Q3. In an UPFC power control circuit, the transmission angle is changed from 0° to 60° The maximum value of injected voltage is 0.5 p.u, V = V.=1.0 p.u., X=1.0 p.u.. Determine the coordinate of a possible real power and receiving end reactive power demand which is common to the boundary of the respective control regions. Justify your answer with suitable illustrations. Q4. A STATCOM and a SVC are used for controlling the power in a transmission line. Vs= Vr=1.0 p.u , transmission angle is 10 degree, X=1.0 p.u., Maximum value of capacitive current for STATCOM is 0.9 p.u. Calculate the capacitive admittance such that the power transmitted using both the shunt FACTS devices are equal.
