A new method is proposed for coordinating voltage/reactive-power control in a distribution system using a modified dynamic programming approach. The method is able to coordinate the action of substation on-load tap changer and the switching of substation and feeder capacitor banks that results in re...
solution is used in [2], where it is stated that if the voltage deviation index for a node, which can be presented as the difference in reference voltage magnitude and the nodal-voltage magnitude, is large enough, then the considered node is a candidate for the placement of a capacitor. ...
part of the power called reactive power, such as the establishment of the electromagnetic field takes the energy components, the share of the capacitor to establish electric power. current in the inductor components for power, the current lags the voltage 90 ℃. The current in the capacitor ...
2. POWER FACTOR CORRECTION The most easy and economical way to increase power factor, reducing then the reactive power consumption of the load, is the installation of capacitors. In figure 5 it has been added to the load a power capacitor installed in parallel. Power capacitors connected in ...
◆ It adopts IGBT power electronic devices perform control unit instructions quickly adjust the output reactive power; ◆ The thyristor contactor control combined with capacitor switching control, not only solve the inrush current, and shorten the thyristor operation time, reduce the heat loss of thyr...
