After taking the element of adjacent matrix as the function of the state of edges in the network structure, the representation of the element in corresponding adjoint matrix has been given an in-depth analysis. With the use of simplifying method on each element in adjoint matrix, the complete connected matrix could be formed equally with the each element as the set of connected routes. Based on the...
The topology characteristics of the nodal matrix in power system analysis and the adjacent matrix in graph respectively has been proved to be absolutely identical. According to this feature and modification principles of the nodal impedance matrix, a new tracking algorithm for the state change of the circuit breaker has been built based on the general multiplication and general addition operations...
In order to overcome some disadvantages of the conventional adjacent matrix method, the relationship between the elements of the adjacent matrix and the connected routes among nodes is analyzed as the fundamental introduction. Subsequently, the graphic characteristic of the main electrical connection in power plant or substation is extracted as three types: single branch, two branches in-parallel...
With the widely installation of Phasor Measurement Units (PMUs) in power system and the increasing requirement of the real-time monitoring and control, a novel power system topology analysis algorithm is proposed with high precise information from PMUs to improve the performance of current network topology analysis. First of all, a method of identifying switch status is established to correct the...
