The publication  demonstrated a detailed description of the hybrid simulation concept of electrical power systems (EPS). This article is its continuation  and presents the description of the practical application experience of the hybrid real-time power system simulator (HRTSim) for the purpose of solving specific tasks regarding the control of the Tyumen power system (TPS). The article presents fragments of fast turbine valving control which, in our Russian practice, is one of the main emergency control tools that regulate the capacity of an electric power station. EPS’s operational stability depends on the adjustment of this automation to a large extent, therefore any incorrect adjustment can lead to significant perturbation or loss of stability which already happened in the past. With the use of the HRTSim, we managed to solve one of the most complex tasks in the electric power industry of Russia – to adequately adjust the fast turbine valving control of a high-power thermal electric power station – Surgut GRES-2 Power Station which we were not able to do in the past. The adequateness of the simulation of a turbine and fast turbine valving control of power unit is confirmed by comparing them with the data of real experiments at a real facility. Following the research results, we created a method for the selection of the best adjustment parameters for the fast turbine valving control at Surgut GRES-2 Power Station which can be applied at other electric power stations of Russia as well. The work was performed as part of project No. МГ-2017/04/1 «Development of a Hardware and Software Platform for the All-Mode Real Time Simulation of Smart Grids» which is implemented with the assistance of Non-Commercial Partnership «Global Energy». The group of authors won the International Award «Global Energy» in the Youth Section in 2016.
