Synchronous Generator Transient Control: Part II - Theory and Evaluation of New Control Techniques

This paper evaluates the application of bang-bang switching to the control of the system impedance presented to the generator, and proceeds to the evaluation of a similar form of control applied to excitation voltage. The general theory is explained, and both applications are supported by digital studies and experiments on a model power system. Attention is paid to the correlation between computed and measured responses and to the effects of erroneous switching times.
