PROBLEMS

9.1. In Example 9-3 suppose that the generator's maximum reactive power generation

at bus

is limited to 125 Mvar. Recompute the rst-iteration value of the voltage

at bus

using the Gauss-Seidel method.

9.2. For the system of Fig. 9.2, complete the second iteration of the Gauss-Seidel

procedure using the rst-iteration bus voltages obtained in Examples 9.2 and 9.3.

Assume an acceleration factor of 1.6.

9.3.

A synchronous condenser, whose nactivc power capability is assumed to be

unlimitcd, is installed at load bus  or thc systc
