Introduction

Since the installation of the 700MW hydroelectric generating set of the Three Gorges Project in China, the installation of a domestic giant hydroelectric generating set has entered a Peak, Longtan, Xiaowan, Laxiwa, Xiluodu, Xiangjiaba power plant giant units have been put into operation, the installation of the giant unit of more attention to the quality of the total Results giant unit installation quality testing standards is imperative, the original GB GB/T 8564-2003 quality testing standards need to be improved, with After improving the quality inspection standards can also guide Baihetan, Wudongde and other follow-up giant unit installation.

This guidance document is based on the summary of the domestic large hydro-generator sets (single-flow capacity of 700MW and above Francis turbine Motor unit) installed on the basis of quality standards prepared for the future stand-alone capacity 1000MW Francis turbine installation Quality testing provide a standard basis.
