March 15, 2011 - Yokogawa Electric Corporation releases 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 turbomachinery, 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.
The newly developed control modules include a servo module that controls the rotational speed of small- to medium-size turbomachinery 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 high accuracy (±0.1% of reading). This is true even at speeds as low as 0.1 Hz, ensuring that wind turbines can operate smoothly in all conditions, from strong winds to gentle breezes.
For the conventional energy market, Yokogawa also has improved the reliability and 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. Specifically, the module now has the same error check and correct (ECC) 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 enhanced its DNP3 software to comply with the latest DNP specifications and cover a wider range of SCADA applications.
About STARDOM
STARDOM is an open network control system consisting of components with control, operation, and monitoring functionality, and it combines the reliability of a DCS and the versatility and economy of a PLC. The autonomous controllers at the core of STARDOM have the same control and monitoring functions found in a PLC as well as the information distribution functions of a PC. They are widely used as intelligent remote terminal units (RTU) in distributed applications such as natural gas and oil wells. When used in combination, the FCN/FCJ autonomous controllers and FAST/TOOLS SCADA software give increased flexibility in distributed applications.
