Abstract
Hydropower Project in the layout of the plant downstream of the dam on the side of the ground (usually close to the dam) of the hydropower station called Bahou-hydropower station,. Bahou-river hydropower station suitable for slower slope, a dam built the conditions of the river. The main advantage of this power station is the dam and the plant into its own building system, a relatively simple structure, the construction of the plant and dam interfere with each other less. Because the plant near the dam, located in this way can the diversion dam, power generation shorten the length of pipe. Bahou-hydropower station in Bashang You have greater capacity to regulate the flow of water reservoirs, to increase the installed capacity of power plants, electric power system to adapt to the peak load regulation requirements, the use of water than the full, comprehensive utilization of the benefits of high , And often can not only play a role in flood control, Hennessy also meet other requirements. Bahou-hydropower plant electrical design is part of the main transformer and the choice of the main electrical wiring diagram of the design. Will be mentioned in the design load analysis, the short-circuit, and lightning protection equipment, such as the choice of the design and calculation. This is normal operation of hydropower stations and ensure that people working and living conditions of the necessary electricity. The design was entitled "Bahou-hydropower station electrical part of the design." Design of the main elements include: load analysis and computation; installed capacity of the hydropower station; main electric wiring and design; short-circuit current calculation of the programme of economic analysis, the choice of electrical equipment; relay equipment; mine and ground protection and so on.
