Abstract

A centralized system for automatic load-frequency control (ALFC) has been developed by the Siberian Division of the Central Computing Center of the Power Industry and realized on the basis of a commercial OMRON controller that performs all control functions. The algorithmic and software support of ALFC performs several new functions, i.e., helps to produce control actions on regulating stations with allowance for the specified daily output, perform second-after-second (cumulative sum) accounting for the power produced by a power station due to participation in the control, initiate combined regulation of power flow and frequency (APFR), ensure maintenance of a 1-sec archive with a depth of over 30 days for any telemetry (TM) used in the ALFC, etc. The software has been developed with the help of special language based on the IEC 1131-3 standard.
