| Abstract: | According to statistics of the reliability indices for nation-wide 220 kV and above power transmission and transformation facilities and urban customer service,main factors of planned and unplanned outage for affecting 3 kinds of power transmission and transformation facilities including transformer,circuit breaker and overhead line were analyzed and evaluated,and main factors of scheduled and unscheduled interruption for affecting customer service reliability were also analyzed and evaluated.Through the analysis and comparison of reliability indices in last few years,the tendency of affecting reliability factors was put forward,which offer the beneficial basis for improving reliability of transmission and transformation facilities and urban customer service in the future. |
