いる。In the system simulation part of the power system operation training simulator, the voltage value is calculated. The calculation of this voltage value is performed by solving a linear algebraic equation based on the coefficient matrix determined by the connection state of the power system. When creating a coefficient matrix, after the matrix elements are calculated, triangulation decomposition is performed to decompose into an upper triangular matrix and a lower triangular matrix.
Usually, it takes time to perform this triangulation decomposition. Creation of the coefficient matrix and its triangulation decomposition must be performed when the connection state of the power system changes. During the training, a simulation of the occurrence / clearance of an accident and the accompanying simulation of various relays such as main protection and backup protection relays are performed. When an accident occurs, the main protection relay and the backup protection relay operate within a few hundred milliseconds to protect the power system from the accident.
In addition, an undervoltage relay, a frequency relay, or the like operates depending on the situation of voltage drop or frequency fluctuation. In addition, the reclosing relay may operate when the accident is released. When these relays operate, transmission lines and transformers are cut off or connected. As described above, the connection state of the electric power system is frequently changed for several seconds after the occurrence of the accident, and therefore it is necessary to repeatedly create the coefficient matrix and triangulate it. For this reason, it took time to simulate the response of the power system for several seconds after the accident, and it was sometimes impossible to maintain real-time performance. However, actually, when the connection state of the power system is changed, it is not necessary to recalculate all the elements after the triangulation decomposition of the coefficient matrix, and only the part related to the change of the connection state may be recalculated. The present invention has been made to solve the above-mentioned problems, and when the connection state of the power system is changed, it is not necessary to recalculate all the elements of the coefficient matrix as in the conventional case, but is related to the change of the connection state. The purpose of the present invention is to provide a power system operation training simulator that speeds up calculation by recalculating the values of only the elements to be operated and secures real-time performance.

The coefficient matrix creation / modification switching means determines whether to activate the conventional coefficient matrix creation means or the coefficient matrix modification means according to the change amount when the connection state of the power system is changed due to an accident or the like. Is a means to do. The coefficient matrix correcting means is means for recalculating the values after the triangulation decomposition of the elements related to the change of the connection state.

The coefficient matrix correction means stores this result in the simulator data storage area, and then activates the voltage calculation means. According to the coefficient matrix correction means, not all elements are triangulated and recalculated, but only the elements related to the change in the connection state are recalculated. Therefore, recalculation of elements after triangulation decomposition is performed faster than in the past. Be done. The voltage calculation means extracts the value after the triangulation decomposition of the coefficient matrix in the simulator data storage area and calculates the voltage value.
