A Weather Dependent Failure Rate Model for Overhead Lines

Abstract:

In power system planning and operation, accurate assessment of overhead lines outage rate is essential for making timely decisions. The overhead lines are often influenced by many random events, such as accidents and weather conditions, resulting in power outages. Especially, the reliability of the overhead lines is subjected to weather conditions to a great extent[9]. At present, research about weather conditions dependent reliability is abundant, but many of them are based on synthetical weather, little of them base on specific weather conditions such as typhoon and thunder .This paper proposed outage model of overhead lines dependent upon typhoon an thunder. In power system planning and operation, accurate assessment of failure rate is essential for making informed decisions, The outage model proposed in this paper has significant meaning for the research of risk assessment of power systems.
