2.4 Mechanical and electrical design of the Three Gorges Project

Abstract

This chapter talks about the mechanical and electrical design of the Yangtze River Three Gorges Project (TGP) for flood control, power generation and navigation. The main buildings of the Three Gorges Project include the dam, the powerhouse and navigation facilities. The electrical design of TGP mainly deals with the integration of the hydroelectric power station into the power system, main single diagram, single diagram of the station service power supply, inlet and outgoing line mode, selection of high-voltage switchgear, general layout of the project, selection of main electric equipment, over voltage protection, earthing engineering and service illumination. Modern advanced techniques of automation and communication are used to outfit the combined automation system with advanced technology, clear structures and a reasonable management. A topological network diagram of the computer supervision and control system of the Three Gorges-Gezhouba cascade dispatch is provided. Functions of the system, system structure, main technical characteristics of the system and communication of the computer supervisory control system are described. Finally, the chapter discusses the communication system for the Three Gorges-Gezhouba cascade project and electric drive and control of the double-line continuous 5-level ship lock. A short tabular survey of the investment cost of the TGP is also presented.
