Abstract
In the presence of nonlinear response created by power electronics-based compensators, reliable fault detection and classification by distance protection relays is a major concern. The unified power flow controller (UPFC) has a dynamic characteristics that causes stability and protection issues. A intrinsic time decomposition (ITD) based strategy is proposed for addressing this issue. A differential energy based detection index computed using ITD and adaptive thresholding technique is employed such that unerring fault detection is achieved wherein faulty phases of a UPFC compensated transmission line are well pointed out. Various fault and non-fault cases considering critical power system conditions are analysed for power systems with varying configurations modelled using EMTDC/PSCAD. A comparison of the current detection method to recently proposed techniques reveals the benefits and feasibility of the presented detection strategy, which has been proved to be accurate and efficient.
Highlights
– Unit protection of UPFC-compensated lines irrespective of compensation mode and level.
– Intrinsic Time Decomposition based detection index using current signal to detect faults.
– Accurate identification and discrimination of fault and non-fault events.
– Adaptive threshold technique immune to power system structure.
The executional burden time is near about 5 ms.
