Automating Emergency Power at Mosaic's K2 Plant

 

Implementing an SEL RTAC-Based Generator Transfer System

 

Dynamo partnered with The Mosaic Company's K2 Potash Plant in Saskatchewan to modernize the facility's emergency power transfer capabilities. The project replaced a complex manual transfer process with an SEL RTAC-based automation system designed to automatically coordinate load-shedding and generator transfer sequences following a loss of utility power. The result is a centralized system that improves visibility, automates critical switching sequences, and reduces reliance on manual intervention during emergency power events.

The Challenge

 

During a loss of utility power, operators were required to manually execute a complex sequence of load-shedding and generator transfer steps. The process involved multiple switching actions under high-stress conditions, increasing the potential for human error and limiting visibility into system status, alarms and event information. The upgrades also had to be implemented while minimizing disruption to ongoing plant operations.

 

The Solution

 

Dynamo implemented an SEL RTAC-based automation system that detects utility loss and automatically executes the required load-shedding and generator transfer sequences.

The system coordinates automated transfer actions across 50 breaker control circuits and 33 integrated protection relays.

Two HMI workstations provide operators with a centralized interface for monitoring, control and event analysis.

 

System Highlights

50 breaker control circuits upgraded

33 protection relays integrated

21 additional remote I/O points

Approximately 1,500 real-time data points monitored

2 HMI workstations

SEL RTAC automation platform

138kV / 15kV system voltage

 

Implementation

 

The project integrated protection relays into the SEL RTAC platform for centralized monitoring and control, upgraded breaker control circuits, deployed HMI workstations, and completed end-to-end testing and operator training. The SEL RTAC communicates with field devices through a secure network infrastructure, providing real-time visibility and control across the electrical system.

 

The Result

 

The automated system provides:

 

Automated outage response
Utility loss detection automatically initiates load-shedding and generator transfer sequences.

 

Enhanced monitoring and control
Operators have real-time visibility into data points, alarms, Sequence of Events information, metering and breaker status.

 

Reduced reliance on manual intervention
Automated sequencing, interlocks and permission-based controls reduce manual switching during emergency operations.

 

Scalable architecture
The modular SEL-based design provides a standardized approach for long-term maintainability and future expansion.
