Complex Dissipating Energy Flow Method for Forced Oscillation Source Location

چکیده
In this letter we propose an extension of the Dissipating Energy Flow (DEF) method for locating sources forced oscillations (FOs), based on energy function constructed by complex integral approach, which call Complex DEF (CDEF). To trace FO, study scalar projection CDEF in a specific direction plane. We show simulated cases that alternative has good performance where original fails.

Using Effective Generator Impedance for Forced Oscillation Source Location
Locating the sources of forced low-frequency oscillations in power systems is an important problem. A number of proposed methods demonstrate their practical usefulness, but all of them rely on strong modeling assumptions and provide poor performance in certain cases for reasons still not well understood. This paper proposes a systematic method for locating the source of a forced oscillation by ...
متن کاملComplex Fluids in Energy Dissipating Systems
The development of engineered systems for energy dissipation (or absorption) during impacts or vibrations is an increasing need in our society, mainly for human protection applications, but also for ensuring the right performance of different sort of devices, facilities or installations. In the last decade, new energy dissipating composites based on the use of certain complex fluids have flouri...
متن کاملExpiratory flow limitation during mechanical ventilation detected by the forced oscillation method.
We have previously observed large phasic variations of respiratory mechanical impedance in chronic obstructive pulmonary disease (COPD) patients mechanically-ventilated for acute respiratory failure, and postulated that they were due to expiratory flow limitation (EFL). The aim of this study was to test that assumption experimentally and to assess the value of impedance for automatic and noninv...

متن کاملSource Location of Forced Oscillations Using Synchrophasor and SCADA Data
Recent advances in synchrophasor based oscillation monitoring algorithms have allowed engineers to detect oscillation issues that may have previously gone undetected. Although such an oscillation can be flagged and its oscillation shape can indicate the general vicinity of its source, low number of synchrophasors means that a specific generator or load that is the root cause of an oscillation c...
