Reactive Power Controllers

Reactive power controls, represented by the ERG series, are designed to address a wide range of compensation requirements. These solutions cover three-phase or single-phase systems, medium or low voltage applications, balanced or unbalanced loads, and both normal and fast changing loads, including those requiring thyristor-controlled reactors. The ERG-1800C, a model in this family with 18 contacts, supports power factor correction using detuned reactors, single-phase and three-phase capacitors. Furthermore, it incorporates Modbus communication feature for enhanced functionality.

Power factor management refers to the monitoring and control of microprocessor-based electronic devices used in central compensation systems to automatically adjust groups of capacitors based on the target power factor. These devices are used to improve power factor, increase energy efficiency, minimise energy losses and prevent reactive power charges by balancing reactive power within the system. By activating or deactivating capacitors according to the desired power factor, they ensure optimum system performance, increase stability and extend the service life of electrical equipment.

Stepped reactive power control constitutes an alternative approach to the management of reactive power. These devices, which are typically microprocessor-controlled, operate in accordance with predefined setpoints, with a view to enhancing energy efficiency and ensuring system safety. These devices are designed to continuously monitor the real-time power factor and reactive power requirements within the system. In instances where the power factor dips below the predetermined threshold, the device methodically engages capacitor banks. Conversely, if the power factor exceeds the target level, the device deactivates the banks. This process enables real-time compensation of reactive power demand, thereby maintaining the power factor at the desired target level.

The characteristics of  reactive power controllers include:

• Real-time monitoring of current, voltage, active power, reactive power, apparent power, power factor, Cos φ, and other parameters on the main screen.
• Large display screen
• Remote access and the ability to adjust settings via modem.
• Viewing of parameters like power and switching counts of individual steps
• Vectorial display of the phase angle between current and voltage
• User guidance during system setup
• A recommendation screen to help update the system
• Compatibility with single-phase and three-phase capacitive and inductive loads

Reactive power controllers offer numerous benefits, including enhancing energy efficiency, lowering costs, and ensuring system reliability. The advantages of reactive power controllers can be summarized as follows:

• The reactive power controller is equipped with a user-friendly interface and display, facilitating straightforward operation and configuration. The large and clear display presents all essential information and setting options, enhancing the user experience.
• The device incorporates a pragmatic setting wizard. This feature enables users to input system and step number information expeditiously and efficiently. The wizard’s simplified approach to system configuration is designed to reduce the time and effort required from the user, thereby enhancing operational efficiency.
• The reactive power controller incorporates a feature that facilitates swift and straightforward identification of the system following connection. The user can have the device automatically detect and recognise all connections by simply pressing a single button. This feature simplifies the installation process and reduces the risk of human error.
• The device has the capacity to alternate between steps in a balanced manner by operating in co-aging mode, thereby ensuring the uniform utilisation of the capacitor banks and extending the lifespan of the devices. This balanced switching of steps contributes to the efficient and reliable operation of the system.
• The reactive power controller is equipped with a display that provides the user with information regarding changes and improvements that are required for the system. This display offers the necessary data to enhance energy efficiency and optimise system performance.
• The reactive power controller displays the inductive and capacitive ratios of the system at various time periods (daily, hourly, weekly, monthly) on the main screen, allowing the user to monitor and analyse the performance of the system and make necessary adjustments
• The reactive power controller also provides graphical monitoring of harmonics in the system up to the 63rd harmonic value, making it easy to detect harmonic distortions in the system and take corrective measures.
• The reactive power controller has been engineered to facilitate the connection of both single-phase and three-phase capacitive and inductive loads. This design affords enhanced flexibility, enabling precise system configuration and the management of diverse load types.
• The integrated modem facilitates remote access and configuration changes via an internet connection, thereby enabling users to access, adjust settings and monitor the system remotely. This feature not only streamlines maintenance and management processes but also significantly reduces time requirements.
