Abstract	Improving the reliability of power supply is one of the most important objectives in the smart grid framework. There are a plenty of investments in Xiamen, one of the six “high reliability demonstrated cities” in China, to explore strategies to improve the reliability in China. Reducing average interruption hours of customer (AIHC-1) is one of the main targets of the investments. Conventionally, this index is obtained according to the historical data. There is a lack of methodology to forecast AIHC-1. Therefore, it is difficult to assess the risk level of the network in the future to determine the maintenance planning, operation duty and upgrading schedule of power grid. To meet this challenge, the On-line Distribution System Risk Assessment System (ODSRAS) is designed to forecast the annual AIHC-1 in Xiamen. This system can quantitatively assess AIHC-1 in the given town, or in different substations and feeders. Therefore, pointed maintenance planning, operation duty and upgrading scheme of power grid can be made to improve the reliability according to the results from ODSRAS. In this paper, the framework and the HMI of ODSRAS are introduced. It is expected that the system in this paper can provide references for improving reliability by risk theory.
