Overspeed Safety Systems for Steam Turbines

The platform ranges from the simplex version (ProTech-SX) to a full TMR based control that also monitors up to 10 different machinery sensors/devices (ProTech TPS) to provide a full blanket of protection for your equipment. The new platform leverages decades of experience from Woodward’s ProTech 203 platform. Many improvements to the platform make it easier to use, maintain, customize, and standardize. In addition, security functionality is implemented to meet the market’s new Cyber Security requirements.

MicroNet™ Safety Module

Woodward’s MicroNet™ Safety Module PLC can be applied to any size steam, gas, or hydro turbine, or plant process equipment. This safety PLC’s fast (12 millisecond) response time, 0.5 to 32 000 rpm speed range, and integrated overspeed and acceleration detection/protection functionality, make it ideal for application on critical high-speed rotating motors, compressor, turbines or engines.The Micronet™ Safety Module is IEC61508 SIL-3 Certified and API670 & API612 Compliant.

ProTech®-SX Safety System with Integrated Overspeed Protection

The Woodward ProTech-SX is a safety programmable logic controller (PLC) with integrated overspeed protection designed to safely shut down any plant process equipment, engine, or steam, gas, or hydro turbine upon sensing a safety event. This stand-alone safety system accepts two speed inputs and seven discrete/analog inputs, uses programmed logic to determine when a safety event has occurred, then issues system shutdown commands and alarms. The Woodward uses five fast-acting, configurable relay ouputs and a speed meter output to interface with/command the specific system or device being protected.

QuickTrip - Trip Block Assembly

Safety certified hydraulic trip block assembly for use in industrial steam turbine shutdown systems. The QuickTrip trip block assembly is designed for use in steam, gas, and hydro turbine shutdown systems for quick and reliable dumping of the turbine’s trip oil header. This integrated trip block assembly is intended for use on mechanical-drive or generator-drive steam turbines that use low pressure (5-25 bar / 73-363 psi) hydraulic trip oil headers. The QuickTrip’s fault tolerant design makes it ideal for critical steam turbine applications, where turbine up-time and availability are essential. This trip block assembly’s 2-out-of-3 voting design provides users with a very high level of system reliability as well as compliance with industry standard API-670. Certified for use in IEC61508 SIL-3 systems.

MSHS - H-Block Trip Valve

H-Block Trip Valve

The MSHS H-Block trip manifold is designed to provide a pre-packaged 4-valve trip arrangement, thus simplifying installation for the end-user. Simplifying the packaging of [4] trip valves in [1] housing keeps already complex systems in turbine trip headers from becoming confusing and helps to avoid nuisance trips.
