Power Management System Integration – Gas Processing Plant
Comprehensive PMS integration for gas processing facility with redundant PLC architecture and advanced synchronization systems.
Project Overview
We delivered a comprehensive Power Management System (PMS) integration for a gas processing facility comprising 7 × 1270 kW, 3.3 kV gas generator units. This project involved integration of Generator Control Panels, Main Control Panel with redundant PLC architecture, bus synchronization systems, and comprehensive SCADA integration for centralized monitoring and control.
Project Scope & Complexity
The gas processing plant required a mission-critical power management system capable of handling multiple 1270 kW generators with high reliability and availability. The system needed to support automatic synchronization, load sharing, fault detection, and seamless switchover between generators. This was a complex integration involving multiple layers of control and communication.
System Components
Our solution included the following integrated components:
Generator Control Panels (GCP)
Individual panels for each generator featuring Woodward controller units, advanced protection relays, and automatic voltage regulator (AVR) systems for precise power quality control.
Main Control Panel (MCP)
