    The future of Wind Farms

    As offshore wind farms move towards deploying higher capacity turbines of 5MW

    and above, energy losses during energy transfer will escalate unless higher voltages

    are used for power evacuation.

    In comparison with onshore installations, offshore wind

    farms have more predictable wind flows and avoid conflictswith other types of land use; however higher costs imply

    the necessity to pursue economies generated by increasing

    the power of the turbines and the dimensions of the farms

    on the one side and decreasing the power absorbed by the

    collection grid on the other.

    The increases of the produced power, of the distance from

    shore, of the distance between wind turbines and of theirnumber in a single wind farm have amplified the importance

    of reducing the power losses that may be obtained using HV

    connection.

    EWEA forecasts predict that in the next two decades the traditional 2 MW and 3 MW turbines will nearly completely give way to

    turbines of 5 MW and above, operating in farms producing hundreds of MW each.

    The PASS modular design allows a wide range of

    configurations fully comprehensive of: Circuit breaker;

    Disconnecting switches;

    Earthing switches;

    Current transformers;

    Voltage transformers;

    Surge arresters;

    Protection and control systems.

    PASS M00 is a suitable solution for HV W ind Farm collection

    grids due to its main advantages:

    Compactness due to full gas insulation;

    Short installation time (no HV test is required on site);

    High reliability obtained through lean design; Fast repair in case of faults due to modular assembly;

    Remote control permitted by motor operability;

    Easy combination with oil insulated, gas insulated and dry

    power transformers;

    Easy cable connection by means of plug-in components;

    Long life time due to proven design for harsh environmental

    conditions.

    PASS M00

    PASS M00 is the ABB line of

    multifunctional modules that cover

    voltages between 72.5 kV and 100 kV

    and breaking currents up to 40 kA.

    Reduce the number of array

    necessary to evacuate the energyarising from Wind Turbine generators;

    Reduce the numbers of cables in

    parallel for each feeder due to lower

    currents;

    Enhancing the power capacity

    of each feeder, the number of

    wind turbines for each feeder can

    increase;

    Reduce the losses in subsea AC

    internal grid array cables;

    Decrease the voltage drop in feeders/

    string; Decrease the short circuit value on

    internal grid apparatus;

    Avoid the construction of off-shore

    HV/MV platform substation when

    off-shore wind farms are close to the

    coast;

    Make possible having flexible internal

    configuration and reaching higher

    reliability.

    The advantages of high voltage modules

    A case study of new generation offshore Wind Farms equipped with 5 MW turbines

    revealed that the use of PASS M00 modules in 72 kV collection grids allowed to fit

    a complete HV substation within a tower.

    Example of configuration with TIPThe Inductive power transformer (TIP) combines the

    capabilities of a voltage transformer for voltages

    up to 420 kV with the characteristics of a power

    transformer with ratings up to 200 kVA; therefore it is

    a perfectly suitable solution for supplying the PASS

    M00 switchgear and other auxiliary services, with

    these advantages:

    Reduced dimensions;

    Maintenance free;

    Fast connection; High reliability;

    Wide range of available power;

    Possibility to include a disconnector;

    Resistance to stressful environmental conditions.
