Other Abstract

According to the situation that rainfall weather frequently causes secondary geological hazards, leading to local transmission line outage, a risk evaluation method is established. Firstly, the ways of electrical equipment failure probability influenced by secondary geological hazards caused by rainfall weather are analyzed. Then, according to meteorological and geological monitoring data, related parameters of geological hazards are evaluated and fault probability of tower deformation and line breakage of transmission line is quantified. Based on Monte Carlo simulation and optimal load shedding model, risk indicators are built using risk theory to recognize weakness of power system under geological hazards. Considering structure and operating status of power grid, framework of data collection and processing and information feedback is put forward in the proposed method. Finally, the proposed analytical method is verified with simulations of a certain regional power grid. Results show that power system risk gradually increases with scope expansion and hazard severity increase.
