Description

GE DS200LDCCG1AAA

Technical Specifications

  • Product Type: Load Demand and Control Board.
  • System Compatibility: GE Speedtronic Mark V.
  • Control Logic: Executes PID control algorithms for active power and frequency.

Functional Features

  • Active Power Control: Regulates fuel or steam valves to maintain the desired MW output.
  • Frequency Regulation: Responds to grid frequency deviations to provide primary frequency response.
  • Load Limiting: Enforces safe operating limits to prevent turbine overload.

Application Scenarios

  • Base Load Plants: Maintaining steady power output in combined-cycle power plants.
  • Peaking Plants: Rapid load ramping and frequency support in grid stabilization.

Performance Parameters

  • Control Accuracy: High-precision active power regulation with minimal steady-state error.
  • Ramp Rate: Supports programmable load ramp rates for smooth grid integration.

Material Composition

  • PCB: Industrial-grade multi-layer substrate with conformal coating.
  • Components: High-reliability microprocessors and precision analog front-end components.

Structural Characteristics

  • Dimensions: Standard Mark V board footprint.
  • Connectivity: High-density backplane connectors for seamless integration with R, S, and T cores.

Working Principle
The board receives the load setpoint from the operator and actual MW feedback from the grid. It compares these values, executes control algorithms, and outputs precise valve position commands to the servo control boards to adjust the turbine’s energy input.

Installation Requirements

  • Power down the Mark V system completely before installation.
  • Align the board precisely with the backplane guides to prevent pin damage.
  • Secure the board using captive screws to ensure proper grounding.

Usage Precautions

  • Always observe ESD precautions when handling.
  • Do not modify control parameters without proper authorization and system understanding.
  • Perform functional testing after installation to verify load control response.
