Reconfiguration is necessary for a number of reasons, including the restoration of supply to consumers following fault events and for removing plant from service for the purposes of maintenance and refurbishment. The system described determines all switching plans effecting restoration of supply to parts of the network which have been isolated following a fault on a section of the network. Each switching plan, or reconfiguration option, is evaluated in terms of its electrical effects on the network and the optimal option is thus determined, using calculated post-reconfiguration electrical effects of each plan. It is proposed that the functionality of the system described in this paper could be integrated within a distribution automation scheme, resulting in several advantages for both the supplier and consumers. The algorithm employed in the system described in this paper is readily scaleable, as the search routines employed within the algorithm terminates at supply points in the network and the electrical analysis of the proposed network reconfiguration operations are intentionally simplified. In the UK context supply points would typically be the 33/11 kV primary substations. Accordingly, the search space does not become unmanageable and a large system is easily divisible into individual areas supplied by one (or more) primary substation(s). The system described in this paper has been applied to actual data from a UK Regional Electricity Company, and examples of the system's operation are included in the paper.","PeriodicalId":137272,"journal":{"name":"1999 IEEE Transmission and Distribution Conference (Cat.

Since the introduction of TR-XLPE in 1982, evolutionary and sometimes revolutionary improvements have been made by both the compound producer and cable manufacturer leading to enhanced cable performance and greater value to the power industry. For example, determined efforts by both compound producers and cable manufacturers over the past 20 years have led to dramatic improvements in compound and cable cleanliness and interface quality through advancements in contamination detection, compound production process, additive and resin quality, materials handling as well as in the cable manufacturing process with the advent of true-triple extrusion and dry cure crosslinking. These improvements have resulted in longer life cables based on accelerated wet electrical cable tests and as evidenced in actual field life. Most recently, TR-XLPE compound technology advances have resulted in a material that is easier for the cable manufacturer to process and somewhat easier for utilities to handle. Specific benefits of the recent advances include improved compound extrusion processability via enhanced scorch retardance and easier semicon strippability from the TR-XLPE, while maintaining the superior electrical performance that the industry has come to expect from TR-XLPE.","PeriodicalId":137272,"journal":{"name":"1999 IEEE Transmission and Distribution Conference (Cat.
