Systematically study on the static power-angle characteristics of a high voltage cable-wound generator prototype

High voltage cable-wound generator is a new kind of generator, which can be directly connected to the power grid. Basing on the fundamental theories of electrical machinery, the expressions of power-angle characteristics of high voltage cable-wound generator prototype with excitation regulator and without excitation regulator are deduced in this paper. Combining with the parameters of a high voltage cable-wound generator prototype and a typical conventional synchronous generator, the power-angle characteristics variation law of the high voltage cable-wound generator prototype and the conventional generator are obtained by simulation. It is found that the power-angle characteristics of the high voltage cable-wound generator prototype are better than that of the typical conventional generator.
