IEEE 505-1977

This standard applies to electric power systems in stationary generating stations that provide electric power to the power system. Nomenclature is included for the following interrelated systems: 1) Generating unit power system 2) Generating unit auxiliaries power system 3) Station auxiliaries power system 4) Generating unit dc auxiliaries power system 5) Station dc auxiliaries power system This standard is limited to the preceding power systems and does not include nomenclature for instrumentation, controls, or auxiliaries.

The purpose of this standard is to provide nomenclature for the specific description of generating station electric power systems and the system components. The use of this nomenclature in industry standards and other documents is intended to reduce ambiguity and provide universal interpretation. The abbreviations and abridgment provide a means of conserving space.

New IEEE Standard - Inactive-Withdrawn. Electric power systems in stationary generating stations that provide electric power to the power system are covered. Nomenclature is included for the following interrelated systems: generating unit power system, generating unit auxiliaries power system, station auxiliaries power system, generating unit dc auxiliaries power system, and station dc auxiliaries power system. Nomenclature for instrumentation, controls, or auxiliaries is not included.
