Abstract
This paper describes principles worked out for the design of frequency-power regulation in a power system. The method of analysis is based upon general ideas of frequency-response methods and offers new possibilities for evaluating the regulation properties of power stations. It is aimed to give efficient regulation with the least possible effort. This is attained by matching the feedback data for the governors to the characteristics of the machines and the actual disturbances in the network. This method has been worked out for the Swedish power system. The power system is described briefly, the characteristics of the elements in the regulation loop are given, and the measurements of the frequency-response curve of the power system are reviewed.
