GA/T 2930.52—2000
This standard is formulated according to the International T Committee version F6C0G32:93 generation, distribution and power generation, of which the definition of "wind power station" is formulated according to IEC6CC59 (415:19998 small weak turbine motor system, and the terminology of water turbine is formulated according to /T2053.25—1S6 technology for hydraulic turbines, hydraulic systems and pump turbines. The technical content is equivalent to the standard IE30 n50 (602): 9B3 is formulated by the TFC/TCI Electrical Terminology Committee. It is one of the five standards in the series of technical standards for power generation, de-energization and distribution. According to the dynamics of 1FC/TC1T in 2011, EC60C50502): 1083 is effective: This standard is related to the following current electrical standards. In the process of making it, the following standards were proposed and implemented. GB/2!U0.45-13 Electrical. 1. Terminology of water turbine, water curtain and water to water Turbine 3GB/300(.46-1383 Electrical Engineering Code Steam Turbine Reactor and Its Accessories GR/T200048-18A Electrical Engineering Code Fixed Exhaust Furnace 2Gk/T2900.5G-1998 Electrical Engineering Code Generator, Reinforced Electricity and Self-contained Electricity 1 Terminology 3 When the terms and definitions in the national standards differ from [EC: 5005U(602), this standard adopts IEC6(005) (031. However, when the relevant national standards are used, the terms and definitions in this standard are different from those in [EC: 5005U(602). When a new international standard is formulated and the technical content is correct, the relevant national standards will be coordinated. In order to explain the coordination relationship between some terms in this standard and related technical standards, this standard lists the names of these terms in the relevant current national standards and the article numbers after the definitions of these terms. If a term is amended by this standard, the "change" before the long note will be deleted.
Appendix A and Appendix B of this standard are prompt appendices. This standard is issued by the Ministry of Industry and Information Technology.
This standard is issued at the meeting of the Ministry of Industry and Information Technology of the Ministry of Industry and Information Technology. The responsible units for the revision of this standard are: China Electrotechnical Research Institute, China Electrotechnical Research Institute. This standard is a formal resolution of the United States electrical and electronic industry on technical issues, and is formulated by a number of national technical committees with particular interest in these issues. It is intended to provide an internationally accepted standard for these issues. 2) They are used in the form of recommendations and are approved by the national committees. 3) In order to promote international unification, the IEC expresses the wish that the texts of the recommendations be used in the national regulations of each country under the circumstances of their respective agreements. Any differences between the recommended texts and the corresponding national regulations should be pointed out in their national regulations. This publication is one of five in a series of terminology standards for the transmission and distribution of electric power. The series is divided into the following sections: 601 - General terminology 602 - Power generation system terms and management terms 604 - Operating terms 605 - Substation terms This section is a 2004 edition of 1EV25 (second edition) published in 1965. Starting from 1976, the secretariat of the working group was initially assumed by the former Soviet Union State Committee, but after 1976, the German pressure committee was responsible for the "power generation terms" contained in Chapter 62. The "power generation terms" contained in the book are intended to control the limited amount of the book. The technical requirements of power generation equipment are considered on a necessary basis, and only a few terms that are convenient for system designers and operators are selected. Therefore, Chapter 60 is still used as a core technical section, and the terminology of the equipment structure is not included as much as possible. If it is not a necessary document, the Secretariat of TC1/WG01 will be forwarded to the national committees for comments. After the TC1/WG01 working group held a meeting from 1981 to 1983, the first draft was submitted to the National Committee for approval in accordance with the law in June 1981. The following national committees voted to publish the cost of the cost. Purchase, involving Australia
