A fast islanding detection tool can help power dispatchers monitor and control power system operations. Frequency monitoring network (FNET) is a low cost and quickly deployable wide-area phasor measurement system at the distribution system level. The frequency disturbance recorder (FDR) in FNET is actually a single-phase phasor measurement unit (PMU) installed at ordinary 120 V outlets in the sense...
Model validation is a highly recommended practice that should be performed periodically since the system model is very important for ensuring reliable and economic power system operation. Currently, field data are used to validate a specific model or an entire system. An FNET-based model validation procedure is proposed in this paper. It uses wide-area measurements to correct the response found from...
Analysis of power system dynamics helps to understand the operation of a power system. Therefore, it is significant to design and develop advanced visualization tools to interpret frequency, voltage magnitude, and phase angle information so that it can be presented to the operators in an intuitive manner. On the basis of the measurement data collected by widely-distributed frequency disturbance recorders...
Nation-wide, or largely synchronous activities, such as the World Cup or Super Bowl, have impacts on the power grid frequency response. This paper examines the influence of these sporting events on power system dynamics using data collected from the Frequency Monitoring Network (FNET). The frequency data of the German power grid during the 2010 World Cup semifinal game and the U.S. power system during...
Low frequency oscillations in the power grid can be classified into three types associated with power system events, non-obvious disturbances, and normal power system operations. A statistical analysis is introduced for the three types of oscillations in the Eastern Interconnection (EI) between 2009 and 2010 supported by the North American power Frequency Monitoring Network (FNET). Six “Type III”...
This paper discusses how the single phase phasor measurement data are used to validate the Oahu island grid model. The island system model is first established using available literature and proper assumptions. After validation via real system measurements, the physical model can truly represent the system dynamics. The model is used to study the integration of renewable source on the Oahu power grid.
Due to the influence of the local noise at the distribution level, the frequency curve obtained from the frequency disturbance recorder (FDR) unit is too non-stationary to observe its wave-front directly, which causes some problems in the event location estimation method. In this paper, a morphological filter (MF) is employed to extract the wave-front arrival time and the trend of the frequency curve...
