Electrical Connections in Power Systems and Wind Farms

These flashcards cover essential terms and definitions related to electrical connections, transmission systems, and wind farm operations as presented in the lecture notes.

Electrical connections

Vital for power systems, enabling electricity transfer from generation sources to end users.

High Voltage Transmission

Transmission of electricity at higher voltages (275kV and 400kV) through overhead lines and underground cables.

Substations

Facilities that convert electricity into different voltages for distribution.

Distributed Generation

Small-scale power generation technologies, such as wind and solar, connected to the grid.

Maximum Power Point Tracking (MPPT)

A technique used to maximize power capture from wind turbines with minimal losses.

Reactive Power Control

Management of reactive power to support voltage levels on the electricity grid.

HVAC (High Voltage Alternating Current)

A transmission system commonly used for electrical power across long distances.

HVDC (High Voltage Direct Current)

A more efficient power transmission system for long distances, particularly offshore wind farms.

Skin Effect

The tendency of alternating current to flow mostly near the surface of conductors, increasing effective resistance.

Offshore Wind Farms

Wind generation facilities located in water, benefiting from higher wind speeds and less turbulence.

Power Losses

Energy losses that occur during electricity transmission, influenced by distance and voltage levels.

Electrical Connection Topologies

Various configurations for connecting turbines and substations within a wind farm for optimal efficiency.

Transformer

A device used to step up or step down voltage levels in electrical systems.
