Foreword

This instructional document has been drafted in accordance with the rules given in GB/T 1.1-2009.

This guidance document is proposed by China Electrical Equipment Industry Association.

This Guidance Document is organized by the National Committee for Standardization of Hydraulic Turbines (SAC/TC175).

The main drafting of the technical guidance of the unit. Harbin Electric Works Co., Ltd., Dongfang Electric Group Dongfang Electric Co., Ltd., China Academy of Water Conservancy and Hydropower Research, China Three Gorges Corporation, China East Construction Engineering Research Institute Co., Ltd., Yangtze River Survey Planning Design Co., Ltd.

Introduction

The overall level of large-scale hydropower equipment manufacturing industry continues to improve, stand-alone capacity continues to grow, stand-alone capacity of one million kilowatts of hydroelectric units for the staged achievements, it is necessary to organize the development of standards and provide technical preparation for the commissioning of units.

This guiding technical document is based on the project of Wudongde and Baihetan Hydropower Station and is based on the research results of the following two research projects.

1) National Science and Technology Support Project "Research on Key Technologies of 1000MW Hydropower Units"; 2) China Three Gorges Corporation Project "One Million the overall design of hydroelectric generating units, turbine hydraulic design and model tests. " this guidance document is based on the construction, of large-scale hydro-generator set design, manufacture, operating experience to study, sum up and total Based on the conclusion, according to the relevant current international, national and industry standards or norms for preparation.

The basic principles for the preparation of this technical guidance document are to highlight the characteristics and important concerns of a million-kilowatt hydroelectric generating unit.

The basic requirements and the current standards have repeated content, is the stage of innovative products in the development phase of the guidance document.
