IREG-C©
Compact controller
Compact “all in one” voltage regulator for synchronous machines
The compact version of IREG©
IREG-C© is a compact system for excitation and voltage control of synchronous machines with alternating current and direct current excitation machines.
IREG-C© offers exceptional flexibility and performance in generator applications. The limiting and additional controllers can be extensively configured by the user according to the system requirements.
IREG-C© is equipped with an integrated power unit with IGBT technology
01. Diagnosis
An innovative and full graphic colour touch screen provides access to the necessary control and monitoring functions, as well as the diagnostic and alarm lists.
02. Firmware
The IREG firmware was developed based on the IEEE 421.5 standard and its range of functions is designed to be modular and adaptable. All controllers can be parameterized via a graphical user interface.
03. Engineering
Thanks to the clearly structured functional groups and the innovative commissioning tools, it is easy to adapt or modify the parameters to the plant-specific conditions.
COMFORTABLE OPERATION
Touchscreen components
The integrated touchscreen panel allows you to easily achieve all the functions for visualizing and operating the IREG. The resolution is 800 x 480 pixels and is easy to read.

Functions of the IREG voltage controller
Available functions can be activated or combined via the engineering tool. Thereby it is possible to parameterize a superimposed control (voltage regulator output = current regulator input), resulting in the ability to customize the corresponding IEEE models.

Inputs and outputs of the IREG-C©
The inputs and outputs of the IREG© are grouped on the corresponding I/O cards. The signals of the I/O cards provide them to the processor. The signals of the I/O cards are made available to the processor in an isolated manner. The general input and output functionality is freely programmable. The transducer signals are hardware decoupled and led up in double to each DSP.
The DSP processor provides the actual current, voltage, power factor, active power, reactive power, phase angle, and other measurement values. On different measurement results, a secure system state is entered.
The connection to the field is implemented using industrial connectors.
