Reliability Evaluation of Transmission System Based on Cloud Model
Shuqiang Zhao · Power System and Clean Energy · 2010
The traditional evaluation of the transmission system reliability uses fixed values,but the original reliability data,subjected to impacts of the objective conditions is usually uncertain,which leads to the inaccuracy of the evaluation.In this paper,the cloud model is used to establish models and describe the reliability data of uncertainty,and then the reliability of transmission system is evaluated to obtain reliability index with form of cloud model,which is easy for operator to observe.The IEEE-RBTS and IEEE-RTS79 are also evaluated by the method and the results thus obtained show that the model expressed by the cloud model is more consistent with the human cognitive style of uncertainty,and prove the effectiveness of the method.
