THREE GORGES DAM IN CHINA

5. Critical spare list

Be it any product or a construction, spare parts are obvious for each one of them and this is because everything in this world gets depreciated overtime and there emerges the requirement of spare parts. There are some major parts installed in the three gorges dam in china which are very critical as they play an important role in holding the stout structure strong enough to withstand all foreign turbulence (Liu et al., 2019). Here is a list of the critical spares that are important for the maintenance as well as repair of the dam:

• Dam

This is the primary component of hydroelectric plant at a certain location where the river height matches with the possibility of attaining sufficient energy from water.

• Water Reservoir

This is placed at the back of the dam where the water is stored and the height of the water

decides the amount of potential energy that it may produce.

• Control Gates

These are the gates that are being built at the inside of the dam and are termed as inlet gates.

• Penstock

This is the long pipe that is responsible for carrying water from the reservoir towards power generation unit which is comprised of turbine and generator. Here kinetic as well as potential energy is generated depending upon the height of the reservoir.

• Water turbines

Power generation unit involves turbine which helps in the production of potential energy along with the motion of the blades. In most of the hydroelectric power plants more than one power generation unit is involved (Tian et al., 2019).

• Generators

This is the location where energy is produced and the shaft rotates inside the generator producing alternate current inside the coils. This rotation produces magnetic field that produces electricity through induction. So turbine shaft produces electricity with the help of kinetic and potential energy of water.

• Construction management

Advancement and the leading group of the projecting June 1993, the Three Gorges Project Construction Committee17 embraced the project’s preliminary arrangement report, legitimately dispatching the primer period of the undertaking. The approved adventure included in a multipurpose dam (arranged to flood control, power generation and course), to be constructed multiple stages starting in 1994 and finishing in 2013.

• Flood control

Flood control in the middle and lower scopes of the Yangtze River is the fundamental anyway also determinant reason fought for the Chinese experts to continue with the Three Gorges Dam construction.

• Power generation

Power generation is definitively the resulting reason battled to build up the Three Gorges Dam. Although power smoothly came up short concerning demand from mid 1970s, the money related reforms introduced from late 1970s and the following skyrocket of public economy declined this situation. In the middle 1980s, power inadequacies compelled fabricating plants to work at 70-80% capacity, and power blackouts ended up being essential in metropolitan zones.

• Navigation

The third basic motivation driving the Three Gorges Dam is improving the Yangtze River’s navigation, the Chinese ‘Magnificent Waterway’. Its safeness has made the Yangtze River to be a key smoothly course of correspondence interfacing east, focal and west China since old functions.

8. Budget

The three gorges hydroelectric power project is one of the chinas massive water control facility and its cost in terms of building is within the budget as stated by officials and they even told that the funds have been utilized in a very proper way. The project originated in the year 1993, and construction has been done over the middle reaches of Yangtze river, the most unruly among china. The plant was designed to tame the same as well as enhance the economy of china with the introduction of decent and cost effective energy. The main working of the project is inclusive of dam, among which 26 are located on the banks of the river among which all had gone into operation by the end of last year with a total capacity of installation 18.2 million kw. Supply of hydropower got initiated by the end of june which sold 318.8 billion kwh of energy that is clear enough to state power grids supplying to the east, central and southern parts of the country. In terms of construction many population has been relocated and arrangements that are being made to resettle them comes within the budget only (Luo et al., 2017).
