Abstract EN
After a faulted transmission line is removed, power flow on it will be transferred to other lines in the network.
If those lines are heavily loaded beforehand, the transferred flow may cause the nonfault overload and the incorrect operation of far-ranging backup relays, which are considered as the key factors leading to cascading trips.
In this paper, a novel algorithm for power flow transferring identification based on wide area measurement system (WAMS) is proposed, through which the possible incorrect tripping of backup relays will be blocked in time.
A new concept of Transferred Flow Characteristic Ratio (TFCR) is presented and is applied to the identification criteria.
Mathematical derivation of TFCR is carried out in detail by utilization of power system short circuit fault modeling.
The feasibility and effectiveness of the proposed algorithm to prevent the malfunction of backup relays are demonstrated by a large number of simulations.
