GE Vernova Integrated Plant Control DCS System

System Overview

GE Vernova's Integrated Plant Control DCS (Distributed Control System) is an efficient, consistent, and secure solution for managing complex plant processes.

The system improves the operational efficiency of critical subsystems by responding to load changes in real time and maintaining optimal conditions at every stage of the water/steam cycle.

Core Control Functions

1. Boiler Control and Protection

• Burner management, ignition system control
• Steam pressure monitoring and regulation
• Boiler blowdown control to reduce corrosion and impurity accumulation
• Furnace purge, flame monitoring, boiler trip protection
• Automatic water level and steam pressure adjustment to reduce accident risks

2. Water/Steam Circulation Control and Protection

• Covering main steam, auxiliary steam, feedwater pumps, high/low pressure heating, condensing, deaerator, and other systems
• Maximizes the conversion of boiler energy into turbine power
• Equipped with fail-safe logic, self-diagnostics, and fault reporting

3. Auxiliary System Control

Can replace PLC controllers, managing:

• Water treatment, wastewater treatment, air compressors, continuous emissions monitoring systems, emergency diesel generators, etc.
• Material handling systems such as coal ash conveying and stackers

4. Power Distribution Management

• Manages medium and low voltage switchgear to ensure power supply sequencing and safety
• Supports automatic/manual switching, automatically enabling backup power in the event of a fault

5. Steam turbine auxiliary control

• Controls for lubricating oil, jacking oil, cranking gear, shaft seal steam, generator cooling, and other systems

6. Flue gas desulfurization integration

• Supports limestone and seawater desulfurization systems
