Introduction

The overall level of large-scale hydropower equipment manufacturing industry continues to increase, stand-alone capacity continues to grow, stand-alone capacity of 1000MW hydroelectric generating units Work has been staged results, the need to organize the development of standards, production for the crew to provide technical preparation.

This Guidance Document is based on the research, summary and summary of the model tests and operation experience of the existing large hydro turbines under construction Basis, according to the relevant current international, national and industry standards or norms for preparation.

The basic principles for the compilation of this technical guidance document are to highlight the characteristics and important concerns of a 1000MW turbine.

Stage in the development phase of the product guidance document.

1000MW Francis turbine Model Acceptance Test Guidelines

1 Scope

This Guidance Document provides for the determination of whether the value of the contractual guarantee for the main hydraulic properties has been met Flow turbine model acceptance test.

This Guidance Document is applicable to the same-station comparison test of 1000MW Francis turbine model under laboratory conditions and model acceptance test.

The 1000MW Francis turbine of this Guidance Document refers to the rated power (or nameplate power) of the turbine rated power (Or nameplate power) for the 862MW ~ 1100MW, and the rated head range of 100m ~ 300m Francis turbine.

As long as the structure or part of the machine does not affect the performance of the model or the relationship between the model and the prototype, Does not involve the detailed structure of the machine, nor the mechanical properties of the machine part.
