A study of Modifying Bus Impedance Matrix for Node Seperation

노드분할에 대한 모선 임피던스 행열 수정방법 연구

Short Circuit analysis is one of the most fundamental procedures for power system analysis problem. In order 10 solve the problem, In order to solve the problem, it's required to develop an advanced algorithm by which modified bus admittance matrix are easily computed for a large number of alternative network configuration. This paper proposes a new calculation method to efficiently modify the bus impedance matrix elements of large power system by method for removal of link, and presents its Practicality by applying the proposed method in the power system model.
