“…HRTSim is intended for continuous methodically accurate three phase simulation of quasi-steady state and transient processes in equipment and EPS in whole for all possible operating conditions and any electric disturbance, including overvoltage [6], on an unlimited range and guaranteed instrumental accuracy. The possibility of obtaining complete and reliable information on the full significant spectrum of quasi-steady and transient processes in EPS using the hybrid tool is confirmed by comparing the results of simulation with full-scale data [7,8], as well as a number of successfully performed applied works [9][10][11][12].…”

Abstract. The determining factor for the selection of electrical equipment and switching devices is the short-circuit currents (SCC), for which the electrodynamics and thermal resistance is checked for the first, and for the second the switching capacity and wear-resistance. Also, the fault current is calculated for setting the relay protection and automation threshold. As is known, different digital simulation tools are used for calculating the SCC, in which inevitably use simplifications and limitations of mathematical models of equipment and EPS in whole. In this connection, the calculated values of SCC comprise, in some cases, significant error, so the validation is needed for used simulation tools. Proposed to use specialized hybrid software and hardware system for validation as the source of data needed to compare the simulation results of verified tools. It helps to determine their actual properties and capabilities, as well as to increase the reliability of decisions made on the basis of the calculated SCC, by understanding the causes and possible level of errors that arise.

Abstract. Numerical relay protection devices (NRP) are a promising area for the development of protection equipment for electric power systems. For its development, research and, in some cases, setting mathematical models are used. At the same time, the converting part of the NRP, which realizes the analog-to-digital conversion (ADC) of the analog input signal to the digital one, with which the microprocessor of the NRP works directly, is often ignored in models. The purpose of this work is to study the characteristics and parameters of the ADC, as well as to evaluate its impact on the operation of the ADC itself and need to take into account those or other characteristics in the simulation. To develop the ADC model, the C programming language was used. The ADC model is takes into account the cutoff frequency of the analog signal, sampling period, and number of samples required. The characteristics and parameters of the ADC are studied, their effect on the operation of the ADC is estimated. The result of this study -the ADC must be modeled as completely as possible, since its operation depends on the correct functioning of the NRP algorithm.

“…Due to the unity, continuity and high speed of the mentioned processes, the reliability and efficiency of power distribution grids depend on the level and the quality of their automation. Therefore, one of the main trends of the modern EPS development and improvement is their enhanced automatic controllability [1,2]. Since the last automated RFYS components of the EPS are electrical networks, the key solution to the challenging requirement are Flexible Alternative Current Transmission Systems (FACTS) [3].…”
