Abstract
The paper discusses general considerations and future possibilities for the design of generating equipment for tidal power plants with particular reference to Bay of Fundy sites. Factors affecting the design of turbines, generators, excitation system, powerhouse layout and the main electrical connections are reviewed. Various alternatives for transmission of power to shore are listed and the choice of SF6 gas insulated bus duct is substantiated by comparative data. Advantages of integrating the high-voltage switching station with the powerhouse, using SF6 gas insulated metal-clad switchgear are discussed. Application of computers and microprocessors is envisaged. The paper concludes that advances in technology can make a significant contribution to economic development of tidal power.
