The configurable iReact-3 controller is a low-cost automation solution, facilitating compensation of reactive loads in power distribution substations. The unit automatically controls reactive load banks, with up to three compensation elements (e.g. capacitors, reactors). The automation is based on intelligent control algorithms, taking into consideration substations’ measured quantities (e.g. reactive power, voltage, active power, etc.), and deciding to attach or detach the compensation elements to the electrical grid. The unit provides all necessary input and output signals and a complete set of functionalities, supporting all application’s requirements, design choices and operation possibilities.

An intuitive, menu driven, configuration of operation parameters, makes the unit easy to use. Several different communication interfaces (such as USB, RS-232, Bluetooth and Ethernet) allow interconnection with host computers, either locally or remotely.

Operations & Features

  • Automates insertion/removal of up to three compensation loads (capacitors/reactors), based on Reactive power and Voltage measurements

  • Validates compensation load attachment/detachment according to reactive power drop/increase and status of termination switches

  • Measures seven analog quantities of the substation (Active power, Reactive power, Voltage, three Leakage Currents, compensated Reactive power)

  • Provides On-Load Tap Changer (OLTC) position, using iReact-TAP family sensors

    Intervenes in OLTC to achieve joint reactive-load compensation and voltage control

  • Supports several different configurable operation modes (Automatic, Time-Schedule, Manual, Logging) and a complex one, using combinations of operational modes

  • Provides Alarm outputs (Capacitor Failure, System Failure) to notify operators for system malfunctions

  • Provides a Remote Bypass Procedure, to allow immediate disengage of unit’s operation by the system supervisor

  • Records system events

  • Records system instances (measurements, statuses, alarms, etc.), in a circular buffer retaining more than one year instances

  • Supports firmware upgrades, either locally or remotely (e.g. via internet)

  • Web server for configuring system parameters

  • Supports Several Communication Protocols
