4、ntion.ivCopyright 2006 IEEE. All rights reserved.IntroductionThis introduction provides some background on the rationale used to develop this guide. This information ismeant to aid in the understanding and usage of this guide. This version of the guide is a revision of theoriginal published in 1992.

5、 The P1147 Working Group reviewed the original guide and revised it by addingnew sections on plant staffing and cold weather. The working group also revised the clause on governors,excitation systems, and transformers to enhance them with the most current experience of the workinggroup. Bibliographi

6、c references were added and the entire guide was reorganized to conform with the formatof the latest IEEE Style Manual. Numerous editorial changes and minor technical improvements were doneto enhance clarity and understanding.This document is a guide for the hydroelectric power industry to assist hy

7、droelectric power plant owners,operators and designers in the economic (feasibility) and technical evaluation (electrical aspects) of existinghydroelectric installations for rehabilitation. Feasibility study results may indicate redevelopment of the site.Redevelopment will not be treated in detail i

8、n this guide.The guide is intended to be used as a reference document for practicing engineers in the hydroelectric powerindustry.Owners of hydroelectric power plants have four options to consider after evaluating the performance andoperation of plants and individual units in the plant. These option

9、s are:a) Retirementb) Continue operation as-isc) Redevelopmentd) RehabilitationThe first two options are self-explanatory. Option c), redevelopment, involves the construction of anessentially new plant by replacement of all or a major part of the plant equipment and structures in order tomake optimu

10、m use of the hydro resource.This guide will address option d), rehabilitation. Rehabilitation should result in extended life, improvedperformance, increased reliability, increased availability, reduced maintenance, and improved operations.This guide covers all generating equipment up to and includin

11、g the main transformer and typical auxiliaryequipment.All aspects of the power plant should be considered for rehabilitation including the typical structural,electrical, and mechanical systems shown in Figure 1. For example, improved performance can be achievedby replacement of the turbine runner wi

12、th a modern design, or by upgrading the generator or improvingauxiliary support systems. Increased reliability, reduced maintenance, and improved operations can beachieved by rehabilitation of appurtenant electrical equipment such as exciters, regulators, governors,transformers, and control systems.

13、 These and related subjects are addressed in this guide.Although this document covers civil, structural, mechanical, and hydraulic aspects of a hydroelectric powerplant, they are not covered in great detail. The intent is to provide sufficient information from these otherdisciplines to assist the re

14、ader of this document in the understanding of how the electrical aspects relate to orare affected by these other features. As an historical note, the initial first drafts of this guide were coordinated with the ASCE Hydro PowerDevelopment Committee and the ASME Hydro-Power Technical. During the late

15、st revision of the guide, itThis introduction is not part of IEEE Std 1147-2005, IEEE Guide for the Rehabilitation of Hydroelectric Power.Copyright 2006 IEEE. All rights reserved.vwas reviewed and commented upon by the ASME Hydropower Technical Committee (HPTC). TheWorking Group would like to thank

16、the HPTC for their time and helpful contributions made to this guide.This guide addresses conventional hydropower. Portions of this guide are relevant to pumped storage, butthe unique features of pumped storage are not covered in the guide.The plant owner should be aware of current safety codes and

17、standards during the plant assessment andrehabilitation.The plant owner should be aware that the rehabilitation of his plant may require the need for amending thelicense with the appropriate regulating agency. The owner should also investigate historical preservation andenvironmental regulations tha

18、t may impact the rehabilitation program.The bibliography is a listing of industry standards, recommended practices, and guides that may be used as aresource by the engineer engaged in power plant rehabilitation. The review of those documents that apply tothe desired area of rehabilitation is encoura

19、ged. The listing may not be the most recent edition but is meantto be an aid in starting the review process. If the referenced publications are superseded by an approvedrevision, the revision shall apply.WATERWAYSHEADWATERTUNNELS AND POWER CANALSSURGECHAMBERINTAKETURBINEGENEXCCBTA ILWATERDRAFT TUBEI
