  1. Westar Energy Underground Networks

  2. Current System • Wichita • ~180 Network Transformers • Not including spot network transformers • Topeka • 26 Network Transformers • Rest of Topeka downtown served from one feed, with backup feed available

  3. Future of Network • Maintain current size • Continue to add new customers in downtown Wichita and Topeka to network • Add communications • Utilizing ETI RCMs

  4. Adding Communications • Difficult to predict exact load flows in a secondary network • Addition of communications devices allows the network to be monitored via SCADA

  5. ETI Remote Communication Modules • Devices used to monitor power flow from network protectors • Speaks DNP3 without needing translator • In the future, we will install communicating relays in network protectors • Communicating relays will perform the same communications functions as RCMs without the need for separate RCM box

  6. Adding Communications • Original plan was to add ETI Remote Communication Modules • Information sent back to SCADA system via Radius PDR Radios • Difficult to maintain line-of-sight from downtown Wichita to receiving antennae • Completed installation on 20 Vault Transformers

  7. Adding Communications
