GE Electric | DS200LDCCH1AKA | Load Distribution Control Module
Product Description:
The GE DS200LDCCH1AKA is a Load Distribution Control Module for Speedtronic Mark V turbine control systems. It manages real-time load sharing and synchronization across multiple turbine units (e.g., gas/steam turbines in combined-cycle plants), ensuring balanced power generation and grid stability through precise frequency/phase matching.

Key Features:
- Cross-Unit Coordination – Dynamically balances loads between turbines.
- Auto-Synchronization – Matches phase/frequency before grid connection.
- Anti-Islanding Protection – Prevents out-of-sync grid reconnection.
- Adaptive Load Ramping – Smooth MW transitions during unit startups/shutdowns.
- Fault Resilience – Maintains stability during communication loss (fallback to local control).
- SIL-3 Certified – For critical grid-safety functions.
Primary Function & Purpose:
Coordinates real-time power output across turbine units to maintain grid-compliant frequency/voltage. Prevents overloads on individual turbines and enables “plug-and-play” integration of backup units during peak demand.
Typical Applications & Use Cases:
- Combined-Cycle Plants – Synchronizes gas/steam turbine-generators.
- Grid Peak Shaving – Activates standby turbines during high demand.
- Cogeneration Facilities – Balances industrial process steam/power output.
- Microgrid Systems – Manages multiple distributed energy resources (DERs).
- Black Start Operations – Coordinates sequential unit restarts after grid failure.
Application Fields:
Deployed in multi-unit power generation complexes:
- Utility Power Plants: CCPPs, coal-fired stations with auxiliary gas turbines.
- Independent Power Producers (IPPs): Renewable-hydrocarbon hybrid farms.
- Marine Power Systems: Naval vessel propulsion grids.
- Industrial Energy Hubs: Steel mills, refineries with captive power units.
