Systems Engineering

Supervisory Control and Data Acquisition (SCADA) systems give system operators a visual real-time view of their water or wastewater processes.  Utilizing a powerful industrial computer, SCADA graphical display software, and remote monitoring equipment, the SCADA system provides a "System Dashboard" for remote management of their system.  Radio telemetry is the typical backbone for data transmission from remote sites to a central office location.  Remote Terminal Units (RTU's) are used to take inputs from field instruments that allow system operating parameters and their corresponding values (ex:  tank levels, pressures, flows, pump motor status, chlorine residual, etc.) to be displayed on the graphical interface screen at the office.  The remote locations have SCADA control panels that incorporate programmable logic controllers (PLC’s) and radios to gather the digital information from the remote sites and then send them to the SCADA computer location.

In addition to displaying the current status of the system, the SCADA computer utilizies specialized hardware or software packages that can alarm operators via e-mails or text messages and also log information from the system to be used in regulatory reports.

All process control functions are resident at each site’s Remote Terminal Unit.  Absent the communication with the Master Terminal Unit, the RTU will maintain local control.

The SCADA Computer and Human Machine Interface Software is not necessary to sustain system operations in the event of system failure.  The Programmable Logic Controllers (PLC’s) at each site are primary in the control functions.

Redundancy or fail-over processes exist within the telemetry control system, to allow communication in the event the primary store-and-forward communication system fails.

The system is designed to rely on the most robust components in the system, i.e. PLC’s instead of PC-based software.

Systems providing integrated management of all the technological functions of a building, including access control, security, fire alarms, lights, intelligent lifts and air-conditioning.
As such systems become more common, there is increasing need to connect together controllers made by different companies, something that requires not only a common electrical standard, but also a language, or communication protocol, that all the devices can understand. Today then, not only do the devices need to ensure quality and reliability, but also connectivity with the outside world.

At BENJONO we integrate systems comprising devices made by different manufacturers, all sharing information together.

Reliable and efficient power monitoring and control systems, featuring:

• Consolidated control and distribution of all information from all electrical equipment in a plant regardless of supplier.
• Integration of electrical equipment from different suppliers with different design specifications and functionalities.
• Control in the event of unstable power supply from grid or disruption of power supply in plant that may lead to blackouts and costly, unplanned shutdowns.

Our Substation Automation Systems integrate Intelligent Electronic Devices (IEDs) for protection and control. Combined together the SAS and IED lay the foundation for all the higher-level remote functions such as advanced power system management and the monitoring of the condition of the equipment while it is in service. Station level systems are easy to use and adapt to customer specific requirements. 

Increasing competition is driving many power providers to focus on system productivity, with a view to reducing costs and increasing customer satisfaction, which often involves upgrading aging infrastructure.

Older protection and control systems can be easily upgraded using our modular systems. Updating substation automation offers the opportunity to reduce operational and maintenance costs, increasing plant productivity with the aid of enhanced schemes as well as condition monitoring for circuit breakers, power transformers, etc.
