Complete Analysis of Doubly Fed Induction Generator Wind Turbine

If you don’t know this value, you can leave [0 90]. When External is selected, a Simulink input named Vref appears on the block, allowing you to control akhmztov reference voltage from an external signal in pu. Combined generator and turbine inertia constant H in seconds, combined alhmatov friction factor F in pu based on the generator rating and number of pole pairs p. Default is [ 0. Grid voltage regulator gains [Kp Ki] This parameter is not visible when the Mode parameter is set to Var regulation.

From zero speed to speed of point A, the reference power is zero. When the wind turbine experiences high wind speed, the mechanical vladilav of the wind turbine may be damaged, and hence having a cut-out speed is a safety consideration. Pitch angle controller gain [Kp] This parameter is not visible when the External turbine Tm mechanical torque input parameter is selected. The maximum value of this current is limited to a value defined by the converter maximum power at nominal voltage. So, there is various problem arises while using the wind farm.

Problem Statement 1 Develop a simulation model of wind farm. Since, wind speed is not constant throughout the day. This parameter is not visible when the Mode parameter is set to Var regulation. This page has been translated by MathWorks. An inner current regulation loop consisting of a current regulator. The other one is the generator which transforms the rotational mechanical power to electrical power.

This parameter is not visible when the External turbine Tm mechanical torque input parameter is selected. The voltage or the reactive power at grid terminals is controlled by the reactive current flowing in the converter C rotor.

Select the China site in Chinese or English for best site performance. Maximum rate of change of pitch angle This parameter is not visible when the External turbine Tm mechanical torque input parameter is selected. Converters Tab Converter maximum power The maximum power of both C grid and C rotor in pu of the nominal power. The power control is explained below.

The nominal turbine mechanical output power in watts. Initially, the pitch angle of the turbine blades is zero degree and the turbine operating point follows the red curve of the turbine power characteristics upto point D. Beyond point D the pitch angle is proportional to the speed deviation from point D speed. This parameter is not visible when the Mode parameter is set to Voltage regulation. Between point B and point C the tracking characteristic is the locus of the maximum power of the turbine generatoors of akhkatov turbine power versus turbine speed curves.

As long as the reactive current stays within the maximum current values -Imax, Imax imposed by the converter rating, the voltage is regulated at the reference voltage Vref. Gains of jnduction var regulator.

All Examples Functions Blocks. Preeti Jain2 1 Research Scholar, M. Select Voltage regulation default or Var regulation. This external torque must be in pu based on the nominal electric power and synchronous speed.

The following curve shown in fig.

Introduction to Wind Power. The power at point D is one per unit 1 pu and the speed of the point D must be greater than the speed of point C. Direct-axis and quadrature-axis component of stator current in pu based on the generator rating.

The stator resistance Rs and leakage inductance Lls in pu based on the generator rating. Tracking characteristic speeds This parameter is not visible when the External turbine Tm mechanical torque input parameter is selected.

Grid-Side Converter Control System. An example of such a characteristic is illustrated by the ABCD curve superimposed to the mechanical power characteristics of the turbine obtained at different wind speeds. The frequency of this voltage is equal to the product of the grid frequency and the absolute value of the slip.

The system will reach steady-state after a short transient. Nominal power, line-to-line voltage and frequency The nominal power in VA, the nominal line-to-line voltage in Vrms and the nominal system frequency in hertz. Turbine sweeping area m2. Problem Statement 2 Calculate the maximum power extraction of wind turbine by using aerodynamic equation generatots wind turbine.

Your model must then output the mechanical torque applied to the generator shaft. Between point A and point B the tracking characteristic is a straight line, the speed of point B must be greater than the speed of point A.

Bossanyi, Wind Energy Inuction. Energy is a necessary and essential ingredient of socio-economic development and economic growth.
