【 摘 要 】

Voltage sag, as an unavoidable power quality problem, has been attracted wide attention. Voltage sag risk assessment and early warning technology research have great significance for power supply companies and power users. This paper conducts the quantitative assessment of voltage sag risk based on the fault intensity and probability distribution of each component in power grids. In addition, a voltage sag automatic assessment and early warning platform is developed, which can visualize the failure probability of power grid components.
