Examples of Applications

Power Plant Control Systems With Regul PLCs

Automation in power industry includes a number of systems: turbine control, turbine protection, boiler, balance of plant. The capability of Regul RX00 PLCs and, in particular, Regul R600 PLC, to be fast and fault-tolerant, allows system integrators and power plant operators have only one line of controllers for all the systems.

A special stress in development of the controllers we put on the resistance to electromagnetic fields, often abundant in the power plants, and to the support of IEC 60870-5 protocols, namely IEC 101 and IEC 104.

Digital input modules have Sequence of Events capability built-in by default, to analyze events in the system step-by-step without impact of the communication lines. Output modules can be configured for the strategies to properly shutdown the underlying system(s) in case of complete loss of communication.

Extension with the integrated AlfaRegul SCADA brings in redundant servers for operational control, trends, alarms, events, historical data, in-house developed noSQL database optimized for time series. Cascade regulation in the systems is available both at the controller level or through the centralized control from AlfaRegul.
