WY Field Trip - Wind Farm - Glossary

 
glossary
base power - the amount of power necessary to meet minimum demands of customers. A base load power station is usually available 24 hrs a day, 7 days a week and operates at full power most of the time. 6 ways of providing base load power from wind.
blade blade


- the winglike part of the turbine. Most turbines have 2 or 3 blades.
electricity - a flow of charged particles, which may be electrons or ions. It is measured in watts or kilowatts
energy - the strength to move or do something. We get our energy from food. Plants get energy from sunshine. Cars get their energy from fuel: gasoline, or plants, or batteries. In this website we are talking about the wind providing the energy to make electricity.
generation - the conversion of other forms of energy, such as the wind, into electrical energy through special equipment. Check out this animation of a wind turbine generator
grid - an interconnected power transmission network that delivers electricity from the power source to your house, and other customers. It includes a power source, high voltage transmission lines, power pole, transformers,and lines to your house. http://www.windpower.org/en/tour/grid/index.htm
kWh -an unit of energy equal to one kW applied for one hour. One unit of electricity is 1kWh (one kilowatt-hour), "kilo" means thousand, so one kilowatt-hour is the amount of electricity used by an 1000W appliance running for 1 hour.
load - the moment-to-moment measurement of power consumption of the entire system
- also force and weight that a structure is designed to withstand.
nacelle nacellekbsm


- the box behind the blades, holding the equipment that turns the wind motion into electricity
non-renewable energy -an energy resource that can not be replaced once it is used up. Examples include fossil fuels such as oil,coal, and natural gas.
power - the ability to perform work or produce a change to a condition. Power is a flow rate of energy, or a rate of use of energy. We can't store electric power, but we can store electrical energy.
renewable energy - an energy resource that will not run out. Examples are sun, wind, wave, biomass, and geothermal.
rotor - the blades and the hub of a wind turbine

- a tall structure that supports a wind generator
transmission - the transportation of energy along a network or grid of power lines
turbine - machine for generating rotary mechanical power from the energy of a moving force (such as wind, water, or steam). Turbines spin 2 or 3 blades connected to a rotor that turns a generator to make electricity. Photo
watt - a unit for measuring electricity
wind - the movement of air caused by the uneven heating of the earth's surface by the sun.
wind rose - a drawing that shows the information about the distributions of wind speeds, and the frequency of the varying wind directions. See an example from the Danish Wind Industry Association.

- a group of wind turbines used to generate electricity.
