Features
• Manual control of field voltage, field current or start angle of the power module;
• Automatic control of armature voltage;
• Adjustable droop for parallel operation (reactive compensation);
• Negative droop for line fall compensation;
• Power factor control;
• Reactive power control;
• Power system stabilizer – PSS (optional);
• Automatic priming in start, being able to be reapplied during normal operation if the voltage falls below the setpoint value;
• Possibility of double channel operation;
• Option of operating with power module incorporated or separate;
• Clock with possibility of synchronism with GPS system by means of signal IRIG-B;
• Record of digital events, recorded in memory card of type SD;
• Record of oscillographies, recorded in memory card of type SD;
• Rise/fall ramp adjustable for all control references;
• Synchronizer – allows adjusting the voltage, frequency and phase of the generator
for synchronism with bar (optional);
• Software for parameterization with friendly interface allowing executing
adjustment, programming and monitoring of all the functions of the regulator;
• Function of reference follower between regulators in the double channel topology or between operation modes in the single channel topology, so that the transfers between channels or between operation modes in the same regulator occur smoothly;
• Programable logic, allowing configuring the function of digital and analog inputs/output, creating internal logical functions, using logical ports, timers, latch, etc.;
• Distribution of reactive power between machines;
• Detection of failure of rotating diode (optional);
• Control “zeroes reactive” to allow opening of circuit breaker with minimum
current of armature.
