“…Since the secondary current of the CT depends on the difference between the primary current and the magnetising current, a sharp increase in the magnetising current will lead to the deficient secondary current in parts of the waveform where saturation has occurred. This results in an inaccurate measurement of the system current, which can cause a malfunction in protection relays [42].…”

“…Such critical scenario may be interpreted as fault, which leads to mal-operation of various differential protection schemes. As depicted from Figure 15 Further, presence of STATCOM during power swing introduces a biggest threat to the conventional protection scheme [32]. In this context, performance of the proposed detection logic is also tested for such conditions.…”

Conventional transmission line protection algorithms may experience delay or even maloperation in presence of shunt compensation due to various non-fault transient disturbances. This paper presents a time-domain differential protection technique based on Kullback-Leibler divergence with thresholding logic for mid-point static synchronous compensator compensated transmission system. A detection index for each phase currents are computed in order to discrimination the fault and non-fault scenarios. Different structure of power systems modelled using EMTDC/PSCAD are simulated to generate numerous numbers of test cases in order to evaluate the applicability of the proposed differential protection logic. Proposed method is also efficient to differentiate the faults during various non-fault events like capacitor switching, sudden load change, power swing, and current transformer saturation including external fault cases. Results and comparative assessment with recently proposed time-frequency and commercial current differential relaying reports demonstrate the efficacy and robustness of the proposed technique. The results confirmed the accurate operation of the proposed protection technique.
