    NM72/82 Arctic Specification

    PAGE 3/6

    1 Arctic specification turbines

    For use in areas with extremely low temperatures, the Arctic specification for NM72/82 has been

    developed.

    The limitations are to operate at temperatures down to

    ÷

    30

    °

    C AT (Ambient Temperature) and structural

    endurance down to

    ÷

    40

    °

    C at stand still.

    In general, all steel, welds, casts and cables are specified to meet above requirements. Further, all

    components, lubrication and hydraulic oil are selected to meet the cold conditions keeping required

    properties.

    Some components are specifically selected to replace normal equipment, and special heating systems are

    added. The following is a description of the items where the arctic version of the NM72/82 Arctic

    differs from the standard version.

    2 Strategy for operating in cold weather conditions

    During normal operations the gearbox and generator will generate heat within the closed nacelle

    compartment, and secure suitable temperature conditions for all components.

    Sensors monitor the ambient temperature, as well as all relevant component and system temperatures,

    and shut the turbine down if operational limits are exceeded.

    After a stand still, where components have become very cold, nacelle-heating equipment will ensure

    heating up before resuming normal operation.

    There are two purposes for this: first to ensure that the lubricants have optimal properties and secondly

    to heat up the nacelle including gearbox, generator, main bearing and yaw mechanism.

    Operation will not commence until specified components have obtained their minimum temperature

    acceptance level. The wind turbine computer continuously checks the temperature level.

    During operation the nacelle heating equipment will automatically be turned on and off, to secure

    acceptable operation temperature inside the compartment.

    3 Arctic equipment and component specific details

    3.1 Nacelle heating

    In order to heat the nacelle, 2 fan heaters are installed in the nacelle. They have a capacity of 20 kW

    each. The fan heaters are mounted primarily to warm up the yaw mechanism and the main gear.

    Secondarily, they heat all other components in the nacelle.

    The heating units are controlled by the wind turbine computer on basis of temperature sensors, which

    are placed in the nacelle compartment, gear oil and bearings, cooling liquid, and the bearings of

    generator, rotor shaft and yaw system.

    3.2 Gearbox

    Cartridge heaters are installed in the gearbox, in order to heat the oil, when starting up at low

    temperatures. The gearbox is equipped with 3 heaters at a capacity of 0.8 kW each.

    The sequence of heating up the oil in the gearbox is:

    1.

    Cartridge heaters and the nacelle heaters will heat up the oil from  ̃ °C to � °C

    2.

    When the oil reaches -20°C the turbine will be allowed to idle with at max speed of 250 RPM.

    The idling operation is an effective way of heating up the gear box oil.

    3.

    When the oil temperature reaches ±0 °C the tu rbine is allowed to generate max. 400 kW of

    power.

    4.

    When the oil temperature reaches +10 °C the turbine is released for normal operation.

    The procedure is shown in the graph below.

    3.3 Cooling system

    The NM72/82 cooling system is designed to operate in temperature ranges from  ̃°C to +40°C

    This system is standard for all NM72/82s.

    3.4 Meteorological equipment

    The arctic specification turbine will, as a standard, have:

    One Ultra sonic FT702LT combined wind vane and anemometer

    One NRG IceFreeII Wind Direction Vane

    One NRG IceFreeII Heated anemometer

    The ultra sonic instrument has three heating elements and an “intelligent” deicing control.

    Parameters for the control of the heating element can be set by the user.

    The heaters draw up to 6A in extreme conditions.

    The picture below shows the ultra sonic instrument, mounted next to standard wind vanes and

    anemometers in an icing situation.

    The NGR instruments have a simple internal heater that maintains the instrument at 140°C by means of

    a PTC resistance element.

    3.5 Rotor

    The pitch hydraulic system uses oil with low index of viscosity suitable for operation at -30°C. The

    accumulators mounted in the hub are equipped with heating mats to ensure proper viscosity of the oil.

    There are 9 heating mats at a capacity of 0.2 kW each. Furthermore, the grease on the bearings is

    different from standard due to the viscosity.

    As a standard, blades are suitable for operation at  ̃°C.

    3.6 Controller

    The controller is, as a standard, mounted with heaters as follows: 2 x 0.35 kW in the power panel, 2 x

    0.35 kW in the control panel, 2 x 0.35 kW in the power factor correction panel and 1 x 0.35 kW in the

    top box. There are no additional heaters mounted in the controller at the arctic version.

    Thermal sensors in the cabinets control the heating elements, which are turned on if the temperature

    falls below the preset minimum limit. The heaters will secure adequate temperatures for running the

    wind turbine computer.

    3.7 Structural parts

    All structural parts, e. g. tower, mainframe, hub, bolts and blades are, as a standard, suitable for

    operation at  ̃°C and surviv

    al to at least  °C.

    Power Factor Correction

    

    

    [Description: Drawing of a turbine cut-in.]

    

    

    •

    The full load compensation system maintains unity Power Factor after turbine cut in using a 5 step capacitor bank.

    

    

    •

    The TAC II controller continuously measures the actual reactive compensation needed. The system then maintains specified Power Factor by switching in or out a combination of capacitor steps that meet the required reactive compensation.

    

    

    •

    The TAC II controller can switch steps in any order, but each step requires a 2 minute discharge delay before being activated again.
