Modernize and retrofit turbine controls
Because overall production and plant safety are so dependent on turbomachinery performance, failures and unplanned outages can take a major toll in lost production and repair. Often, simply modernizing and retrofitting turbine controls can restore production, performance and profitability.
Turbomachinery power plant success
This Korean power plant successfully upgraded its turbomachinery equipment despite its remote location, limited local skilled resources and readily-available installation materials. As a result, it has achieved improved reliability, a simplified operating interface and adherence to regulations, all while providing a stable power supply to its customers.

Turbomachinery control solutions for power industry
Obtain generator control solutions including power control and automatic voltage regulation (AVR). Since overall production and safety are tied to a plant’s turbomachinery, it often represents the most critical capital equipment investment. Unplanned outages or failures incur significant cost in terms of lost production and repair; therefore enhancing TMC performance improves production capability and overall profitability.

Turbomachinery Control (TMC) for Mechanical Retrofit
Extend the life of TMC equipment and improve overall reliability with mechanical retrofit upgrades. Turbine-driven process plants must operate smoothly for a decade or more. This requires robust controls, reliable mechanical components, avoidance of spurious trips, and capabilities for online repair and testing. Enhancing visualization, diagnostics and simulation also helps extend time between turnarounds.
TMC Retrofitting
TMC retrofits eliminate mystery boxes and outdated mechanical components. TriconexTM safety systems ensures 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
> TMR servos
> Pneumatic actuator retrofits
> Custom LVDT brackets for redundant and triple-redundant valve position feedback and control
> Thrust probes and brackets
Benefits
> 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 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
