Reliability and survivability of electric power systems (EPS) depend on transient stability assessment (TSA). One of the most effective way to TSA is time-domain simulation. However, large-scale EPS mathematical model contains a stiff nonlinear system of high-order differential equations. Such system cannot be solved analytically. At the same time, numerical methods are imperfectly applied for such system due to limitation conditions. To make it appropriate, the EPS mathematical model is simplified and additional limitations are used. These simplifications and limitations reduce reliability of simulation results. Consequently, their validation is needed. The most reliable approach to provide it is to compare the simulation results with the field data. However, in practice, there are not enough data for such validation. This paper proposes an alternative approach for validationthe application of a reference model instead of field data. A hardware-software system HRTSim was used as a reference model. This power system simulator has all the necessary properties and capabilities to obtain reliable information required for comprehensive validation of transient stability calculations in EPSs. Main disturbances leading to instability in EPSs are investigated to conduct the validation (processes in cases of faults, single-phase auto-reclosing operation and power system interconnection). Fragments of corresponding experimental studies illustrate the efficiency of the proposed approach. Obtained results confirmed the possibility of the developed approach to identify the causes of numerical calculation errors and to determine disturbances calculated with the significant error. In addition, experimental studies have revealed that numerical calculations error depends on disturbances intensity.

This article summarizes the results of an analytical review of usage in Russian and the world information and telecommunications decision support systems for dispatching personnel of electric power systems (ITDSS DP EPS). The need for a fundamentally new and effective ITDSS DP EPS has been identified. A comparative evaluation of the effectiveness of the possible directions of research in the field of ITDSS DP EPS has been done. As the key methods for development of ITDSS DP EPS the numerical and hybrid approaches to electric power system (EPS) simulation were highlighted. Theoretical substantiation of unacceptability of the first variant allowed choosing the hybrid approach as a major which allows developing and applying the most effective methods, ways and means for every significant aspect of the problem of creation of ITDSS DP EPS. In accordance with this approach, two possible constructions of ITDSS DP EPS have been proposed, discussed and described briefly in the article.

“…An important task for electrical power engineering is to synthesize and diagnose the excitation systems of power-unit generators. This task can be solved effectively by using real-time simulation and Hardware-In-the-Loop technology [14][15][16]. Both special real-time systems and personal computers with Windows operating systems are used simultaneously for an implementation of the real-time models [11].…”

In this paper, testing and diagnosis methods for the static excitation systems of power plant synchronous generators using Hardware-In-the-Loop technology are described. These methods allow a physical excitation system to be connected to a real-time model of a power plant unit. A feature of a static excitation system is the presence of generator self-excitation—that is, when the input voltages of the excitation system are defined by a synchronous generator. These voltages are determining by the digital model, which creates additional difficulties with combining a digital model with a real excitation system. Various ways to solve this problem are described in this article; in particular, we focus on the option in which the gate-impulses of a thyristor converter are applied to the digital model by a real static excitation system. The real-time models are based on the method of average voltages in the integration step. This method is effective for providing numerical stability for the models of power schemes and their functioning in real time mode over a long period. A synchronization method for the calculation time of the model with real time is described. The adequacy of the described method is proved by the results of the static excitation system of synchronous generators testing in operating and fault modes.
