One of the oldest and largest sources of renewable energy, which uses the natural flow of moving water to generate electricity

Hydropower

What are the two types of Hydro powered turbines?

Reaction, Impulse

Height of standing water

Head

Flow of water

Volume

The type of Hydro powered turbine selected for project is based on

Head , Volume

Generates power from the combine forces of pressure and moving water

Reaction turbine

Generally used for sides with lower head and higher flows and arc most common type of currently used in United States

Reaction turbines

Uses the velocity of the water to move the runner and discharges at atmospheric pressure

Impulse turbine

Suitable for high head, low flow applications

Impulse turbine

What are the two main types of impulse turbine?

Pelton, Crossflow

It has a runner with 3 to 6 blades

Propeller turbine

The turbine and generator are a sealed unit placed directly in the water stream

Bulb turbine

The generator is attached directly to the perimeter of the turbine

Straflo

Both the blades and the wicked gates are adjustable slowing for a wider range of operation.

Kaplan turbine

Who invented Kaplan turbine

Victor Kaplan

The first modern Hydro powered turbine And has a runner with fix blade usually nine or more

Francis turbine

Also called as a free flow, turbines generate electricity from the kinetic energy present inflowing water, rather than the potential energy from the head

Kinetic turbine

What are the two types of reaction turbines

Francis, Kinetic

It has one or more free, jets, discharging water into an irritated space and impinging on the buckets of runner

Pelton turbine

It has a one to 100 kW of capacity

Micro Hydro

It has 101 kW to 10 MW

Mini Hydro

It has more than 10 MW of capacity

Large Hydro

Mechanical devices that convert the energy of flowing or falling water into mechanical power

Water, wheels and Watermills

It involves the use of flowing or falling water to generate electricity

Hydro power for electricity

Are devices like our comedian, screws or hydraulic gram can be employed to lift the water from lower levels to higher level levels

Water lifting devices

Involves using the energy of moving water to perform task, like operating gates, controlling the flow of water in canals, or even powering, certain agricultural machinery

Hydraulic power

Can be used to operate irrigation systems. It includes the energy from flowing water to lift in transport water to field for crap irrigation.

Irrigation systems

In remote or upgrade areas small scale Hydro power system can be installed to generate electricity for activities providing sustainable resource

Micro Hydro systems

Give at least six dams in the Philippines

Magat Dam, Pulangi Dam, Agus Power Plant , Kalayaan, Ambuklao Hydroelectric Power Plant, San Roque Dam, La Mesa Watershed and Eco-Park, Pantabangan Dam, Angat

What are the large hydroelectric power plants in the Philippines?

Magat Hydro Power Plant, Angat Hydropower Plant , Agus VI Hydroelectric Plant

Magat

Cagayan Valley, 388 MW

Pulangi Iv

255 MW, Northern Mindanao, Philippines

Agus VI Hydro Powerplant

Marawi City , 200 MW

Angat Dam

208 MW, Bulacan

Pantabangan Dam

Nueva Ecija

La Mesa Watershed and Eco Park

Quezon city

San Roque

San Miguel, Pangasinan

Kalayaan Dam

736 MW, Calabar zone

NPC stands for

National power corporation

NIA

National irrigation administration

Good alternative to provide low-cost electricity to far-flung places that are accessible to continue with supply of water

Micro Hydro

This produces enough electricity for large towns and extensive green supplies. This produces more than 10 MW of power.

Full scale Hydro

Provides power between 3 to 10 MW

Small hydropower

This is a smaller Hydro system than mini Hydro and generally do not contribute to national greed. This is used in remote area where the power grid does not extend.

Micro Hydro

Typically used to supply power for one rural industry or one rural community. It has a power range from 200 W to 300 kW.

Micro Hydro

Tu applications of micro hydros system

Mechanical power, Electrical power generation

It makes use of a dam to stop river flow building, a preserve of water behind the dump

Storage scheme

This does not stop the river flow, but instead divert part of the flow into channel and pipe, and then threw a turbine

Run of the river scheme

What are the components of micro hydros scheme?

Intake and diversion weir, Settling basin, Channel , Forebay tank, Penstock, Powerhouse, Consumer

This is used to divert waters through an opening of the river into an open channel

Intake and diversion weir

This is used to remove sand particles from the water

Settling basin

This follows the contour of the Hillside, serving a canal to convey water

Channel

Used to store water before it enters the penstock

Forebay tank

A pipe that conveys water from the forebay tank to the turbine

Penstock

This is where the power is generated from the turbine to the generator, including its accessories

Powerhouse

Final end of the system, where the power generated is consumed for various applications, such as domestic use of processing operations

Consumer

Efficiency of penstock

90%

Efficiency of civil works

95%

Efficiency of turbine

80%

Efficiency of generator

85%

Efficiency of transformer

96%

Efficiency of transmission

90%
