Discussion on Impact of Load Rate on Distribution Network Reliability

The high-load operation has a great influence on component reliability and distribution network reliability. The evaluation results of component failure rates obtained by traditional evaluation methods often differ greatly from the actual statistical results. Therefore, this paper divides the state of load into three states of light load, heavy load and overload, and establishes the failure rate-load model. The sequential Monte-Carlo simulation method is used to investigate the influence of load factors on the failure rate of components. The results show that the influence of overload condition on distribution network reliability is significant, and the average failure rate of components will increase significantly with the increase of overload condition time.
