Abstract. The motivation of the presented research is based on the need for development of new methods and tools for adequate real time simulation of automation control frequency and power regulators of generator played an important role in the planning, design and operation of electric power system. This paper proposes a Hybrid real time simulator of electric power system for simulation of automation control frequency and power regulators of generator. The obtained results of experimental researches of turbine emergency control of generator demonstrate high accuracy of the simulator and possibility of real-time simulation of all the processes in the electric power system without any decomposition and limitation on their duration, and the effectiveness of the proposed simulator in solving of the design, operational and research tasks of electric power system. IntroductionAccording to the well-known reasons, the simulation of electric power system (EPS) is the only effective tool for research of processes in EPS as a whole and solving of the design, operational and research tasks, including adequate settings of relay protection and automation system (RPA) of EPS [1,2]. Therefore, accurate modeling of RPA is one of the conditions for achieving a high adequacy of simulation EPS. At the same time simulation of RPA is quite complex problem that has significant practical value and can to solve a number of tasks. There are most urgent tasks [2,3]: The analysis and optimization of calculated settings of RPA;  The formation of methods and means of adequate settings of RPA (including automatic voltage regulator (ARV), Automatic frequency and power control (known as automatic generation control (AGC)), and others;  The development of new emergency control systems of EPS, including multi-agent systems; In particular, the simulation of AGC of generator is one of the most urgent tasks [4,5]. Especially important from a researcher's viewpoint is the depth of the simulation, as well as impact of the simulation depth to adequate modeling of the processes in EPS. The main criterion for the solution of this task is ability of realization of the AGC model in the particular simulated EPS with the maximum possibility of simulation depth of AGC model. Several approaches to solving the task of adequate simulation of AGC model have been implemented during the development of Hybrid real time simulator (HRTSim) of EPS, based on the concept of hybrid simulation and developed in Tomsk Polytechnic University [6,7]. The first version of AGC model created in 1988 was developed at analog simulation level via operational amplifiers and analog multipliers. In the current version, the AGC model has been realized at digital simulation level via microcontroller, which is a coprocessor of specialized hybrid processor (SHP) of electric

Up-to-date wide area measurement systems (WAMS) based on phasor measurement units (PMU) appeared at the very end of the 20 th century. Under present-day conditions, WAMS serve as the basis for information-measuring systems, which significantly improve power system control and operation. In practice, WAMS are mostly used for power system stability control and transient monitoring and visualization. This paper discusses the new opportunities for power system control quality improvement, resulting from PMU application for power system steady-state parameters' assessment. Firstly, better control is provided by online equivalent circuit parameters' identification using PMU measurement data and taking into account FACTS and other shunt and series compensation equipment. Secondly, the paper addresses the problems of "nodal" identification, which have taken on great importance recently due to the intensive development of small-scaled distributed generation. Based on PMU measurements of nodal voltages and incident transmission lines' electric currents, one can obtain online steady-state load characteristics, which can be used for dispatch control applications. Moreover, PMUs provide superaccelerated power flow calculations, which are of crucial importance for emergency automation, adjusted for prior operation. Such principles of emergency automation consist of the quick determination of control actions, aimed at power system stability maintenance in cases of any programmed faults' occurrence. It is known that such control is carried out by means of power flow calculations based on remote metering data. The proposed application and allocation of PMUs in the power system by means of combinatorial matrix transformation to triangle form give the possibility to perform accelerated node
