摘要

This paper describes various developments to improve reliability in urban power distribution networks. Actual implementation of different methods is addressed. The benefits are calculated according to the benefits achieved through regulatory incentives and through benefits obtained in asset management The actual implementation in Helsinki presents both traditional and advanced smart grid implementations. The network supervision and control was previously limited to transmission and primary substation level only. Now with the implementation of both distribution automation and 100% coverage of smart meters, the entire grid from transmission to customer level is monitored and controlled. The impact of the chosen development methods on reliability indices in Helsinki is described. The future smart grid actions in Helsinki are also included. The main contribution of the paper is the holistic view on reliability improvement in urban distribution networks and the description of the actual implementations. The results show that with well planned and implemented actions the customer interruption costs and SAIDI in urban networks can be reduced by 50%.
