If V < E, then the STATCOM behaves as a capacitor, generating reactive power. On the other hand, if V > E, then the STATCOM draws a lagging current, behaves as a reactor and absorbs reactive power. Thus the STATCOM can supple variable reactive power and regulate the voltage of the bus to which it is connected. Fig. 2: STATCOM
Series and Shunt Compensation of Transmission Lines:
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 …
