Nauru communication base station wind power short circuit

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.

With the support of development partners, including Australia, Japan, and the USA, this project will bring reliable, high-capacity broadband to Nauru, benefitting over 100,000 people across the region. NFCC was established to manage the cable's implementation in Nauru.

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.

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.

Worldwide thousands of base stations provide relaying mobile phone signals. Every off-grid base station has a diesel generator up to 4 kW to provide electricity for the electronic equipment involved. The presentation will give attention to the requirements on using windenergy as an energy source for powering mobile phone base stations.

The PFCC is set to give the generator unity power factor at rated power output. Figure 3-14: Network used for simulation of a Type I wind turbine generator with power factor correction capacitor and unit step-up transformer. Table 3-3: Generator Step-up Transformer Parameters.
