The use of power-limiting reactances with large turbo-alternators

In large electric power systems the maintenance of a very high degree of reliability, that is, continuity and uniformity of service, must be the constant aim and is one of the principal problems of the engineer. While the problems during the earlier years of central station work often appeared very difficult, the advent of the large capacity, high-speed turbo-generators coupled to systems containing hundreds of miles of transmission lines, made them much more complex and they took on a far more serious aspect.
