OMICRON CMC 356

Purpose: To ensure all transmission and generation Protection Systems affecting the reliability of the Bulk Electric System (BES) are maintained and tested.   Applicability Transmission Owner. Generator Owner. Distribution Provider that owns a transmission Protection System. Effective Date: In those jurisdictions where regulatory approval is required, all requirements become effective upon approval. In those jurisdictions where no regulatory approval is required, all requirements become effective upon Board of Trustee’s adoption or as otherwise made effective pursuant to the laws applicable to such ERO governmental authorities.   Requirements 1. Each Transmission Owner and any Distribution Provider that owns a transmission Protection System and each Generator Owner that owns a generation or generator interconnection Facility Protection System shall have a Protection System maintenance and testing program for Protection Systems that affect the reliability of the BES. The program shall include: Maintenance and testing intervals and their basis. Summary of maintenance and testing procedures. 2. Each Transmission Owner and any Distribution Provider that owns a transmission Protection System and each Generator Owner that owns a generation or generator interconnection Facility Protection System shall provide documentation of its Protection System maintenance and testing program and the implementation of that program to its Regional Entity on request (within 30 calendar days). The documentation of the program implementation shall include:   Evidence Protection System devices were maintained and tested within the defined intervals. Date each Protection System device was last tested/maintained.   Measures 1. Each Transmission Owner and any Distribution Provider that owns a transmission Protection System and each Generator Owner that owns a generation or generator interconnection Facility Protection System that

The IEC 61850 standard defines the communication between intelligent electronic devices in the substation and the related system requirements. The abstract data models laid out in IEC 61850 can be mapped to a number of protocols which include MMS (Manufacturing Message Specification), GOOSE, SMV (Sampled Measured Values), and soon to Web Services. The protocols can ran over TCP/IP networks or substation LANs using high speed switched Ethernet to obtain the necessary response times below four milliseconds for protective relaying. To date, the IEC 61850 standard is divided into 10 parts which are the following: 1) IEC 61850-1 - Part 1: Introduction and overview - Gives an introduction and overview of the IEC 61850 standard series; refers to and includes text and figures from other parts of the IEC 61850 series. 2) IEC 61850-2 - Part 2: Glossary - Contains the glossary of specific terms and definitions used in the context of Substation Automation Systems which are standardized in the various parts of the IEC 61850 series. 3) IEC 61850-3 - Part 3: General requirements - Applies to substation automation systems and more specifically defines the communication between intelligent electronic devices in the substation and the related system requirements. 4) IEC 61850-4 - Part 4: System and project management - Describes the requirements of the system and project management process and of special supporting tools for engineering and testing. 5) IEC 61850-5 - Part 5: Communication requirements for functions and device models - Applies to substation automation systems and standardizes the communication between intelligent electronic devices and the related system requirements. Refers to the communication requirements of the functions being performed in the substation automation system and to device models. 6) IEC 61850-6 - Communication networks and systems for power utility automation - Part 6: Configuration description language for communication in
