Guide for Installation of Vertical Generators and Generator/Motors for Hydroelectric Applications
|Publication Date:||1 January 1989|
(This Foreword is not part of IEEE Std 1095, IEEE Guide for Installation of Vertical Generators and Generator/Motors for Hydroelectric Applications.)
Large hydraulic turbine-driven generators are shipped as components and completely assembled and installed at the site. The installation, therefore, becomes a continuation of the manufacturing process, and many of the operations involved are those that are normally performed in the factory on smaller generators. Close tolerances must be maintained in the fit and alignment of the various parts. The use of proper installation procedures is essential to achieve satisfactory operation of the unit.
This Guide incorporates much of the information previously found in the National Electrical Manufacturers Association (NEMA) publication MG 5.2, Installation of Vertical Hydraulic-Turbine-Dr
In 1985 the Energy Development and Power Generation Committee of the IEEE Power Engineering Society agreed to sponsor the Guide, and the Hydroelectric Power Subcommittee undertook the task of reviewing, revising, and reissuing it.
The IEEE Std 1095 , IEEE Guide for Installation of Vertical Generators and Generator/Motors for Hydroelectric Applications Working Group wishes to acknowledge the contributions made to the guide by R. D. Handel and J. M. Quigley.
The procedures for installation, described in this Guide, apply to all types of synchronous generators and generator/ motors rated 5000 kVA and above to be coupled to hydraulic turbines or hydraulic pump/turbines having vertical shafts. All references made in this Guide to "generators" apply equally to "generator/motors."
