“…At the same time, the accuracy of solution depends on the frequency instrumental error of integrated microelectronic element base used in RM for the analog solution. The instrumental error is ≤1% according to experimental investigations of RM in frequency range (0‐1000 Hz). Further, the comparison of quasi‐steady regime of modeled EPS with SCADA data is carried out.…”

Summary Reliability and efficiency of electric power systems (EPS) operation depend on the adequacy of information about quasi‐state and transient processes in EPS used for their research, design, and operation. A value of short‐circuit currents (SCC), especially their maximum values, is one of the important information used for different tasks. The difficulty of obtaining this information is the need to use a large‐scale EPS mathematical model for SCC calculation. The total mathematical model of any large‐scale EPS is a stiff and nonlinear system of differential equations of high order. Such system cannot be solved analytically. Satisfactory solution is also impossible by using the numerical approach that leads to the need for applying simplifications and limitations reducing the adequacy of simulation results. Therefore, each solution should be validated. The comparison of simulation results with the field data is the most reliable way of validation. However, the acceptable amount of field data cannot be obtained in the foreseeable future in view of the obvious variety of EPS modes, especially emergency ones. An alternative way of validation is suggested in the paper: the using of an adequate reference model instead of field data. The experimental sample of hybrid real‐time power system simulator having the necessary properties and capabilities is used as the reference model. The indicated possibility of SCC calculation validation is proved by the experimental studies shown in the paper.

The phase shifting transformer in the electric power system (EPS) provides more efficient control of EPS modes by voltage and active power flow regulation. However, nowadays quasi-steady and transient processes in the EPS become more complicated. As a result, the commonly used simulation tools apply decomposition of EPS processes to quasi-steady and transient, simplification of mathematical models of EPS elements, limitation of the simulation time interval. Mentioned simplifications and limitations in general lead to an uncertain loss of completeness of EPS modeling. The concept of software and hardware tools of phase shifting transformer simulation, presented in the article, allows to solve this problem. The software and hardware of phase shifting transformer simulation are the tools of hybrid simulation, which include analog, digital, and physical approaches of the simulation. The analog approach is the solution of the differential equations system, describing the phase shifting transformer processes by continuous implicit integration. The digital approach provides the control of the electronic switches, the phase shifting transformer parameters, such as leakage inductance, active resistance etc. The physical approach is the connection and switching in the EPS elements as in real EPS. The article presents the all-mode thyristor-controlled phase shifting transformer model, developed by hybrid simulation approach and adapted for use in the Hybrid Real Time Power System Simulator developed in Tomsk polytechnic university. The appropriate research of phase shifting transformer in the EPS was carried out by Hybrid Real Time Power System Simulator, in which the Tomsk EPS (region of Russia where there is a problem of non-synchronous operation of the northern and southern parts) is implemented. By means of the Tomsk EPS model and developed phase shifting transformer model, the purpose of which was to interconnect two asynchronously operating parts of the Tomsk EPS and experimental research were carried out.
