State‐space modelling of residential, commercial and peak demands

Abstract: The potential use of state-space modelling is evaluated through comparison with the existing multivariate ARMA models currently in use at Georgia Power Company for forecasting its residential sales, commercial sales and peak demand.

Assessing the Economics of Industrial Gas Turbine Cogeneration Applications

Abstract: Gas turbines are often used at industrial plants to generate electricity. However, turbines convert a greater portion of the input fuel into waste heat than into electricity. The degree to which this waste heat can be captured and used to produce steam, hot water, or simply hot air for drying, greatly improves the overall efficiency of the turbine system. This process is called cogeneration. There is no question that cogeneration can improve overall efficiencies. The question is whether cogeneration can be accomplished in an economic manner.This paper presents a straight-forward methodology for comparing the costs and benefits associated with cogeneration. All costs and savings are converted to a consistent before tax cent per kilowatt-hour basis. The inconsistencies encountered with simple payback analysis are avoided, as well as the complexities of discounted cash flow analysis. The effects of income taxes, depreciation, financing, and cogeneration load factor are incorporated.Copyright © 1992 by ASME

Insulation Tests for the Design and Uprating of Wood-Pole Transmission Lines

Abstract: Since the demonstration that the switching-surge strength of suspension insulators is markedly influenced by the tower from which it is suspended, considerable test work has been done to evaluate this effect on steel and aluminum structures. An extension of this test work to wood-pole structures shows unexpected advantages in switching-surge strength due principally to the smaller electrical mass of the wood, but in part to its insulating properties. New evidence is also obtained on the reseal property of wood insulation, though causal relationships are not yet understood. Impulse strength tests of wood-porcelain systems corroborate and expand on prior findings.

Factors Contributing to Improving Electric Service by Means of High-Speed Switching and Utilization of Stored Energy

Abstract: The quality of electric service as reflected through variations in motor speeds resulting principally from voltage surges is about as important to many manufacturing processes as is the continuity of such service. This paper sets forth the effects of voltage surges on an extremely speed-sensitive manufacturing process and describes how the effect can be minimized to the extent of becoming harmless. Test data are given which show the effects of voltage surges, of varying duration and magnitude, on the process, and the voltage surge is shown engraved in the finished product as the purchaser sees it. The maximum tolerable driving motor speed variation, without impairment to the product, is established and means are described for preventing a greater variation irrespective of the voltage surge intensity. An alarm system is described which is capable of instantly responding when variations in speed exceed tolerable limits. Use of a synchronous condenser, to supply energy during the interim of severe voltage disturbances or brief power failures, is effective in preventing motor-speed variations from exceeding the tolerable limits. These and other recent improvements will provide highly reliable electric service for the requirements of those manufacturing proccesses which are very exacting as to speed variations.
