Title: problem sets would have been useful
Review: This is a text on the numerical analysis of a power circuit. Common methods used elsewhere, like Newton-Raphson, Gauss-Seidel and Jacobi, are applied to these circuits.It builds up elementary circuit theory. But now explicit consideration has to be given to the impedances of overhead lines or underground cables. Because the circuits being considered can span hundreds or thousands of kilometers. Whereas in a circuit on the table of a lab, wiring impedances can often be ignored.You need some background in power systems, but not necessarily in solving these numerically. The book could have been usefully enhanced with problem sets for each chapter, to let the reader test her understanding.
