“…In all investigated modes of operation of the power equipment, the value of the integration step is automatically selected based on the criteria for changing the rigidity of the nonlinear DAE system and ensuring the stability of the numerical method. The stable numerical solution was carried out when estimating the value of the methodical error determined by ( 1) and (2) [7].…”

The non-stationary mode characteristics of the generalized power equipment numerical experiments are analyzed, and the electrophysical dynamic characteristics and reliability of the IGBT in the power conversion process are studied. Based on the results of short-circuit numerical experiments and the steady-state mode of pulse width control, this paper introduces a method for analyzing the nonlinear dynamic process of IGBT drive modules during power conversion. The structure of a software algorithm for conducting numerical experiments to study the non-stationary operation mode of asynchronous electromechanical machines is proposed, and the numerical solution of transient nonlinear differential-algebraic equations of electrical equipment is described by gradient parameter method. The results of this study will help to study the dynamic nonlinear characteristics of the operation process of power and electrical equipment control and automation tools, and have practical significance for evaluating the computational efficiency and reliability of developing mathematical models in the next research work.

In practice, most mathematical calculations and analysis methods to study the transients of power electrical equipment are based on the use of its idealized mathematical description and, as a result, do not adequately reflect the real dynamic characteristics of the combined power systems. One of the reasons, the use of unreliable initial parameters of the mathematical model during numerical experiments. In this article, a method is developed, the synthesis of equivalent models of a given structure is carried out using methods of parametric identification of dynamic systems. Digital filters designed to increase the reliability of the measurement and information part of modern microprocessor systems are described. There is also an assessment of their speed and error in the numerical solution of the problem of restoring useful and primary electrical signals, as well as methodological and practical recommendations for choosing the sampling frequency of analog-digital transformations in time are given.

“…The complete system of equations for identifying the RLC parameters of the equivalent of an electric network relative to its switching buses is formed on the basis of differential and integral expressions of equations ( 1). This approach is well-known and, in particular, is described in sufficient detail in research [1][2][3][4][5][6][7][8].…”

“…In the solved equations, take the basic root mean square (effective) value: voltage and current, and need to introduce the basic frequency and integration step length. This is necessary, as it was shown in [1][2][3][4][5][6][7][8][9][10], to bring the residual equations to a unified system of calculus.…”

The article describes a method for dynamic identification of AC and DC hybrid power network parameters. The inaccuracy of the parameters of the electromechanical transient simulation model of the power system has caused the obvious difference between the simulation results and the actual measurement, which has restricted its online application. Over the years, the dynamic parameter identification technology based on field test and test has made great progress, but it is far from satisfactory and accurate. There is still a long research journey for the requirements of performance. The online identification method based on the actual dynamic parameters of the power system is a way to solve the problem. The article includes the main microprocessor modules for system parametric identification of load (SIP L) and an overhead power transmission line (SIP TL). The article will analyze the active electrical network and passive electrical network
