Abstract

Abstract: At present, the electromechanical transient model and parameters are generally used for simulation analysis of the LCC-HVDC transmission system with the power grid commutation converter as the core, but there is no practical error evaluation method for checking the parameters. Aiming at the electromechanical transient model and key parameters of the DC transmission control system, this paper proposes an error evaluation method for independent calculation of divided intervals and overall verification of configuration weights, based on the similarity method and analytic hierarchy process idea for power system simulation credibility evaluation, and a reasonable error evaluation standard is also given. Firstly the time series of the HVDC transmission system simulation and experiment are divided into multiple intervals, and the analytic hierarchy process (AHP) method is used to configure the weight coefficients for each interval. And then the error index of each interval and the overall error index are calculated. The validity of the error evaluation method is verified with test data of actual DC projects. The proposed method can evaluate the simulation accuracy and overall simulation effect of each stage of the entire time series, and can provide a technical support for the parameter verification of the electromechanical transient model of the DC transmission control system.

Key words: high-voltage direct current transmission system, electromechanical transient model, parameter checking, analytic hierarchy process, error evaluation method
