Classification of Telemetry Parameters Errors on the Example of Electric Power Industry Dispatching Center for Automation Task of Verification Process

Abstract

The article considers an overview of the methods of classification of telemetric systems, presents the results of the system analysis of telemetry errors arising in the process of controlling electric power systems. Principles of classification of telemetry parameter errors are obtained using the example of the electric power dispatching center. The application area of each method of classification is shown. A generalized description of the sources of information about possible errors in telemetry is proposed. A general description of the process of detecting errors and restoring the reliability of the telemetry parameters of the dispatching center of the joint-stock company “System Operator of the United Power System” of the Russian Federation without using automation is introduced. The data transmission standards used in the power industry are given. Examples of using primary telemetry parameters for the calculation of secondary ones are described. The ways of restoring the reliability of parameters containing gross errors are enumerated. A table example summarizing the properties of telemetry parameters for making a conclusion about the accuracy and elimination of errors of reference data is given. The automation process of the detection and recovery of the verification of telemetry parameters, in general, is demonstrated. The concepts for using artificial neural networks for automation process of verifying telemetry parameters are mentioned.
