摘要：
A novel wide-area fault location algorithm is proposed. Under the normal condition of the power system, network correlation coefficient matrix is formed. After the fault occurs, by analyzing fault model, value of location function at each search step on each branch is calculated. And fault location is determined on this basis. This method does not modify network matrix during fault location process, and can locate fault branch and fault distance simultaneously. It has less calculation burden and is easy to be realized. The simulation results based on PSCAD verify the validity and feasibility of this method.
