With built-in dual channel support, advanced load sharing between machines operating in parallel, rotating diode monitoring, automatic synchronizing, and several integrated communication options, this automatic voltage regulator (AVR) is manufactured using the most advanced microprocessor technology and IGBT semiconductors, allowing current ...

The digital automatic voltage regulator (AVR) uses the same software as the UNITROL 1010 and UNITROL 1020, which prepares it for any demanding grid code requirements as well as a dynamic fault ride through (FRT) detection.

EA63-5 is an automatic voltage regulator (AVR) for AMG synchronous generator industrial application series. The AVR is typically supplied by a single-phase auxiliary winding wound into the stator slots. It also can be supplied by permanent magnet generator ˄PMG˅or phase voltage of main terminal. Table 1: Specifications.

UNITROL 1010 and UNITROL 1020 are automatic voltage regulators (AVR) for synchronous machines of up to 80 MVA. The AVRs can be used for the excitation of indirectly excited synchronous machines and motors. The AVRs can also operate as a reactive power regulators, power factor regulators or field current regulators.

aBB UnitrOL® excitation systems are a key component in many power generating units used by plant owners and operators to achieve reliability of operations, stability, and fast transient response of their assets, as per grid requirements. The UNITROL® 6000 excitation systems series is specifically designed to serve a wide range of applications:

When paralleling, the AVR compensate the input rating and voltage shifting basis on load current, through internal circuit calculation and increase or decrease the voltage.

ABB is the world leading volume supplier of high quality UNITROL automatic voltage regulators (AVR) and static excitation systems (SES) that offers solutions

The exchange of an analog voltage regulator with a UNITROL 1005 was rewarded by excellent performance on reactive load sharing as well as stable regulation. ABB launches a digital automatic voltage regulator (AVR) that targets synchronous machines under 3.5 MVA.
