    The unit commitment program for the GE 412 digital process control computer optimizes the shutdown and startup of generating units so as to achieve minimum system fuel costs. Additional savings in the order of two to fifteen dollars per year per MW of installed capacity are estimated [1] over those gained from a feasible schedule. The program is flexible and considers numerous special operating re... View full abstract»

    The objective of this study was to determine the feasibility of using Dynamic Programming1 to solve the generating unit commitment problem. The main difficulty connected with this problem, is that factorial N, a large number for even a relatively small N, plays a central role in any straightforward formulation of the problem.

    The maximum principle by Pontryagin is applied to the problem of determining the operation of a hydro-steam generating system for the minimum generating costs. The general dispatch formulas are derived for power systems with hydroelectric plants having fixed head, varying head, and hydraulic coupling, both with and without river transport delay and wave phenomena. Techniques are demonstrated which... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1497 KB)

    This paper describes how a digital computer program intended for system planning studies was used to investigate several questions related to pumped storage planning and operation. Among the items investigated were reservoir size, the influence of cycle efficiency on pumped storage capacity factor and operating cost, and the effect of load forecasting deviations on system economy. A brief descript... View full abstract»

    While the economic factors associated with the planning and design of a pumped storage hydro project must include system operation concepts, the day to day operation of a given pumped hydro project presents a different set of economic decisions. In this connection, the array of data or information that must be presented to the dispatcher is, of necessity, different in form from that presented to t... View full abstract»

    A method is presented for optimizing the weekly or daily dispatch of a power system consisting of 16 hydro plants, 4 thermal plants, and a pumped storage plant. The main features of the method are: treatment of hydro plants in cascade on a river and its tributaries with freedom for heads to vary at each plant; allowances for hydro units out of service; optimum thermal unit scheduling, including th...

    This paper describes a new computational approach to the problem of the most economical operation of hydraulic plants in electric power systems, employing L. S. Pontryagin's maximum principle. The economical operation of a simplified model system is treated and the long range operation of a multireservoir system is considered. The relaxation method is successfully applied to the solution of optima... View full abstract»

    Decision tables for real time process control logically present the solution to a problem and directly replace flowcharts. A decision table is a self-contained description of the solution to a complex decision problem. It presents all pertinent variables, the rules for combining possible conditions, and actions desired. The power of a decision table is that format and programming are independent o... View full abstract»

    Previous designs of capacitive potential devices are briefly reviewed with an explanation of why they were not suitable for revenue metering. A new design metering accuracy potential device, capable of meeting 0.3-accuracy class at 400 VA, is presented. Theoretical error formulas are developed and confirmed by actual test results. Adverse effects such as temperature change, frequency shift, voltag... View full abstract»

    Response characteristics of a resistor divider whose high-and low-voltage arms consists of different characteristic elements are investigated and theoretical response equations to the unit step, triangular wave, and exponential front wave are derived. Detailed numerical calculations are carried out on the response of such a resistor divider and error for measuring the impulse chopped on the front ... View full abstract»

    No single anchor can perform equally well in all types of soils, hence the need for various types of anchors to suit the surrounding media. The intention of this paper is to present the various considerations in design, selection, testing, and application of EHS (extra-high strength) anchors under different conditions.

    Since early 1946, when grounding of the 34.5-kV system of the Wisconsin Michigan Power Company was established through installation of a Peterson coil, very complete records have been maintained with regard to all ground faults on the system. The results of an analysis of these records, covering 19 years of operation with resonant grounding, are contained in the paper. Resonant neutral grounding w... View full abstract»
