Vertical 600kw Mini Water Turbine Generator For Micro Hydro Power Plant

overview

A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity. The operation of a generator is based on the principles discovered by Faraday. He found that when a magnet is moved past a conductor, it causes electricity to flow. In a large generator, electromagnets are made by circulating direct current through loops of wire wound around stacks of magnetic steel laminations. These are called field poles, and are mounted on the perimeter of the rotor. The rotor is attached to the turbine shaft, and rotates at a fixed speed. When the rotor turns, it causes the field poles (the electromagnets) to move past the conductors mounted in the stator. This, in turn, causes electricity to flow and a voltage to develop at the generator output terminals."

1. Nozzle and Flow Regulating Arrangement (Spear)

Nozzle is used to increase the kinetic energy of the water that is going to strike the buckets or vanes attached to the runner.

the quantity of water that strikes the buckets is controlled by spear. The spear is installed inside the nozzle and regulates the flow of water that is going to strike on the vanes of the runner. A nozzle containing spear is shown in the figure given below.

the spear is a conical needle present in the nozzle. It is operated by a hand wheel or automatically in an axial direction.

when the spear is move backward the rate of flow of water increases and when it is pushed forward the rate of flow of water decreases.

2. Runner and Buckets

The runner with buckets is shown in the figure given below.

Runner is a rotating part of the turbine. It is a circular disc on the periphery of which a number of buckets evenly spaced are fixed.

The buckets are made by two hemispherical bowl joined together. Each buckets have a wall in between two hemispherical bowl called splitter.

The splitter splits the jet of water striking the buckets into two equal parts and the jet of water comes out at the outer edge of the bucket.

The buckets are designed in such a way that the jet of water strike the buckets, deflected through 160 degree to 170 degree.

The buckets of the Pelton turbine are made up of cast iron, cast steel bronze or stainless steel.

3. Casing:

The outer covering of the this turbine is called casing. The Pelton turbine with the casing is shown in the figure given below.

4. Breaking jet

When the jet of water is completely closed by pushing the spear in forward direction than the amount of water striking the runner becomes zero. But still the runner keeps moving due to the inertia of the runner.
