Field performance of ambient modal estimation in small signal stability

2015 IEEE International Workshop on Applied Measurements for Power Systems (AMPS), 2015
Small signal stability is one focus of Wide Area Measurement Systems (WAMS). WAMS systems are becoming more widespread, driven by availability of synchrophasor data from Phasor Measurement Units (PMUs). In this paper, two methods capable of performing real-time small signal stability monitoring is evaluated by application to simulated data. Performance

Small-Signal Stability Analysis of Multi-Terminal VSC-Based DC Transmission Systems

IEEE Transactions on Power Systems, 2012
A model suitable for small-signal stability analysis and control design of multi-terminal dc networks is presented. A generic test network that combines conventional synchronous and offshore wind generation connected to shore via a dc network is used to ...

Impact of Large-Scale Wind Power Integration on Small Signal Stability Based on Stability Region Boundary

Sustainability, 2014
Up until now, study results on the impact of large-scale wind power integration on small signal stability have often been in conflict. Sometimes, the conclusions are even completely opposite, making people unable to agree on which is right.

Striving for small-signal stability

IEEE Circuits and Devices Magazine, 2001
In this article, based on Bode's definition of return ratio with respect to a single controlled source, the loop-based two-port algorithm and device-based gain-nulling are proposed for small-signal stability analysis. These two algorithms are complementary in terms of applicability, and they produce accurate stability information for single-loop ...

Small-signal stability analysis of delayed power system stabilizers

2014 Power Systems Computation Conference, 2014
This paper presents a stability analysis of power system stabilizers (PSS) for synchronous generators with inclusion of time delays. The paper shows that a time delay in the PSS feedback loop can improve the small-signal stability of a power system if the regulator gain is properly tuned.

Stability in Small Signal Common Base Amplifiers

IEEE Transactions on Circuits and Systems I: Regular Papers, 2013
This paper presents an analytical study of parasitic oscillation in video bandwidth common base amplifiers. We develop a series of progressively more complex small signal equivalent circuits based on the hybrid-π model [1], [2]. These circuits are developed such that the effect of each new parasitic element on circuit performance is evident.
