SCADA: The Heart of Modern Solar and Wind Farm Monitoring

SCADA: The Heart of Modern Solar and Wind Farm Monitoring

SCADA (Supervisory Control And Data Acquisition) is a computer system used for monitoring and controlling technological or production processes. Its main functions include:

  • SCADACollecting real-time data (measurements) from measurement and executive devices such as PLC controllers, I/O modules, sensors, meters, etc.
  • Visualizing data in the form of schematics, charts, tables, alarms, etc.
  • Controlling the process by setting parameters, turning devices on and off, operating the process manually or in emergency mode, etc.
  • Archiving historical data and generating reports.

SCADA is a supervisory system in relation to remote terminal units (RTUs) that collect information about the status of technical devices and transmit it to the central SCADA system. They also accept commands from the central system and act on devices accordingly. SCADA can integrate multiple PLC controllers and support various communication protocols.

Why is SCADA essential for solar and wind farms?

Solar and wind farms are crucial sources of renewable energy that are becoming increasingly popular and profitable. However, to effectively manage and maintain such farms, it is necessary to monitor the areas where they are located and the parameters of the devices. This is precisely what the SCADA system does, providing the following benefits:

  • Improved safety and reliability: SCADA detects and alerts about any abnormalities such as intrusions, fires, equipment damage, exceeding alarm thresholds, etc. This allows for quick response and prevention of greater damage. Additionally, SCADA documents all events and provides evidence in case of insurance claims or legal investigations.
  • Optimization of performance and efficiency: SCADA enables remote control of the energy production process by adjusting device parameters to weather conditions and energy demand. This increases the utilization of installed capacity, reduces losses and operating costs, and improves the quality of energy supplied to the grid.
  • Data collection and analysis: SCADA collects and stores data from the energy production process, such as power, voltage, current, temperature, humidity, wind, insolation, etc. This allows for the creation of statistics, charts, trends, forecasts, energy balances, etc. This data can be used to assess the technical condition of devices, plan maintenance, optimize operating parameters, as well as for reporting and energy production accounting.

How to choose the right SCADA system for a solar or wind farm?

The choice of a SCADA system for a solar or wind farm depends on many factors, such as:

  • SCADA farmy słoneczne i wiatroweScale and type of the farm: Depending on the number and type of devices to be monitored and controlled, the appropriate number and type of RTUs should be selected, as well as the appropriate communication protocol. Additionally, the distance between devices and the SCADA system, as well as the availability and reliability of communication, should be considered.
  • Functionality and flexibility of the system: The SCADA system should be able to meet all user requirements and expectations, such as remote device control and configuration, alarm and notification generation, report and summary creation, integration with other systems such as ERP, CRM, GIS, etc. Additionally, the SCADA system should be user-friendly, scalable, and flexible to adapt to changing needs and conditions.
  • Cost and profitability of the system: The SCADA system is an investment that should pay off within a specified period. Therefore, the costs of purchasing, installing, maintaining, and operating the system should be carefully analyzed and compared with potential benefits.

SCADA is a computer system that forms the heart of modern solar and wind farm monitoring.

With SCADA, it is possible to collect, visualize, control, and archive data from the energy production process. SCADA ensures improvement in the safety, performance, and efficiency of farms, as well as enables data analysis and reporting. The choice of the right SCADA system for a farm depends on various factors such as the scale and type of farm, the functionality and flexibility of the system, and the cost and profitability of the system.
