PURPOSE:To improve the system stability discriminating accuracy of the title device and, at the same time, to enable the device to present a guide to the operator of a system for controlling the stabilization of the system by constituting a hierarchical neural network by inputting synchronizing torque coefficients and indicating the constituted result to the operator. CONSTITUTION:The power flow data 11 of a subject system are inputted to a synchronizing torque coefficient calculating section 1 and a synchronizing torque coefficient Kij is calculated on the basis of the data 11. The coefficient Kij is defined by the number of nXn when the number of generator models constituting a power system is (n). In other words, the coefficient Kij is a real number expressed by a nXn-dimensional matrix element. The calculated coefficient Kij is used as the input data of a hierarchical neural network section 2 and the output data of the section 2 are results 13 of stability discrimination. The coefficient Kij is also inputted to a result displaying section 3 for giving a guide to the operator of the system for controlling the stability of the system. |
