Solution features

  • Surge control — to protect compressors from surging, we integrate advanced algorithms with complementary process automation strategies
  • Compressor performance control — to meet process demands while maintaining operational limits, we offer efficient loading control
  • Decoupling control — to balance performance and surge control for optimal efficiency, we provide excellent decoupling control
  • Steam and gas turbine control; motor driver control — to provide seamless steam header control and machinery protection, we offer exceptional integrated controls


  • Reduces critical compressor inefficiencies and poor performance
  • Lowers risk of process disruption
  • Reduces risk of catastrophic compressor failures
  • Easy to follow control logic with intermediate results available in real-time

Boost safety and efficiency

With solutions and services for the fossil, hydro, and nuclear power market, Schneider Electric addresses all power configurations and needs for small to large reheat turbines. With more than four decades of experience, we have developed control solutions for general purpose and critical applications to boost safety and efficiency.

Solution features

  • Generator controls — control for megawatt, speed droop, isochronous, voltage, power factor, and MegaVar. We also offer over-temperature limiting, excitation limiting, load sharing, and load shedding.
  • Automatic voltage regulation (AVR) — AVR solutions include voltage and current control, voltage matching with “soft start,” and bus voltage matching for synchronizing.
  • Steam and gas turbine control — Integrated sequences and controls provide seamless steam header control and machinery protection for generators. We also provide control strategies for reheat steam turbines.


  • Protects critical assets from operation interruption and damage 
  • Enhances productivity and lifecycle of critical assets, such as steam turbines and generators
  • Enables performance monitoring
  • Enables improved asset management
  • Enables high-speed event recording

TMC retrofitting

TMC retrofits eliminate mystery boxes and outdated mechanical components. TriconexTM critical TMC controllers ensure 2oo3 voting for all trip inputs, electronic over-speed protection, online testing and repair, no single point of failure, and full instrumentation for automatic testing, and continuous diagnostics.

Solution features

Schneider Electric mechanical retrofit capabilities focus on actuators, power units, probes, and other physical components that deliver reliable, fault-tolerant performance. The solutions include:
  • Trip block assemblies (Quadvoter): fault-tolerant, online serviceable, and SIL-rated speed indication: active and passive speed probes receive the speed of the turbine and brackets
  • Custom hydraulic power units (HPU) retrofits: designed for high- or low-pressure hydraulic solutions 
  • Custom servo replacement and turbine redundant actuator control assembly (TRAC): fault-tolerant, online replaceable, off-the-shelf components for two or three servo solutions
  • Pneumatic actuator retrofits 
  • Custom LVDT brackets for redundant and triple-redundant valve position feedback and control
  • Thrust probes and brackets


  • Reduces installation time through strategic use of laser scanning and other advanced reverse engineering methods
  • Increases response and precision through high-pressure actuators and servo valves
  • Simplifies maintenance through the elimination of original equipment manufacturer (OEM) components
  • Increases service life and smoother operation with separation of lubricating oil and control oil
  • Improves redundancy with duplication or triplication of system components
  • More precise control — high-pressure servos and actuators provide excellent resolution with significantly lower hydraulic fluid flow providing increased speed and accuracy for control
