    System description 13 System description What this chapter contains This chapter describes the main components of a wind turbine and describes the functionality of the wind turbine converter as a part of a complete wind turbine system. General Variable-speed wind turbine concepts can be divided in two main categories, wind turbine systems equipped with a doubly-fed asynchronous generator or wind turbine systems equipped with an induction generator like squirrel-cage-, synchronous- or permanent magnet synchronous generator.

  • Page 14: Acs800-67

    Yaw motors ACS800-67  ACS800-67 is air-cooled four-quadrant wind turbine converter for wind turbine applications. The converter can be located up in the nacelle or in down tower of the wind turbine. The converter allows independent control of real and reactive flow in either direction (grid to rotor), or confined to unidirectional (rotor to grid) real power flow.

Ability to convert mechanical energy into electrical energy (or vice versa) is based on electromagnetic induction.

  • Page 21: Control Of Torque And Reactive Power Via Rotor-Side Converter

    System description 21 Control of torque and reactive power via rotor-side converter With DTC technology field orientation is achieved by using advanced generator theory to calculate the accurate generator torque. The performance of DTC controlled wind turbine converter is most effective and benefits are eg, fast torque response, accurate control also at low frequencies, torque repeatability and accuracy of dynamic and static speed operations.
  • Page 22 22 System description The basic DTC block selects the inverter switch states so that tangential motion of the flux vector is controlled by the torque error and the radial motion of the flux is controlled by the flux error. The torque reference is supplied by the WTC. The torque feedback is calculated by using stator-side quantities (at grid frequencies) ie, by a cross product of stator flux and stator current.
  • Page 23 System description 23 The rotor-side flux reference is chosen to achieve the desired power factor at the stator terminals. The operating flux level of the stator flux is completely dependent on the grid voltage and therefore the rotor flux reference is dependent on actual stator flux. The figure below shows the vector diagram of stator voltage, current and flux and rotor flux at leading and lagging power factors when the stator is regenerating to the electrical power network.

  • Page 25: Control Of Torque And Reactive Power Via Grid-Side Converter

    System description 25 Control of torque and reactive power via grid-side converter The fundamental theory of grid-side converter can be simplified to be analog to the synchronous generator. One voltage source is the electrical power network and the other voltage source is the grid-side converter. The voltages and currents can be presented as vectors.
  • Page 26 26 System description Reactive power is transferred only if there is an amplitude difference between the two voltage vectors. Reactive power transfer equation is following: For the desirable magnitude and direction of the power and reactive power flow, the length of the converter voltage vector and its phase angle (with respect to the grid voltage vector) must be controlled.

  • Page 27: Overview Of Converter Interfaces

    Overview of converter interfaces The WTC controls the converter using its main control word. For more information, refer to section ABB Drives communication profile on page 90. The start-up procedure of the converter is recommended to be proceeded with the DriveWindow PC tool.

  • Page 28: Converter Control

    28 System description Converter control General  The WTC operates as the overriding controller of the converter. It is connected to the NDCU control unit of the rotor-side converter via fieldbus. The rotor-side converter control program controls the rotor-side power modules according to the references and commands sent by the overriding controller.

  • Page 29: Fieldbus Control

    Fieldbus control of the grid-side converter is performed via the rotor-side converter NDCU control unit. The principle of reference and actual value chains in the control are shown in the diagram below. For details, see ACS800-67(LC) doubly-fed induction generator control program firmware manual [3AUA0000071689 (English)].

  • Page 30: Grid Codes

    30 System description Grid codes Grid codes specify static and dynamic requirements to be fulfilled by a wind power installation. Static requirements mainly determine the voltage control and power control during normal operation. Most of the recent grid codes include also power quality requirements such as harmonics distortion limits, flicker etc.

  • Page 31: Example Limit Curves

    System description 31 Example limit curves According to this example, electrical power network failure (eg, voltage dip/sag) may not cause instability above the limit line 1 or disconnection of the converter from the grid. The limit curves for voltage at the grid connection in case of a fault in the grid are shown below. U denotes the remaining grid voltage and U the converter nominal voltage.

  • Page 32: Grid Fault Ride-Trough Capability

    32 System description Grid fault ride-trough capability Although the advantage of doubly-fed concept is that the size of the wind turbine converter is significantly smaller than full-power converter, the drawback is that the rotor-side converter is a vulnerable part of the system. It has a restricted overcurrent limit and it needs special attention especially during faults in the grid.
  • Page 33 System description 33 Optional MCB3 MCB1 DC chopper ABRU (optional) MCB2 ACBU CONVERTER CTRL WIND TURBINE CTRL With the crowbar and the DC chopper, the wind turbine is capable of handling fault situations like rotor overspeed, short interruptions, voltage dips/sags and swells. With these energy absorbers, the converter is capable of meeting even the most strictest grid fault ride-through requirements in accordance with international grid codes.
