This paper presents a simple technique for the calculation of the eigenfrequencies of biconical cavities using the overlapping domain decomposition method in combination with the collocation method, which converges rapidly with increasing number of collocation point pairs and offers a reasonable computation speed.
Modern electric power systems (EPSs) is a complex, dynamic, non-linear and stiff system. Adequate simulation of processes in EPSs is a non-trivial task. During its solution, in most cases, relay protection (RP) devices are modeled as the simple blocks which are compering input signal with a setting and sending a signal to the commutation equipment. The character and duration of the transients in real...
The results of development and research of an universal (adaptable) mathematical model of hydraulic and steam prime movers of generators of electric power systems are presented in the paper. The created model allows modeling the continuous spectrum of processes in any particular type of these prime movers with the high completeness and adequacy, which is important for an adequate simulation of normal,...
This paper proposes the modeling automatic load-frequency control system implemented in the Hybrid real time simulator of electric power system (HRTSim). HRTSim developed for different simulation tasks does not impose any restrictions on the application of mathematical models and allows reproducing spectrum of normal, emergency and post-emergency processes in the electric power systems. The results...
This paper presents the features of the implementation of automatic exciting regulators (AER) models in the Hybrid Real-Time Power System Simulator (HRTSim). This simulator has unique abilities: simulation without decomposition, no restrictions on the dimension of the simulated power system, realtime simulation, exclusion of methodological error of simulation, usage of full and adequate models of...
The problem of creating meter of complex reflection coefficient based on the electromagnetic approach using E-plane cross-shaped divider is studied. System of the integral equation describing scattering waves by the E-cross is solved. Rigorous electromagnetic model of direct and inverse problems of five-port measurements of complex reflection coefficient is derived. Frequency dependencies of model...
We present the results of theoretical study on the effective generation of both terahertz radiation and high-order harmonics in the process of a single atom interaction with a multicolor laser field. Numerical results are discussed.
