A “new-build” pumping station on the banks of the River Great Ouse in Norfolk. Protecting 1,500 homes, 500 businesses and wildlife (an area of 6,000 hectares) from flooding by engaging 4 pumps capable of moving 16,000 litres per second (1.4 billion litres per day).
Paktronic Engineering were contracted by a major Prime Contractor to design, manufacture and install a bespoke Distribution & Control System to provide full automated and intelligent control of the pumps, knife values, weedscreen cleaner and other ancillary equipment.
The overall Motor Control Centre (MCC) arrangement was built as follows:
Primary Panel (remote) – 6220mm L x 2200mm H x 790mm W
Consisting of 3 sections:
- Generator Incomer, Mains Incomer A and MCC1 Feed
- Fuel Pump Feeder, Spare Feeders, ICA Section and Bus Coupler 3
- MCC2 Feed and Mains Incomer B
MCC (incorporating MCC1 and MCC2) – 16030mm L x 2450mm H x 800mm W
Consisting of 9 sections
- Mains Incomer MCC1 (employing a 2500 amp, 4 pole ACB)
- Pump No. 1 (450kW Inverter and controls) & Knife Valve No. 1
- Pump No. 2 (450kW Inverter and controls) & Knife Valve No.2
- Bus Coupler 1
- ICA, Telemetry, Weedscreen Cleaner Controls
- Bus Coupler 2, Feeders for ancillary equipment
- Mains Incomer MCC2 (employing a 2500 amp, 4 pole ACB)
- Pump No. 3 (450kW Inverter and controls) & Knife Valve No. 3
- Pump No. 4 (450kW Inverter and controls) & Knife Valve No. 4
Employing the latest PLC and HMI technologies our inhouse software engineers created the necessary programing to read all incoming signals from level sensors, health monitors (pump and motor) and run-time to ensure full automation and intelligence protecting both the local environment and the pumping station’s main assets.
Run-time monitoring/recording ensures that when pumping demand is minimal, Duty Pump operation is automatically rotated equally between all pumps. This helps to minimize maintenance and extend the pump/motor life.
