Abstract |
Background. The aim of the work is to experimentally testing of the possibility of telemetry data correction based on the data of automated electricity metering systems to reduce the deviation of the values of these data sources, which will improve the efficiency of energy systems management.
Materials and methods. To correct the data an algorithm based on the construction of the dependence «deviation – value of the automated accounting system» with its subsequent approximation by a step function and further correction of telemetry values, it is proposed to use. Verification of the algorithm performance was carried out on the data obtained for a number of connections of power facilities of the Far East of Russia.
Results. It is shown that the values of deviations for different connections and different time zones, in the case of the correction algorithm are significantly reduced. This is observed when working with data having both stationary and non-stationary character. The values of expectation and variance of corrected telemetry data flow are also reduced.
Conclusions. Application of the proposed algorithm of telemetry data correction leads in most cases to a significant reduction (two to three times) of the power estimation error. However, for the correct operation of the algorithm, it is necessary to ensure the acceptable quality of the data obtained through telemetry, otherwise the error will be reduced slightly, not more than a few percent.
