Abstract
For the problem that substation noise measurement is easily disturbed by external interference, a substation station boundary noise anti-interference monitoring scheme is proposed. Using the beam formation of the ring array in the modal domain for far-field directional pickup of substation noise to reduce the impact of steady-state interference on the measurement. Then the array output is converted into a single-channel signal, and the presence probability of substation noise at each time-frequency bin is estimated in real-time using an improved minimum-controlled recursive averaging algorithm, thus reducing the error caused by transient interference. The simulation results prove that the proposed method can effectively improve the accuracy of noise measurement.
