Using a DFIG–based wind farm for grid node reactive power compensation
Grid nodes voltages are not allowed to deviate excessively from nominal value. Appropriate measures should be taken to prevent such a deviation. The voltage difference between two nodes is strongly affected by reactive power flow. In contrast to frequency control, node voltage control must be achieved locally. This article investigates the use of a wind farm based on a doubly fed induction ...

What is a distribution transformer?
Distribution Transformer: An Essential Component of Power Distribution Systems As you go about your daily life, you probably take for granted that electricity is readily available to power your home and business. However, there is a complex system in place that allows for the efficient distribution of electrical power, and one key component of this system is the distribution transformer. What ...

How to choose the cross-sectional area of the power cable
The choice of the cross-sectional area of the power cable is related to the investment, the loss and voltage quality of the line, and the service life of the cable. If the cross-sectional area of the power cable is too small, the voltage quality will drop, the line loss will be too large, and the initial investment will be too high. Therefore, the appropriate cross-sectional area should be ...

Why the fossil-fuelled reactor fleet in France will not be affected by an evolution of the wind power capacity
Today's power electronics can confer high-performance adjustment capabilities on any technological object, including the frequency-power and voltage tuning of modern, synchronous-type wind turbines. However, this will not enable such devices to steadily produce electric power from an uncontrolled mechanical energy. Thus they cannot be considered independent generation units: the need to ...
