Surface Impedance and Synchronous Modes
نویسنده
چکیده
The concept of the surface impedance is applicable to the case, when obstacles on the surface of a vacuum chamber are small compared to characteristic dimensions of the problem. We apply this concept to the calculation of a synchronous mode that can propagate in a tube with slightly corrugated walls. We also show that such a mode can propagate in a pipe with a rough surface, or a perforated pipe with a large number of holes.

Impedance-Based Out-of-Step Protection of Generator in the Presence of STATCOM
This paper presents a novel impedance-based approach for out-of-step (OOS) protection of a synchronous generator. The most popular and commonly used approaches for detecting OOS conditions are based on the measurement of positive sequence impedance at relay location. However, FACTS devices change the measured impedance value and thus disrupt the performance of impedance-based relay function. In...
متن کاملCommissioning Experience from PEP-II HER Longitudinal Feedback
The DSP-based bunch-by-bunch feedback system installed in the PEPII high-energy ring (HER) has been used to damp instabilities induced by unwanted higher-order modes (HOMs) at beam currents up to 605 mA during commissioning. Beam pseudospectra calculated from feedback system data indicate the presence of coupled-bunch modes that coincide with a previously observed cavity mode (0-M-2). Bunch cur...
متن کاملCalculation of Impedance from Multibunch Synchronous Phases: Theory and Experimental Results
A novel beam-based method for measuring the longitudinal impedance spectrum is demonstrated using experimental data from the PEP-II High Energy Ring (HER). The method uses a digital longitudinal feedback system from which the charge and synchronous phase are measured for every bucket. Calculation of the transfer function from ll shape to synchronous phase yields the impedance seen by the beam a...
متن کاملModified Impedance-Based OOS Protection Based on On-Line Thévenin Equivalent Estimation
In this paper, a novel approach based on the Thévenin tracing is presented to modified conventional impedance-based out-of-step (OOS) protection. In conventional approach, the OOS detection is done by measuring positive sequence impedance. However, the measured impedance may be change due to different factors such as capacitor bank switching and reactive power compensators that it can cause the...
متن کاملInvestigation of STATCOM effects on synchronous generator impedance based LOF relay with considering a realistic model for the excitation system of the generator
This paper studies the effects of static synchronous compensator (STATCOM) on synchronous generator conventional loss of field (LOF) protection. To accomplish a comprehensive study, a typical and realistic excitation system is considered for the generator by using the phase-domain generator model available in the real-time-digital-simulator. Using such a system, LOF phenomenon is realistically ...
