VariStroke Linear Electro-Hydraulic Actuators for Steam Turbines

VariStroke Linear Electro-Hydraulic Actuators for Steam Turbines

Woodward solves steam turbine users’ #1 reliability problem . . . dirty oil!

The patented dirt tolerant and self-cleaning technology of Woodward‘s VariStroke actuators ensure greater overall reliability of your steam turbine. The VariStroke line of linear electro-hydraulic valve actuators operate mechanical-drive or generator-drive steam turbines. These linear actuators utilize a low-pressure, hydraulic oil source (typically turbine lube oil) to provide output shaft force. Their superb accuracy and resolution make them ideal for steam valve control and related turbine speed and load control, where turbine up-time and availability is essential.

The VariStroke line is configurable via a simple user-friendly, computer-based PC service tool, allowing users to easily configure, calibrate, and adjust all internal functions and response settings. Its integrated driver includes a 4-20 mA output channel to indicate output shaft (control valve) position, as well as unit alarm and shutdown relay outputs for use as unit health and status indications. The 4-20 mA demand inputs and dual-redundant shaft position sensors allow it to continue to operate even with demand input or feedback sensor failures, ensuring extended run-times between forced outages and on-line system repair.

The total installed cost for this fully-integrated actuator is low because it is completely assembled and tested at the factory, greatly reducing OEM and end-user fabrication, testing, and site assembly time. In retrofit applications, the VariStroke actuator can be used to directly replace the existing servo system. This saves costly repairs to existing and aging servos, eliminates the difficulty of obtaining spare parts for obsolete equipment, and reduces calibration time and difficulty.

Woodward‘s quality of design sets a new benchmark in actuator reliability and performance. With its robust shaft and bearing design, the VariStroke actuator surpasses traditional actuators in reliability by eliminating leaks common with base mounted steam valve racks and the associated arc- induced continuous side load on the output shaft. After being tested to over 1 million shaft cycles, with over 1,000 lbs of side force continuously applied to the output shaft, the VariStroke was leak free.

VariStroke’s versatile design provides the flexibility to integrate the best solution to fit your turbine application. The actuator design enables users to adjust output shaft stroke range to fit their specific needs. Turbine manufacturers and owners now can easily set maximum stroke position from 50 – 100% of factory listed maximum stroke range, saving time and the cost of modifying expensive valve racks and related linkages.

Solve your reliability problems by putting VariStroke actuators
to work on your steam and hydro turbines……..

Woodward Vertex Compressor Control

Woodward Vertex Compressor Control

Woodward‘s Vertex Compressor Control product line

The Vertex control product line is designed to control and protect industrial sized axial or centrifugal compressors. This controller includes specifically designed algorithms and logic to start, stop, control, and protect industrial compressors driven by a stationary speed motors, variable frequency drive motors, or turbines. OEM qualified algorithms are used within the Vertex control for straight-through, iso-cooled, double flow, stand alone, and back-to-back compressor applications.

The Vertex controller is field configurable allowing users to configure/select the specific control algorithm required for the specific compressor loop and application. The control’s special stage-to-stage and performance controller decoupling logic allows stable control during normal compressor operation as well as during plant upsets, minimizing process over or undershoot conditions.

Refer to product specification for more information – 03437b Vertex Product Specification

This purpose-built controller has the control, protection, and decoupling logic
required for one or two recycle loop compressor applications. OEM qualified
algorithms are used to ensure that proper start sequences are followed, proper and
accurate compressor load calculations are used, and proper protection and recovery
actions are performed.
Basic functionality includes:

 Motor or Turbine Drive Interface Logic
 Inlet Throttle Valve Control
 Inlet Guide Vane Control
 Recycle Valve(s) Control
 Anti-Surge Control (1 or 2 Recycle Loops)
 Performance Control (suction or discharge pressure or process flow)
 Surge Anticipation Logic
 Surge Protection Logic
 Surge Recovery Logic
 Load Sharing (Parallel compressors, up to five Trains)

Designed to function as a plant DCS node the Vertex controller can be configured to
interface with the plant DCS via hardwired inputs/output signals or serial or Ethernet
communications. With the capability to monitor and control all compressor based
functions (i.e. bearing temperatures, vibration levels, control oil levels, etc.) the
Vertex controller is ideal for use as a cost-effective compressor control/protection as
well as a plant DCS monitoring node.
Designed to replace old obsolete anti-surge controllers, the Vertex can be configured
to function like these controllers but uses faster scan rates, improved surge
anticipation logic, and one integrated package for all control functions (anti-surge
control loop 1, anti-surge control loop 2, and performance control). Also, for load
sharing function, no need for additional Master controller hardware.


The Vertex control is packaged in an industrial hardened enclosure designed to be mounted within a system control panel located in a plant control room or next to the compressor. The control’s user-friendly front panel serves as both a programming station and operator control panel (OCP). This user-friendly front panel allows engineers to access and program the unit to the specific plant’s requirements, and plant operators to easily start/stop the compressor and enable/disable any control mode. The controller’s 8” graphical display allows operators to view actual and setpoint values from the same screen, simplifying compressor operation.

Cyber Security Bulletin – Meltdown/Spectre Exploit

The early January 2018, ICS-CERT released information disclosed in December 2017 on two side-channel exploits, Meltdown and Spectre. Meltdown affects Intel based chips, however Spectre impacts additional chips such as ARM, AMD and NXP. Spectre affects a variety of operating systems and chips and relies on “Speculative Execution.

The following information is from CERT: CPU hardware implementations are vulnerable to side-channel attacks referred to as Meltdown and Spectre. Both Spectre and Meltdown take advantage of the ability to extract information from instructions that have executed on a CPU using the CPU cache as a side channel. These attacks are described in detail by Google Project Zero, the Institute of Applied Information Processing and Communications (IAIK) at Graz University of Technology (TU Graz) and Anders Fogh. The issues are organized into three variants:
 Variant 1 (CVE-2017-5753, Spectre): Bounds check bypass
 Variant 2 (CVE-2017-5715, also Spectre): Branch target injection
 Variant 3 (CVE-2017-5754, Meltdown): Rogue data cache load, memory access permission check performed after kernel memory read
An attacker able to execute code with user privileges can achieve various impacts. The Meltdown attack allows reading of kernel memory from user space. This can result in privilege escalation, disclosure of sensitive information, or it can weaken kernel-level protections, such as KASLR. The Spectre attack can allow inter-process or intra-process data leaks.
To execute code locally, an attacker would require a valid account or independent compromise of the target. Attacks using JavaScript in web browsers are possible. Multi-user and multi-tenant Windows systems (including virtualized and cloud environments) likely face the greatest risk. Systems used to browse arbitrary web sites are also at risk. Single-user systems that do not readily provide a way for attackers to execute code locally face/have significantly lower risk.

Affected Units
Customers using Microsoft Windows operating systems, specifically the SOS application. Legacy Pentium/NT, MicroNet™, and Atlas PC have low risk – see below.
HMI systems and engineering workstations that may be attached to a Woodward control system utilize Microsoft Windows and are potentially impacted.
See notes under “Corrective Actions.”
Woodward controls (MicroNet, MicroNet+, Atlas, 505), with the exception of the NT CPU and the Atlas PC are not impacted by Meltdown or Spectre.
Users have reported issues with SOS on Windows systems patched by KB4056892. You can view Windows Update history by viewing Control PanelSystem and SecurityWindows UpdateView Update History. It is recommended to avoid installing this knowledge base update.
Microsoft has released a new patch KB4088776 to address this issue.

Impact to MicroNet Simplex NT CPU and Atlas PC (NT version) with Pentium CPUs:
Web browsing and JavaScript hosting is not available on the NT CPU and Atlas PC controls. Local code execution will require physical access to the control and upload of an unauthorized executable to the control to exploit. Since this is a side-channel exploit, data can only be observed, and not directly manipulated.
Note: Woodward’s current industrial control products (including MicroNet Plus, MicroNet TMR, Atlas II, 505 and Flex500) are not directly impacted by Meltdown or Spectre.

Corrective Action
Windows-based HMI and Engineering Workstation Computers:
Woodward normally recommends that the end-user’s IT department or other group responsible for maintaining these computers keep these machines updated with the latest Microsoft security patches. However, in the case of Spectre and Meltdown, there have been significant issues with the Windows patches issued by Microsoft. You can view Windows Update history by viewing Control PanelSystem and SecurityWindows UpdateView Update History.
Please see notes below regarding recommendations on specific patches:
– Users have reported issues with SOS on Windows systems patched by KB4056892. Recommend not installing this knowledge base update. Microsoft has released a new patch KB4088776 to address this issue.
– If the user has installed KB4056892 and SOS exhibits issues, the user should uninstall KB4056892. If the user is unable to uninstall this update or uninstall does not address the issue, DCOM configuration in Windows may need to be changed.
– KB4088776 addresses issues created by KB4056892 regarding DCOM and OPC (thus impacting SOS server functionality)

MicroNet Simplex and Atlas PC systems with Pentium CPU:
Implement physical security so that unauthorized code updates cannot be made.
