In this paper, the application of the Prony method for the estimation of dominant inter-area oscillations modes in large power systems is presented. The main goal of this paper is to compare the dominant oscillations modes extracted by the Prony method with those obtained by Eigen-value analysis. In order to achieve that, two testing systems have been designed. The first system is a multimachin...

Unified power flow controller (UPFC), as one of the most important FACTS devices, can be used to increase the damping of power system oscillation. The effect rate of this controller on increasing oscillation damping depends on the appropriate selection of input controlling signal, optimal selection of UPFC controlling parameters, and its proper position in power system. In this paper, the capab...

a portable and light pneumatic branch shake system was designed and manufactured in this research for harvesting fruits that can be harvested by shaking branch. required air flow and electric current are provided for operating system from category containing electrical generator and air compressor on wheelbarrows and portable chassis. vibration is equipped by programmable logic controller (plc)...

The objective of the present study is to investigate spectral purity of a CW magnetron for a microwave power transmission system of Solar Power Satellites, or other radio applications. Oscillation spectra of a 2.45GHz oven magnetron were measured and the purity of the spectra is discussed. A filament-off magnetron has narrow bandwidth. In some conditions, however, the oscillation spectrum has F...

This paper presents an approach for studying Very Low-Frequency Oscillations (VLFOs) between 0.03 and 0.08 Hz that have been observed on Irelands All-Island transmission system. Previous work by Ireland's TSO has found the occurrence of VLFO is linked to generation dispatch synchronous machines with governor control. study verifies previous research analyses sensitivities such as inertia...

The main objective of this paper is to investigate the enhancement of damping the power system oscillation via coordinated design of the Power System Stabilizer (PSS) and STATic COMpensator (STATCOM) controllers. The design problem of PSS and STATCOM controllers are formulated as an optimization problem. Using the developed linearized model of a power system equipped with STATCOM-based stabiliz...

We employ a novel data-enabled predictive control (DeePC) algorithm in voltage source converter (VSC)-based high-voltage DC (HVDC) stations to perform safe and optimal wide-area for power system oscillation damping. Conventional is model based. However, practice, detailed accurate parametric models are rarely available. In contrast, the DeePC uses only input-output data measured from unknown pr...
