Wind Compact Substation FAQ
-
What is a Wind Compact Substation?
A Wind Compact Substation is an integrated power distribution unit designed for wind farms, combining transformers, switchgear, and control systems in a single enclosure for efficient energy transmission.
-
What voltage levels does it support?
It typically supports medium voltage (e.g., 11kV, 33kV) to low voltage (e.g., 400V, 690V) conversion, matching wind turbine and grid requirements.
-
Is it suitable for harsh environments?
Yes, it is built to withstand extreme weather, high humidity, salt spray, and temperature fluctuations common in wind farm locations.
-
What cooling methods are used?
Depending on the design, it may use natural air cooling, forced ventilation, or liquid cooling to maintain optimal operating temperatures.
-
Does it include protection features?
Yes, it integrates overcurrent, short-circuit, earth fault, and surge protection to ensure safe and reliable operation.
-
Can it be customized for different wind turbine capacities?
Yes, compact substations can be tailored to match specific turbine power ratings, typically ranging from 1.5MW to 6MW or higher.
-
How is maintenance performed?
Designed for minimal maintenance, it includes accessible compartments and remote monitoring options to reduce downtime.
-
What certifications does it comply with?
Common certifications include IEC, IEEE, and local grid codes, ensuring compliance with international safety and performance standards.
-
What is the expected lifespan?
With proper maintenance, a Wind Compact Substation can operate reliably for 20-25 years.
-
How does it support grid connection?
It steps up turbine-generated voltage to grid-compatible levels and may include reactive power compensation (SVG/SVC) for grid stability.
