Abstract

As installed wind energy capacity increase, the low Frequency oscillation parameters may change. In order to accurately detect the low Frequency oscillation parameters, a algorithm based on the matrix pencil and stabilization diagram was proposed. It’s difficult to get the order of oscillation signal, so it’s necessary to find a proper method to determine the order. We calculate the order of oscillation signal stabilization diagram by using the stabilization diagram. After this, The matrix pencil algorithm is used to extract the frequency and damping of each component of system signal. In the end, the simulation results show when SNR is high, it still accurately identified the parameters in the different systems.
