Landfill Power Plant: SCADA System

EvoLogic, Inc - Industrial Automation - 2011

Wonderware InTouch software, running on a Windows XP workstation, is the backbone of this SCADA system. The workstation serves a double purpose as the real-time operator interface and as a historical database server.

Description:  At this site, landfill gas is used to power four, 16-cylinder Caterpillar engines.  The engines turn generators, which produce electricity that is sold to the utility company.  This SCADA system was installed to provide continuous monitoring and data management for the entire gas collection and generation system. 

System Specifications: 

Any alarm condition of the gas supply equipment or generation system is immediately reported using WIN-911 software.  The call-out phone number is chosen according to a weekly schedule, and re-calls are initiated until any outstanding alarm is acknowledged by the call recipient.

Six Panasonic network cameras produce live video feeds, which can be viewed through a web browser on or off site.  The operator has the ability to pan, tilt, zoom, and focus, each camera individually through the browser.

* 4 engine generators continuously produce electricity from landfill gas.

* 6 network cameras provide live video feeds for remote viewing through a web browser.

* 9 PLC and computer data sources feed hundreds of analog and Boolean data values to the SCADA server.

* 35 individual dial out alarms notify the on-call operator with specific alarm details.

Information in the database is

accessed to generate custom or

pre-configured trends.

Reports are automatically generated from the database at the end of each month.  These reports are submitted to the DNR as proof of air permit compliance.

A secure VPN connection gives authorized users full featured monitoring and control over the system from any computer with Internet access.

Each different alarm produces a unique message using text to speech technology.
