IREG^©

IREG^© is a compact, modular designed system for excitation and voltage control of synchronous machines. It also uses alternating and direct current exciters for static systems.

IREG^© provides a wide performance and flexibility for motor- and generator applications. Limitation and additional control functions can easily be designed and implemented by the operator, according to the specific plant capabilities.

IREG^© is connected to a power stage called “IREG-power” in the basic version. The implemented CAN-Bus topology allows the operation of up to 3 IREG voltage regulators and 3 IREG-power modules simultaneously. Hot-Standby, redundancy and TMR (Triple Modular Redundancy) can be implemented easily, according to the needs of the mission-critical plant processes.

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 synchronization feature is carried out directly by the DSP’s, where one processor executes the synchronization task and the other one the synchro-check function.

The connection to the field is implemented using industrial connectors.
