Control System Modules Handle Upstream Oil And Gas Applications

Yokogawa Electric Corp. has released a number of new modules for the Stardom network-based control system. The new modules include control modules with the high speed and reliability required for small- to medium-size turbo machinery, a frequency input module that can accurately measure the speed of even slowly rotating wind turbine blades and an upgraded CPU module for oil and gas upstream processes that features improved reliability and greater memory capacity.

Yokogawa has augmented its module lineup for Stardom field control node (FCN) autonomous controllers by developing new modules for small- to medium-size turbo machinery and wind power generation applications. For the conventional energy market, Yokogawa also has enhanced the functionality of the FCN-RTU low-power autonomous controller that was developed for the control of oil and gas wellheads distributed over a wide area.

The newly developed control modules include a servo module that controls the rotational speed of small- to medium-size turbo machinery and a high-speed protection module that protects machines by detecting anomalies such as excessive rotation speeds. The frequency input module measures rotational speeds with accuracy of ±0.1% of the reading, even at speeds as low as 0.1 Hz.

The module now has the same error check and correct memory found in high-end PCs, and the memory capacity has been doubled to facilitate the long-term storage of gas volume data and other on-site information. Yokogawa has also upgraded its DNP3 software to comply with the latest DNP specifications and cover a wider range of SCADA applications.
