Pumps Supervisory Control And Data Acquisition System (SCADA)

Application:

The pumps supervisory control and data acquisition system (SCADA) is intended for the following tasks

• Data collection about current operation parameters and equipment status at the water supply system objects;
• Remote control of equipment in operation;
• Recording and backing-up of the system events, process and equipment parameters.

The system is based on the «HMS Control» series panels implementing a comprehensive management of the water supply facilities:

• Borehole water intakes;
• Water tanks;
• Pumping stations of the second and third lift;
• Measuring points;
• Pressure boosting stations.

The system admits connection to a various supplementary process equipment, valves, etc.

Advantages:

• Reduction of power consumption;
• Reduction of equipment operation costs;
• Reduction of required service personnel number;
• Reduction of response time for emergency situations;
• Increase of efficiency of the water supply objects;
• Increase of intervals between maintenance;
• Real-time access to actual data of the equipment condition with automatic record of system events and back-up;
• Analysis of accumulated data for optimization of equipment operation.

The system operates in the following modes

• Automatic: all the control panels operate with equipment by preset algorithm; the supervisor performs general control and intervenes in the system’s operation, if necessary, in case of abnormal situations, accidents, etc.
• Manual: the supervisor operates with equipment remotely from his automated workstation.

Depending on the objects location and distance between them the following communication ways are applied:

• Wired public or local networks
• GSM / GPRS modem
• 433 MHz radio band

The main elements displayed at the system interface:

• Water supply system objects diagram (can be imposed on the objects’ location map)
• Process scheme of each object
• System events and log of accidents
• Diagrams or tables of the equipment parameters within a period of time

The following data can be displayed on the operator’s automated workstation screen:

• Pressure in pipeline or in the wellhead (for borehole pump)
• Water consumption
• Water levels in tanks
• Temperature of the motor winding or bearings (depending on the pump type)
• Speed of pump shaft (frequency converter is required)
• Electric parameters (e.g. voltage, current)

The operator can perform the following actions from his automated workstation:

• Starting / stopping of the pumping units
• Changing of the pumping units performance (frequency converters are required)
• Control of valves and other processing equipment
• Browsing of the equipment data files, logs and reports for any period (day, month, week, year)
