IEEE C37.1-1994 pdf free.IEEE Standard Definition, Specification and Analysis of Systems Used for Supervisory Control, Data Acquisition, and Automatic Control.
Abstract: Distributed multi-computer master stations and distributed remote terminal units (RTUs) are introduced. Submaster RTUs used in an automated distribution system with downstream feeder RTUs is defined. Local area networks with master stations are discussed. Intelligent electronic devices (IEDs) with respect to their interface to RTUs and master stations are defined. New surge withstand capability (SWC) standards and their applicability to SCADA is shown. An example channel loading calculation is provided.
Keywords: automatic control, data acquisition, SCADA, supervisory control.
IEEE C37.1 applies to systems used for monitoring, switching, and controlling electric apparatus in unattended or attended substations, generating stations, and power utilization and conversion facilities. It does not apply to equipment designed for the automatic protection of power system apparatus or for switching of communication circuits. The requirements of this standard are in addition to those contained in standards relating to the individual devices (e.g., switchgear).
This is a significant revision of IEEE Std C37. I – 1987 . This revision reflects current technology that is generally being provided to meet the requirements of utilities today. Originally, this standard was a section of ANSI C37.2- 1970, which also contained device function numbers. ANSI C37.2-1970 was revised into two standards: IEEE Sid C37.l- 1979 , Standard Definition. Specification, and Analysis of Manual, Automatic, and Supervisory Station Control and Data Acquisition. and IEEE Std C37.2-1979 , Electrical Power System Device Function Numbers. Previous editions were approved by the IEEE Standards Institute in 1962, 1956, 1945, and 1937. The original work on this subject was done by the American Institute of Electrical Engineers (now the Institute of Electrical and Electronics Engineers) and published in 1928 as AJEE No 26. The latest revision of the standard on Electrical Power System Device Function Numbers is IEEE Std C37.2-1991.
This standard applies to a rapidly changing technology. It is anticipated that frequent revision may he desirable. This revision, prepared by the Electric Network Control Systems Standards Working Group of the Data Acquisition, Processing, and Control Systems Subcommittee of the IEEE Substations Committee, is an attempt to bring the standard up to date and further broaden its applicability with respect to control, supervisory, and telemetering. for greater use in many industries.
IEEE C37.1 applies to. and provides the basis for, the definition, specification, performance analysis, and application of systems used for supervisory control; data acquisition or automatic control, or both, in attended or unattended electric substations, including those associated with generating stations; and power utilization and conversion facilities. Systems covered by this standard typically use processors in the master station and in the remote stations. Such processors provide facilities for incorporating automatic control functions, either by the supplier or by the user, after the system is installed.
This standard does not apply to electromechanical or static, protective-relaying equipment (see IEEE Std C37.90-1989 , IEEE Std C37.90.l-1989 , IEEE Std C37.90.2-1987 , IEEE Std C37.91-1985 , IEEE Std C37.93-1987,
IEEE Std C37.95-1989, IEEE Std C37.96-1988 ,and IEEE Std C37.97-l979 ).
