Power System Response to Frequency Transients

Frequency transients on electric power systems induce a response which is a complex function of system characteristics. This paper describes a digital data-gathering scheme and gives an analysis of the characteristic response obtained from a typical power system. Digital data-gathering permits analysis of transient response on a greatly expanded time scale and separation of the components for individual study. System response characteristics thus derived should contribute to improved power system control and stability when incorporated into on-line control computers.
