Power System Analysis, Evaluation & Implementation of ETAP PMS

ETAP helped OMIFCO to resolve their frequent breakdown of previously installed EMS/SCADA, automate their processes and reduce load shedding by implementing ETAP Real-Time

Project Manager, OMIFCO

Oman India Fertilizer Company (OMIFCO) had several issues with unplanned outages, disruptions in the supply of utilities, and problems with their power management control system. Additionally, there were issues with the visualization and control of the company's connection to the grid. These issues had a negative impact on the company's operations and resulted in financial losses.

OMIFCO (Oman India Fertilizer Company) is a joint venture between the governments of Oman and India to establish a modern petrochemical facility that produces ammonia and urea fertilizers. It is located at the Sur Industrial Estate in Oman.

Location: Sur, Oman

Year: 2018

Challenges

The company was facing several challenges related to their electrical systems and power management. These challenges included:

Missing Electrical Data and Power System Model
Lack of proper electrical data and system model
Lack of system historical events
Missing electrical data in Distributed Control System (DCS)
Limited system knowledge by the operator
Unplanned Outages and Process Interruptions
Frequent unplanned outages due to improper protective device setting
Nuisance load shedding triggers caused by power grid frequency fluctuations
Inadequate frequency relay setting and operation
Excessive process shutdown during load shedding events
Improper generator operating mode
Excessive voltage drop due to un-sequenced motor starting
Outdated and Faulty SCADA system
Substation control and HMI failures
Unable to effectively monitor energy usage
Manual grid synchronization with GTGs
No infrastructure for root cause analysis

Solutions

The co-engineering effort between ETAP and OMIFCO provided the plant with an integrated power management solution with a unique model-based approach:

Creating and validating entire plant’s electrical model
Performing exhaustive power system analysis
Finding out shortfalls of entire operations
Replacing existing BCU’s with latest ones
Segregating and interfacing all electrical data to ETAP
Tuning and implementing same model for PMS
Configuring a user-friendly HMI for easy electrical system operation
Installation of various interlocks preventing operational and human errors

Optimizing grid synchronization to prevent unnecessary system shutdowns Implemented ETAP Real-Time™ applications:

Advanced monitoring
Predictive simulation and what-if analysis
State and load estimation
Event playback and root cause analysis
Intelligent load shedding and validation
Grid synchronization
Tabular events and alarm management
Web-based HMI dashboards

Benefits

The installation and application of ETAP software has proven to be a great benefit to OMIFCO for operations and validation of their plant’s power system. The overall production increase by preventing unnecessary system shutdowns with predictive analysis.
