Development Concept of Guaranteed Verification Electric Power System Simulation Tools and Its Realization

Abstract

Abstract. The analysis of existing problem reliability and verification of widespread electric power systems (EPS) simulation tools is presented in this article. Everything simulation tools are based on the using of numerical methods for ordinary differential equations. Described the concept of guaranteed verification EPS simulation tools and the structure of its realization are based using the Simulator having properties of continuous , without decomposition three-phase EPS simulation in real time and on an unlimited range with guaranteed accuracy. The information from the Simulator can be verified by using data only quasi-steady-state regime received from the SCADA and such Simulator can be applied as the standard model for verification any EPS simulation tools.

Analysis of dynamic behavior of the back-to-back High Voltage Direct Current link model as part of electrical power system

“…Properties and opportunities of B2B HVDC link will be analyzed via the B2B HVDC link model realized in the Matlab Simulink and the Hybrid Real Time Simulator (HRTSim) [5][6][7][8][9]. According to the [10,11] the following scenarios should carry out to confirm the benefits of B2B HVDC link: asynchronous connection of the EPS; short circuit on one side of the EPS; step change and reverse of transmitted power.…”

Comparison of qualities and capabilities of the “EUROSTAG” software and the Hybrid Real Time Power System Simulator

“…As a mathematical model of synchronous machines realized in HRTSim, a complete system of Park-Gorev equations of high accuracy is used, together with equations for the formation of three-phase coordinates a, b, c and equations for the mutual transformation of system variables d, q and a, b, c. Increased accuracy is achieved by modeling a larger number of damper circuits and taking into account the dependence of their parameters on frequency, namely three contours along the d-axis and four contours along the q-axis [3,7,8].…”

The concept of usage HRTSIM as a device for setting and certification of AVR

“…Therefore, microprocessor devices of AVR used in new or modernized power facilities must be tested in conditions close to the conditions of future operation to ensure system reliability of the UPS of Russia [4], which, moreover, is obligatory, according to the standards of JSC "SO UPS" [5]. In accordance with [5], testing of the AVR settings is carried out -either on a physical model of the power system, either on a mathematical model of the power system using a hardware-software complex of real-time power systems simulation.…”
