Enhancing Reliability in Urban MV Distribution Networks through Cross Connection Strategies

This paper discusses the potential improvements in supply reliability for urban medium voltage (MV) distribution networks using cross connection models. Authors Vladimir Blazek and Petr Skala from Brno University of Technology explore various measures, including remote-controlled devices and failure signaling to dispatch centers. Their analysis includes a comparison of costs associated with different network configurations as well as the advantages of cross connections, such as increased manipulation capability and backup supply during failures, while also noting the economic drawbacks.

  1. Urban MV Distribution Network with Cross Connection Vladimir BLAZEK, Petr SKALA Brno University of Technology Czech Republic

  2. Some of Possibilities of Supply Reliability Improvement • Remote controlled devices • Signalling of failure to the dispatching centre • Implementation of other measures • Cross connection

  3. Cross Connection

  4. Model of MV Network4 consistently transposed feeders CC CC

  5. Annual CostsofAnalogous Variants of the Network

  6. ConclusionCross Connection Disadvantages: • Higher annual cost by aprox. 4 per cent • From clearly economical point of view, the use of cross connection is ineffective Advantages: • Increase of manipulation capability • Ring connection of various feeders is possible • Back-up supply in case of double failure
