Voith’s range of digital steam turbine controllers has been extended with the new TurCon DTc. This compact model can be set-up quickly and easily to perform all standard control functions, says Voith.
It is “pre-engineered” for steam turbines of all power classes, meaning that the user only has “to set the selected parameters, which keeps installation work to a minimum”. There is no need to buy additional special software, Voith notes, while data can be displayed at any time via the control panel or via the connected control system.
The TurCon DTc consists of two rugged assemblies: intuitive 7” TFT-LCD
touchscreen control panel with integrated CPU; and a remote I/O unit. The controller can be integrated into existing Industry 4.0 environments via a standardised Ethernet interface with Modbus TCP or OPC. An optional control panel or PC can be connected via the LAN interface, for example as part of a commissioning process or remote monitoring set-up.
The option of simultaneously controlling a maximum of 4 HP and 2 LP control valves is another special feature of the TurCon DTc. This means that there is no need to adjust the valves mechanically using a camshaft or via a separate valve co-ordinator (split range).
Other key elements helping to ensure reliability and availability include the use of three frequency inputs with 2-out-of-3 voting for the speed sensors.
An integrated simulation mode allows commissioning personnel to check whether the parameter settings are actually correct and improve them if necessary prior to hot commissioning. This minimises the risk of damage due to incorrect parameters.
The TurCon DTc archives the last 1000 status, warning and alarm messages with a time stamp, allowing process flows and malfunctions to be easily identified and traced. As a result, fast, targeted optimisations are possible.
