A pumping station powered by Delta CP2000 frequency drives is delivering efficient irrigation to a dairy farm in South Africa in an area experiencing irregular and ever lowering rainfall.

The dairy farm wanted a pump system to access floor water from wells and guarantee a reliable and cost-effective water supply. The farm’s owner commissioned an appropriate system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for several automation products from Delta.
The deliberate irrigation system comprised two reservoirs at different heights, to be filled with water by a total of six underground well pumps overnight, when the energy prices were low. A transport pump is used to transfer water from the lower reservoir to the upper one. The top difference allows the sprinkler system to be operated using gravity alone in the course of the day, making it significantly efficient. The farm animals and the dairy also can take their water provide from this irrigation system. The key necessities of the project have been cost effectivity and low vitality consumption.

The CP models characteristic a PID controller with suggestions that permits the water level within the tanks and boreholes to be monitored and corrected. This is completed by alternating between the totally different pumps and regularly monitoring the move. If the borehole stage falls below a minimum predetermined by the consumer, the PLC control switches to the following the borehole and prevents the pumps from being damaged.
The system has varied Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water degree above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water stage in the prime reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 collection are used to display all the processes within the system and show system data and warning indicators on a 7 or 15-in contact screen. In-house software additionally allows the time configuration and vitality prices to be monitored remotely. Users can also monitor the whole process via the DOP-100 VNC server.
The system is now working with none points and supplies both livestock and crops with adequate water, even in periods of low rainfall.
