基于双端电气量的串补输电线路故障测距算法
A Fault Location Algorithm for Series Compensated Transmission Lines Based on Two-end Information
摘要
Abstract
The conventional fault location algorithm cannot be directly applied to series compensated transmission lines because of the nonlinear V-A characteristic of metal oxide varistor (MOV) installed with the series capacitor (SC) in parallel. Therefore, based on the Bergeron line model, we deduced the current formula at the one end, using the voltage at the same end and the current at the other end. Applying the formula to the fault location, we presented a fault location algorithm for the series compensated transmission lines. In the proposed algorithm, two-end synchronous voltage and current data were used and the distributed parameter line model in the time domain was applied. The proposed algorithm does not use the model of series compensated device and is not affected by the nonlinear V-A characteristic of MOV in theory. PSCAD and Matlab were used for simulation. The simulation results show that the proposed algorithm has high accuracy, and is not affected by fault types, fault positions and fault resistances.关键词
