COMPUTERS IN THE COMPLEX-AUTOMATION SYSTEMS OF ELECTRICAL POWER GRIDS

A general discussion is presented of the possible role of computers in maintaining economy regimes at manual-controlled partially-automated power plants. The reducing of fuel consumption by 1% may save 150,000-200,000 rubles per 1,000 Mw installed capacity. The optimization of load distribution among power plants and of electrical and thermal load distribution among power-producing units may bring about a fuel saving of a few percentages which would quickly (from 3 months to 1.5 years) pay the cost of the computers making such an optimization possible. A combined system of frequency-and-active-power control is being developed by the Kiev Institute of Automation and Energoset'proyekt (Moscow); the power-system operation will be based on predictive calculations for the system and automatic operating control at individual plants. The problems arising with power exchanges over low-capacity interconnection ties and d-c interconnections are noted. A sketch showing the recommended disposition of computers in a complicated power system is presented. An IPK-2 special computing device for determining fuel-consumption relative increments is mentioned.
