Introduction

Hydropower construction in China's energy development has an important strategic position, plays an important role in the national economy. With the market for power generation the requirements for the development of high capacity, high parameters, high efficiency and low consumption, safety and environmental protection are continually increasing, and the requirements of the state in the "12th Five-Year Plan" Indeed proposed to vigorously develop hydropower, China will have a group of 1000MW super-large hydropower unit design and manufacture. To this end has prepared the following series Standard. "1000MW-class hydro-generator", for hydro-generator, there are GB/T 7894 "hydro-generator basic technical conditions" GB/T 8564 "Technical Specifications for Installation of Hydro-generating Sets", GB/T 1029 "Three-phase synchronous motor test methods" and related manufacturing, testing, etc.

Aspects of standards and norms. When the single generator capacity increases to 1000MW, the operating conditions of hydropower units, performance parameters, overall Structural and material applications will change. Due to the size of the unit, operating conditions, performance parameters have undergone major changes, these are current of the hydropower unit national design, manufacture, installation, inspection standards will not be fully applicable. Therefore, based on the existing standards and norms, 1000MW-class generators related to the special characteristics of the corresponding research, and developed for the 1000MW-class hydropower unit design, system Made, installed, inspection standards and specifications.

This guidance document is based on the research results and summary of the 1000MW giant vertical hydro-generator in recent years 700MW large-scale vertical hydro-generator design, manufacture, installation, inspection, operating experience compiled, is 1000MW-class hydro-generator Guidance documents related to technical work.
