Coherence‐based integrated detection and assessment algorithm for voltages and currents unbalance/disturbance in three‐phase synchronous generators: A validation of simulation results

نویسندگان

چکیده

The phenomenon of imbalance is a variation voltage and current waveforms from perfect sinusoidal waveform, which considered crucial challenge in power systems. Uneven loads disturbances result three-phase voltage/current unbalance that leads to temperature rise low output curves at synchronous machines. Thus, the unbalance/fault must be recognized avoided. This article suggests methodology detect evaluate using coherence algorithm. suggested scheme develops integrated protection functions can divided into three modules: unbalance, factor unbalance. Therefore, it useful mitigation techniques applied compensate effects. present introduces new proposal closed-tripping based on values range nine factors. To investigate performance, segment grid with real parameters’ information simulated utilizing ATP platform. Several fault types, such as shunt series faults, are conducted system analyze results monitor status statistic processed MATLAB software. show approach smart, swift, precise, reliable stable. Moreover, algorithm practically implemented, represents base for digital detectors relays because its performance superior detecting Power Quality Disturbances (PQDs).
