Model Validation Using Synchrophasor Data - - A Synchrophasor Success Story
Mathematical models – from models of individual transmission elements and power plant components to production cost models and system models -are used for every aspect of power system planning and operations. When a generator or system does not act in the way that its models predict, the mismatch between reality and the model-based expectations can lead to severe disturbances and costly equipme...
متن کاملObservability and Estimation Methods Using Synchrophasor
Intermittent generations such as large-scale renewable energy increases the risk of instability in a power grid. In this paper, we introduce the concept of observability and its computational algorithms for power networks equipped with synchrophasors. The goal is to estimate the angles and its derivatives around unstable trajectories, the information that is critical for the detection of power ...
متن کاملInternational Journal of Smart Grid and Clean Energy Synchrophasor measurement based damping estimation and oscillation mode detection using FFT-CWT approach in Japan campus WAMS
The low voltage level synchrophasor measurement data are investigated to estimate the damping ratio and to detect any oscillation mode using Fast Fourier Transform (FFT) and Continuous Wavelet Transform (CWT). Complex Morlet (CM) is selected as a mother wavelet function considering its ability to reveal time and frequency localization simultaneously. A Two Area Four Machine System (TAFMS) model...
متن کاملTracking State Estimation in Distribution Networks Using Distribution-level Synchrophasor Data
State estimation is often a challenging task in distribution systems due to numerous nodes and limited number of measurement sources. As a result, distribution system state estimation is often not real-time; instead, it is done once every 5 to 15 minutes, e.g., when smart meter measurements are available. Accordingly, this paper proposes a novel method for tracking state estimation in distribut...
متن کاملMultimode Oscillation and Mode Competition in High-Frequency Gyrotons
Stable operation in a single mode is an important goal of high-power gyrotrons. Both multimoding and switching into ynwanted modes can lead to lower efficiency and undesirable heating of components not designed to accommodate parasitic modes. We have extensively studied mode behavior in a pulsed 100-kW, 140-GHz gyrotron using a variety of mixing techniques. As a result, a number of multimoding ...
