TL;DR: In this article, the authors propose to reduce the size of the system by the use of equivalents to represent portions of the network beyond the area of immediate interest, but their use offers the possibility of reducing the problem to manageable proportions.
Abstract: The reinforcement of power-system interconnections intensifies the need for stability studies. The growing complexity of the networks tremendously increases the difficulties of performing these investigations. Present computers are not capable of representing a major system pool in detail and producing a study in reasonable time and at reasonable cost. One possible solution is to reduce the size of the system by the use of equivalents to represent portions of the network beyond the area of immediate interest. Stability equivalents are not perfect, but their use offers the possibility of reducing the problem to manageable proportions.

TL;DR: In this article, a gas-turbine package power plant was used to provide startup power for a 250MW steam-generating unit, and the performance of the excitation system during startup of large power-station auxiliary motors closely matched that previously calculated by a digital-computer program.
Abstract: A gas-turbine package power plant was used to provide startup power for a 250-MW steam-generating unit. Performance of the excitation system during startup of large power-station auxiliary motors closely matched that previously calculated by a digital-computer program. Results of the computer study and full- scale verification tests are presented. These results verified that the digital-computer program used accurately simulated the dynamic characteristics of the excitation system, generator, and motor. Based on this verification, it was concluded that further computer studies could be utilized with confidence to predict voltage dips at critical locations in the power system.
