Abstract

Abstract: A system of risk assessment for secondary equipments of power system was proposed in this paper. Based on the characteristics of secondary equipment, a failure model was established by using the theory of risk assessment, reliability and full life cycle and a quantitative risk assessment model was established by combining status evaluation with risk assessment. A working mechanism was designed for quantitative risk assessment according to the data structure of the quantitative models. The proposed assessment system has been applied to the secondary equipment risk assessment of Guangdong power grid, which makes the power grid operation risk management change from superficial and qualitative assessment to elaborate and quantitative assessment. The assessment results provided a scientific basis for risk control management of secondary equipment.

Key words: secondary equipment of power system, risk assessment, status evaluation, assessment system
