摘要： PURPOSE:To approximate the initial value of coupling weight calculated from assumed sampling data to a final value and to attain rapid learning reducing repeated operation by obtaining an output corresponding to an inputted learning data at the time of inputting the learning data. CONSTITUTION:In a device constituted of an input layer 11a, an intermediate layer 11b and an output layer 11c and provided with plural nerve elements 11 simulating nerve cells in an organism and coupling weight for coupling between nerve element layers, sampling data constituted of a pair of an input value obtained at a fixed interval and an output value corresponding to the input value are assumed against learning data constituted of a pair of an input value obtained at an irregular interval and an output value corresponding to the input value.

摘要： PURPOSE:To speed up learning and to predetermine the number of neural elements in an intermediate layer by storing a sampling function which is moved in parallel by input values in the neural elements in the intermediate layer, setting an output value as coupling weight, and adjusting the output value. CONSTITUTION:The neural network device assumes sampled data obtained by sampling learning data consisting of the input values x1, x2, and x3 obtained at irregular intervals and the output value (y) at constant intervals. The sam pling function which is moved in parallel by the input values of the sampled data are stored in the neural elements 11 in the intermediate layer 11b and the output value (y) of the sampled data is set to the coupling weight 12 between an input layer and an output layer. The coupling weight 12 which is the output value of the sampled data is so adjusted that a desired output value is outputted by the neural network device when the input values of the learning data are supplied to the neural network device.

摘要： PURPOSE:To obtain a desired output fast by storing a sampling function which is moved in parallel by input values of learning data in neural elements in an intermediate layer and setting the output value of the learning data as coupling weight for coupling the intermediate layer with an output layer. CONSTITUTION:The neural network device stores the sampling function which is moved in center in parallel by regularly obtained input values x1, x2, and x3 in the neural elements 11 in the intermediate layer 11b. For learning data consisting of pairs of the input values and output value (y) as to the respective pairs. The output value of the learning data is assigned as the coupling weight 12 between the intermediate layer 11b and output layer 11e. For example, when repetitive arithmetic need not be performed as learning and an optional input value of the learning data is supplied to the neural network device, the desired learnt output value is obtained, so the calculation time can be shortened since the execution time accompanying the learning includes no repetitive arithmetic.

摘要： PURPOSE:To identify the cause of an abnormality as well as the information whether normal or abnormal by providing a neural circuit network device identifying the cause of the abnormality in the case an unknown sensor output is input. CONSTITUTION:If a foreign material 5 comes in and partial discharge 6 is caused, internal insulation gas is vibrated and the vibration propagates to a tank 2. As a result, the tank 2 mechanically vibrates and the vibration is obtained as acceleration change in an accelaration sensor 7 output. A calculator 8 converts it to a spectrum with an FFT and a calculator 9 time-averages it. A calculator 10 normalizes the magnitude and inputs in a neural circuit network device 11. As in the neural circuit network device 11, the relation between the abnormality cause and the spectrum memorized as learned data is stored as each combining weight 19, a neural element corresponding to the abnormality cause outputs a large power based on the memory when an unknown spectrum of the acceleration sensor is input. As the result, not only abnormal or normal is identified but also the generation of the abnormal state corresponding to the label according to the output layer 18b of the neural element which is generated in an electric appliance such as gas insulation breaker, is identified.

摘要： PURPOSE:To obtain an answer of an optimization problem regardless of some troubles of the nerve simulation elements and the connection elements by allocating the approximately same working states to the problems to be solved by the nerve simulation element groups for multiplexing and also multiplexing the connection element groups which feed back the output signals of the nerve simulation elements. CONSTITUTION:Each nerve simulation element contained in the nerve simulation element groups 11 has a nerve simulation circuit network 1 which calculates the sum total of the feedback signals received via each connection element 21 and the independent signals 31 approximately equal to each other and inputted separately from those feedback signals and at the same time secures locally a minimum energy state for an aggregate. Furthermore, a computer 3 is added to perform the transfer of information to the network 1. Thus it is possible to obtain an answer of a combined optimization problem in a stable way regardless of some troubles of the nerve simulation elements and the connection elements.

Subsequently, based on the reactive power load flow jQJI and its desired value Q*MJI, a reactive power request-value QARI of the controlled power system 1 is computed in a reactive power request-value computing portion 13. Then, in a control-apparatus command portion 14, controlled system apparatuses are selected and controlled to respond to the reactive power request-value QARI.
