Аннотация

Online disturbance location is of significant importance to wide-area response-based situational awareness, stability analysis and control of the power systems. This paper presents an adaptive online disturbance location method that considers the anisotropy of the frequency propagation speed (FPS). The method geographically partitions the studied power system into several different regions offline. It then extracts the FPS vector for events occurring in each region. The method uses one event simulation for each region. The online simulations take into account changes in the generation, load and power grid topology. The location of the disturbance in each region is estimated specifically based on the speed vector of the region. Parallel computing is used to accelerate the estimation procedure. A part of the North and Central China interconnected power grid, which covers 7 provinces, is selected as an example to verify the effectiveness of the proposed disturbance location method and to analyze the speedup properties of the parallel computing.
