SWPA Completes Acceptance Test
Southwestern Power Administration (SWPA), Springfield, Mo., completed the final acceptance test of its EMS after demonstrating system availability in excess of 99.9 percent over a 60-day test period. The system, delivered by Advanced Control Systems (ACS), is the manufacturer`s first large-scale, open system UNIX-based EMS to complete final acceptance testing.
The final acceptance test included a continuous availability test for all critical equipment and system functions. Availability tests were only conducted when all RTUs were connected to the master station, allowing ACS to demonstrate the industry`s first operational system with DNP 3.0 Protocol between a master and RTU. All results were monitored by SWPA in accordance with strictly defined quality assurance acceptance procedures developed to meet SWPA specifications.
