Scope This standard applies to electric power systems in stationary generating stations that provide electric power to the power
12、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 pr
13、eceding power systems and does not include nomenclature for instrumentation, controls, or auxiliaries. 2. Purpose The purpose of this standard is to provide nomenclature for the specic description of generating station electric power systems and the system components. The use of this nomenclature in
14、 industry standards and other documents is intended to reduce ambiguity and provide universal interpretation. The abbreviations and abridgment provide a means of conserving space. 3. Definitions 3.1 General In general, denitions of words and terms are found in IEEE Std 100-1972, IEEE Standard Dictio
15、nary of Electrical and Electronic Terms (ANSI C42.100-1972 ); Abbreviations for Use on Drawings and in Text (ANSI Y1.1-1972 ), and ANSI C84.1-1970, Voltage Ratings for Electric Power Systems and Equipment. Some of the following denitions have been developed because the reference sources have omitted
16、 them or because their current usage in the power engineering science indicates a required clarication. 2 Copyright 1977 IEEE All Rights Reserved IEEE Std 505-1977IEEE STANDARD NOMENCLATURE FOR GENERATING 3.2 Definitions alternative (electric power system): A qualifying word identifying a power circ
17、uit, equipment, device, or component available to be connected (or switched) into the circuit to perform a function when the preferred component has failed or is inoperative. See also reserve. auxiliaries (collective): For more than one auxiliary, that is, auxiliaries bus, auxiliaries power transfor
18、mer, etc. auxiliary: Any item not directly a part of a specic component or system but required for its functional operation. control center: An assembly of devices for the purpose of switching and protecting a number of load circuits. The control center may contain transformers, contactors, circuit
19、breakers, protective and other devices intended primarily for energizing and deenergizing load circuits. electric components: The electric equipment, assemblies, and conductors that together form the electric power systems. functional nomenclature: Words or terms which dene the purpose, equipment, o

21、s. normal: See preferred. power system: The electric power sources, conductors, and equipment required to supply electric power. preferred (electric power system): That equipment and system conguration selected to supply the power system loads under normal conditions. rectier: A device for convertin
22、g ac to dc. reserve (electric power system): A qualifying term used to identify equipment and capability that is available and is in excess of that required for the load. NOTE The reserve may be connected to the system and partially loaded or may be made available by closing switches, contactors, or
23、 circuit breakers. Reserve not in operation and requiring switching is sometimes called standby equipment. standby: See alternative and reserve. station auxiliary (generating station): Any auxiliary at a generating station not assigned to a specic unit. station service transformer: A transformer tha

Nomenclature Selection Criteria 4.1 General The nomenclature selected to be standard permits the identication of generating station electri
28、c power system components. The standard identication is the standard word or words for each component and the modiers that identify its function. 4.2 Definitions The nomenclature selected has denitions found in standard dictionaries which are appropriate to electric power supply systems. Only the mo
29、st frequently used meaning of a word applies. Synonyms, acronyms, slang, and ambiguous words and terms are excluded. When a specic denition is intended it is included in this standard. 4.3 Components and Functions Standard words and terms are limited to generating station electric power system compo
30、nents and their functions. 4.4 Descriptive Prefixes Words and terms that describe the type and kind of component are excluded. 4.5 Abbreviations The abbreviations indicated are unique for the purposes of this standard. 5.
