electric power substation Internet protocol (IP) network. It does not establish a new underlying communications standard. Instead, the document prescribes a specific set of existing conventions and definitions.
1.2 Purpose
This recommended practice provides direction for implernenters who wish to produce interoperable communications equipment for an electric power substation network. It also provides criteria for users, system integrators. and equipment manufacturers who need to establish requirements for the transfer of operational and non-operational data as well as configuration management.
2. Normative references
The following referenced documents are indispensable for the application of this document (i.e., they must be understood and used, so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments or corrigenda) applies.

4. Electric utility information system architecture
An electric utility information system is defined for this recommended practice as a set of interrelated applications, data acquisition/control equipment, and communication channels designed to provide specific functions for the utility. Frequently, the overall information system is designed and controlled as separate subsystems, each with its own set of components. Examples include supervisory control and data acquisition (SCADA), energy/distribution management systems (EMS/DM S), protective relaying, equipment monitoring, power quality evaluation, and system planning and design. Regardless of the specific functions being performed or the level of integration between components, all of these subsystems can be viewed similarly with respect to the communication architecture. Each has data that needs to be transported. and equipment that needs to be configured and monitored. The data must also be processed.
An electric utility information system is an “overlay” technology in that its sole purpose is to improve thc operation of another system—namely, the electric power system. The usefulness of the information system is always expressed in terms of the amount of efficiency that can be gained in the operation of this other system.
The usefulness of any information system depends on three factors (see Figure 1):
a) What information is available and how can it be used (data)
b) The timeliness of delivery and ability to react to changes (speed)
c) The maintenance and overhead required for upkeep and expansion (maintenance).IEEE 1615 pdf download.
