The number of transmission messages is small when the traditional power system monitoring methods collect signals, Therefore, a fault dynamic monitoring method of intelligent power system telecontrol dispatching based on improved fault tree is proposed. The telecontrol communication model of intelligent power system is constructed. The communication signal of telecontrol dispatching channel is collected. The parameter of signal time-domain characteristic is measured. The time-domain waveform can pass through the zero period to get the carrier frequency range, judge whether the system telecontrol dispatching has fault, and analyze the fault mode by improving the graphical logic deduction of fault tree. A comparative experiment is carried out. Compared with the traditional methods, the results show that the design method can improve the number of packet transmission per unit time, increase the network traffic, and ensure that the communication network has very low load in the dynamic monitoring process.
