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.

Today mathematical simulation is practically sole method, with no alternative, for obtaining comprehensive and reliable information about regimes and processes in electrical power systems. This is due to the impossibility of making field tests in real EPS, and significant limits of physical models. Therefore, according to official standards and regulatory documents of JSC "SO UPS", the development of the hardware-software simulators for real-time power system simulation with the purpose of automatic voltage regulators setting and certification is the most urgent issue. This paper proposes the Hybrid Real-Time Power System Simulator usage as the solution. The performed studies and tests (partially demonstrated in the article) show the possibility of such simulator usage for the stated aims.

Abstract. Development and implementation of new AutomaticGeneration Control (AGC) algorithms requires testing them on a model that adequately simulates primary energetic, information and control processes. In this article an implementation of a test platform based on HRTSim (Hybrid Real Time Simulator) and SCADA CK-2007 (which is widely used by the System Operator of Russia) is proposed. Testing of AGC algorithms on the test platform based on the same SCADA system that is used in operation allows to exclude errors associated with the transfer of AGC algorithms and settings from the test platform to a real power system. A power system including relay protection, automatic control systems and emergency control automatics can be accurately simulated on HRTSim. Besides the information commonly used by conventional AGC systems HRTSim is able to provide a resemblance of Phasor Measurement Unit (PMU) measurements (information about rotor angles, magnitudes and phase angles of currents and voltages etc.). The additional information significantly expands the number of possible AGC algorithms so the test platform is useful in modern AGC system developing. The obtained test results confirm that the proposed system is applicable for the tasks mentioned above.
