6 FAQs about [Base station wind power supply short circuit]

How is a wind turbine based on a short-circuit analysis program?

The WTG’s real and reactive current contributions are determined from the defined function and set into a source representing the wind turbine in the system model. The short-circuit analysis program is assumed to be able to model a source of defined current contribution.

What is the short-circuit contribution of a wind plant?

Because a wind plant may have any number of its wind turbines operating at a given time, the short-circuit contribution varies from zero (with no wind turbines in operation) to the maximum current with all turbines operating and in the crowbar condition for a close-in transmission fault.

How accurate is a wind turbine short-circuit model?

In this context, highly accurate short-circuit modeling may be quite difficult to achieve with the only practical alternative a compromise between accuracy and complexity of the wind turbine model. For short circuit studies, Type IV WTGs act as a controlled current source, with current limited to protect the converter electronic devices.

How does a short-circuit analysis program work?

The short-circuit analysis program is assumed to be able to model a source of defined current contribution. If it does not, then the source voltage or impedance must be iterated to achieve the specified current. Once the specified current is obtained, the resulting updated voltage at the MV terminal is determined.

How many wind turbines are connected to a collector substation?

This wind plant has 117 – 1.8 MW Type II wind turbine generator connected to two collector substations. Collector substation A has six 34.5 kV collector lines connecting 78 of the total 117 wind turbine generators. The remaining 39 WTGs are connected to collector substation B via three collector lines.

What are the protection system options for wind plant interconnection?

Several protection system options exist for the wind plant interconnection, the collector system and the transmission system. The protection philosophies are discussed as they pertain to the system design and configuration.
