Yokogawa has released a number of modules for the Stardom network-based control system aimed at the small- and medium-size turbomachinery and wind-power generation applications.

The 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.

There is a need for power-generation facilities that can be constructed within a short timeframe.

Demand for the steam turbines, hydro turbines, compressors, and other small- to medium-size turbomachinery installed in these facilities is also rising.

This type of machinery is also used in renewable energy facilities such as biomass and micro-hydro plants, and in conventional oil- and gas-fired power plants.

At the same time, the number of wind-power generation installations is also increasing in emerging countries.

To satisfy these needs, Yokogawa has augmented its module line-up for Stardom field control node (FCN) autonomous controllers by developing modules for small- to medium-size turbomachinery and wind-power generation applications.

For the conventional energy market, the company has also 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.

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 per cent of reading).

This is true even at speeds as low as 0.1Hz, ensuring that wind turbines can operate smoothly in all conditions.

Customers in the oil and gas industries are working hard to improve maintenance efficiency for remote wells.

To support them, Yokogawa has enhanced the CPU module for the FCN-RTU controller to ensure high reliability.

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.

The VDS monitoring and controlling software (Scada software) and other software for the Stardom platform now support Windows 7, ensuring that engineering, operation, and monitoring can all be performed under the latest operating system.

Stardom is an open network control system consisting of components with control, operation, and monitoring functionality.

It is said to combine 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.

Target markets include small- to medium-size power-generation facilities (steam turbines, wind turbines and hydropower generation facilities), small- to medium-size oil, chemical, iron and steel, and paper and pulp process plants, and oil and gas wells.

Other markets include widely distributed facilities such as those used in water and wastewater applications.

Applications include monitoring, operation, control, data collection, and data storage in small- to medium-size manufacturing facilities.
