Squirrel Cage

To minimize the influence of power grid with wind power generation resulted by voltage sags with short duration, a paralleled integrated control device of squirrel-cage induction wind generator LVRT (Low Voltage Ride Through) is proposed which adds paralleled module circuits to conventional wind generator. With closed-loop hysteresis current control based on instantaneous reactive power theory and rated voltage control, this device can achieve reactive power compensation in normal operation and voltage stability when voltage sags. Power produced by wind generator is consumed during the sag and wind power generation system is connected to grid all the time. Simulation models about the device were built based on PSCAD / EMTDC platform and the analysis verifies the device’s achievement of LVRT.

The article analyzes the influence of wind speed prediction error on the size of the controlled operation zone of the storage. The equation for calculating the power at the output of the wind generator according to the known values of wind speed is given. It is shown that when the wind speed prediction error reaches a value of 20%, the controlled operation zone of the storage disappears. The necessity of comparing prediction methods with different data discreteness to ensure the minimum possible prediction error and determining the influence of data discreteness on the error is substantiated. The equations of the "predictor-corrector" scheme for the Adams, Heming, and Milne methods are given. Newton's second interpolation formula for interpolation/extrapolation is given at the end of the data table. The average relative error of MARE was used to assess the accuracy of the prediction. It is shown that the prediction error is smaller when using data with less discreteness. It is shown that when using the Adams method with a prediction horizon of up to 30 min, within ± 34% of the average energy value, the drive can be controlled or discharged in a controlled manner.
