The new method is the combination of local compensation at each load and distribution line compensation. In the method, local capacitors at each load are determined to increase power factor of load to an expected value first and then a number of capacitors are placed in distribution lines with two factors, location and capacity by using …

The output power capability of the parallel hybrid excitation generator (PHEG), consisting of permanent magnet machine part and reluctance machine part, is restricted by the flow of the reactive power in its two parts. To improve this issue, a compensation method using middle parallel capacitors is proposed. This method compensates both capacitive and …
Series compensation reduces the series impedance of the line which causes voltage drop and is the most important factor in finding the maximum power transmission capability of a line (Eq. (5.70)). A, C and D constants are functions of Z and therefore the also ...
The direction of reactive power flow can be reversed by making V 2 >V 1. The magnitude of reactive power flow is determined by the voltage difference between point A and B. When R is ignored, the reactive power flow, Q is given by the following formula: Q = V 2 (V 1 − V 2) / X. The ideal situation is when V 1 = V 2, and reactive …

Fig. 1a shows a typical three-phase distribution system, in which a group of inductive linear load, non-linear load and shunt power capacitor are connected simultaneously. Shunt power capacitor C P is used to compensate for the main inductive current generated by the linear load, while D-CAP to compensate for the rest inductive …

The capacitive reactive power is generated through the capacitance producing devices serially or shunt connected to a load [20], [21], [22]. A significant amount of studies was devoted to the methods to produce reactive power, such as DSTATCOMs [7], [23], [24], STATCOM [7], [24], [25], and real electrical capacitors [26].
Here X C = capacitive reactance of the series capacitor bank per phase and X L is the total inductive reactance of the line/phase. In practice, X C may be so selected that the factor (X L — X C) sin Φ r becomes negative and equals (in magnitude) R cos Φ r so that ΔV becomes zero. The ratio X C /X L is called "compensation factor" and when expressed as a …
As important reactive power equipment, parallel compensation capacitors play a key role in improving the power quality and the structure of the power system. At present, the detection of parallel compensation capacitors generally takes offline test, and the fault in operation mainly relies on the protection device action to be removed. However, there is a …
