The ABB REF615 HCFKAEADABCZDAA11E feeder protection and control device realizes protection, measurement, control, recording and intelligent networking functions of medium-voltage conventional feeders based on core mechanisms of high-speed digital sampling + standardized multi-logic intelligent fault judgment + graded protection linkage + real-time data interaction + full-sequence event traceability.
After power-on, the device automatically completes full hardware self-inspection, sampling calibration, communication initialization, protection parameter loading and station-wide time synchronization, and enters real-time monitoring standby status after passing self-check. Analog signals from VT/CT secondary circuits are converted into standardized digital data via high-speed AD conversion. The core processor analyzes electrical amplitude, phase, frequency, load trend and sequence component characteristics in real time, and synchronously collects binary signals such as breaker position, local/remote status and equipment alarm to complete full-dimensional real-time monitoring of power distribution circuits.
Under normal grid operation, the device continuously performs high-precision electrical measurement, load statistics, status monitoring and real-time data upload, maintaining stable two-way data interaction with upper monitoring and dispatch platforms. When feeders encounter short circuit, grounding, overload, voltage/frequency abnormality, equipment failure and other abnormal conditions, the device quickly compares real-time sampling data with preset protection settings and thresholds to accurately judge fault type, area and level. It outputs tripping signals according to tuned time limit and interlock logic to isolate faulty circuits instantly, meanwhile locking fault data, recording full-process waveforms and sequences, and actively uploading fault alarm information.
The device supports local manual operation and remote background telecontrol for parameter modification, setting tuning, switching control, program upgrade and loop verification. Full hardware self-diagnosis is enabled during operation, actively alarming and locking abnormal logic for hidden dangers such as sampling abnormality, communication interruption, power failure and hardware defects, fully ensuring safe, stable, reliable and intelligent operation of conventional power distribution systems.
