4 Frequently Asked Questions about “Causes of deviation in wind farm power generation measurement - ID Solar Energy Systems”
What causes a wind farm to shut down?
The unpredictability of wind generation attributed to climatic conditions and low robustness can cause isolated tur-bine shutdowns and sometimes the disconnection of an entire wind farm from the electric power system (EPS).
How is a wind turbine model developed?
A wind turbine model and its control strategy are developed using the DIgSILENT simulation software. The control schemes for the generator side and the grid side converters are implemented to assure the power quality problems. With the simulation model, various circumstances and their effect on the performance of the wind farm are analysed.
What are the results of a wind farm simulation?
The results of the simulation are related to the recorded waveform to validate the model of the wind farm. This study will be useful for the turbine operators and manufacturers to assess the causes and severity of power quality issues well in advance to implement the necessary remedial measures. 1. Introduction
How is power quality measured in a wind farm?
According to IEC 61,400–21, the power quality events such as voltage fluctuation, harmonics and flicker are measured by power quality analysers connected at the selected locations in the wind farm. A wind turbine model and its control strategy are developed using the DIgSILENT simulation software.
The influence of yaw misalignment on turbine power output
They found that wake steering decreased the intermittent power generation and the standard deviation of the wind farm power generation reduced to a maximum of 72%.
