MHC to EHC Conversions

  • Modernizing low-pressure mechanical-hydraulic control equipment to a high-pressure electro-hydraulic system increases reliability
  • Exact valve positioning and faster response times to megawatt load, speed setpoint, or open/close/trip commands improves performance
  • Integrating mechanical diagnostic data into the Ovation control system enhances troubleshooting
  • PCMM 3D laser scans enable seamless integration of new and existing equipment, minimize field modifications and reduce installation time

Electronic Overspeed Protection

  • Precise speed, zero-speed and creep control helps protect the turbine from potentially catastrophic overspeed events
  • Redundant and failsafe design reduces nuisance trips and improves reliability
  • Options to retaining existing sensors or integrate custom sensor brackets with OEM equipment helps meet budget and schedule constraints 
Electronic Overspeed Protection - Emerson

Trip Upgrades

  • Reliable and rapid trip header depressurizing prohibits turbine overspeed conditions
  • Fault-tolerant design using 2-out-of-3 voting decreases nuisance trips
  • Online testing with pressure feedback to the control system eliminates the need for an actual turbine trip
  • Optional manual trip handle provides emergency hydraulic trip capability to enhance turbine protection
  • Hydraulic or lube oil filters remove particulate contamination to reduce
Trip Upgrades - Emerson

Digital Hydro Governor Retrofits

  • Replacing outdated mechanical control, feedback links and devices with modern hydraulics and instrumentation improves operation
  • Redundant hydraulic control and tripping functions increase reliability
  • Accurate, repeatable and responsive reaction to setpoint and frequency changes improves wicket gate control
  • Simplified design using fewer signal converters between the control system and field instrumentation reduces communication risks and maintenance costs
Digital Hydro Governor Retrofits

Position Feedback Upgrades

  • Accurate and repeatable valve stroke position feedback with high-speed response times improves turbine control and safety
  • Single, duplex or triplex redundancy reduces the risk of unplanned downtime
  • Modern design easily integrates into OEM assemblies, eliminates obsolescence issues, protects equipment and reduces maintenance costs
