AUTOMATED CONTROL SYSTEM FOR PUMPING STATIONS – Dimitrovgrad
The water supply infrastructure in Dimitrovgrad has been significantly modernized through the implementation of a state-of-the-art automated control system for three key pumping stations – PS No.1 “Chernokonevo”, PS No.2 “Marijno”, and PS No.3 “Iztok”. The project was successfully delivered by Rotec Ltd., a trusted Bulgarian integrator specializing in industrial automation solutions. The system is designed to enable full remote monitoring and control through a comprehensive SCADA system.
Reliable Control with Allen Bradley PLCs
Each pumping station operates with its own Local Control System (LCS) built around the Allen Bradley MicroLogix 1400 programmable logic controller (PLC). These robust controllers provide reliable automated operation, including control of pumps and integration with all instrumentation and measurement devices. In automatic mode, the stations are fully controlled by the PLC without requiring any operator intervention.
Flexible Operation Modes
The system supports multiple modes of operation—Automatic, Remote Manual, and Local Manual—providing flexibility for operators and quick response in emergency situations. Control mode selectors installed on each station’s panel allow switching between remote and local control, ensuring that the operation can continue under various conditions, including communication loss or maintenance procedures.
Seamless Remote Communication via Prosoft GSM Modems
To ensure reliable remote access and communication between the pumping stations and the central dispatch center, the system utilizes GSM modems by Prosoft Technology (RLXIC-EH). These modems, along with VPN-secured data transmission, support robust two-way communication, enabling operators to monitor all processes in real time, including pump activity, alerts, and measured parameters like flow rate, pressure, and power consumption.
Comprehensive Visualization with SCADA
The implemented SCADA system provides graphical real-time visualization of all key technological parameters across the three pumping stations. Operators receive clear status indicators for each pump (running, stopped, alarm), along with real-time data on level, flow rate, pressure, power usage, and more. Alarm and diagnostic messages are displayed in Bulgarian for ease of use.
Conclusion
By leveraging high-quality solutions from Allen Bradley and Prosoft Technology, and through expert integration by Rotec Ltd., Dimitrovgrad’s water supply infrastructure now benefits from modern, reliable, and intelligent control. This project serves as a benchmark for automation in municipal and industrial utility systems across the region.
