Lansing Board of Water & Light

Lansing, Michigan

Located near downtown Lansing, Michigan, this plant was constructed in the early 1920’s and has since undergone several rebuilding and expansion projects. The Eckert Station includes six electric generating units ranging from 41 megawatts (MW) capacity to 77 MW. The six units are capable of generating a total of 351 MW of electricity. The BWL entered the thermal energy business in 1919 when it bought the steam distribution and production facilities of the Michigan Power Company. Through the 1950’s, production facilities were added to keep pace with an expanding service area. Today the Moore’s Park Steam Plant uses low cost coal to generate up to 660,000 lbs/hr of steam, which is distributed to its customers through nearly 14 miles of steam line.

Situation

  • Plant was equipped with older, manually operated Push-Button / Selector Switch Controls and Annunciator Panels for Fly Ash and Bottom Ash Recovery Operations. These components were becoming obsolete, un-reliable, and inefficient for the operators to use.
  • Alarm Notification was not centralized and did not store or acknowledge alarms securely
  • Inconvenient Line Change-over tasks were required by the operators took up extra time
  • Lack of System Monitoring at Local or Remote Stations and no Web-based / LAN displays
  • Had no way to integrate existing Ash Handling Controls into balance of plant operations

New Solution

  • Design, fabricate, and support the installation of an Allen-Bradley Control Logix PLC Platform
  • Design and implement a Supervisory Control and Data Acquisition (SCADA) System based on Rockwell Automation’s RS View SE Software and Industrial PC Monitors
  • Design HMI & System Monitoring Screens that are familiar to Plant Operations
  • Develop and deploy Local, Remote, and Web-based (Intranet) Support access to the system
  • Develop database to store historic operational data and “new condition” events
  • Work closely with LBW&L Plant Personnel to connect PLC / HMI / Data to existing Plant Network

Results

  • Central and Distributed Alarm Display Screens and Acknowledgement
  • Networked Operator Interface Displays for HMI / SCADA functions
  • Familiar and Standard off-the-shelf PLC & HMI Controls from Local Supply & Support channels
  • Compatibility for future plant control additions and expansion of control and monitoring
  • Schedule and run Ash removal as needed—saving energy and wear on pipes and valves
