摘要： PROBLEM TO BE SOLVED: To obtain a quadratic programming solving apparatus solving at a high speed a quadratic programming problem. SOLUTION: The quadratic programming solving apparatus comprises: an input means setting the equation of the quadratic programming problem including a function inequality restriction; a conversion means converting the equation into the function equality restriction and a new upper and lower limit restriction for a variable by introducing a slack variable; a correction equation generation means generating a correction equation for obtaining the correction amount of the variable to close to the optimum solution for the quadratic programming problem; a contraction correction equation generation means generating a variable assumed to be on the boundary of the upper and lower limit restriction in the optimum solution from the correction equation and a low-dimensional contraction correction equation obtained by eliminating Lagrangian multiplier for the variable; and a correction amount calculation means obtaining the correction amount of the variable to close to the optimum solution by solving the contraction correction equation. The use of the contraction correction equation obtains an apparatus achieving operation processing-amount reduced high-speed processing in obtaining the optimum solution by repeatedly correcting the variable.

摘要： PROBLEM TO BE SOLVED: To suppress fluctuation in grid frequency by precisely adjusting the output of a generator while optimizing a power generation cost based on an expected value of a total power demand.
SOLUTION: The power controller is provided with a grid monitor which monitors current state of the grid and outputs the amount of power demand, and a generator output optimizer which decides the output of a generator at every specified interval by resolving an evaluation function expression that requires minimum total of power generation cost by considering a demand-supply balance restriction that requires the amount of power demand to be equal to the total of power supply. The generator output optimizer further considers an AFC capacity restriction which is decided based on a speed variation upper limit value of the generator to resolve the evaluation function expression. The evaluation function expression may incorporate a fuel consumption restriction which requires the total output of the objective generator to be equal to a target power consumption amount.

摘要： PROBLEM TO BE SOLVED: To solve the problem that since the retrieval system of a state space is configured to evaluate all states defined so as to be transitable from a "state under consideration", and to repeat the transition of the "state under consideration" to the state having the minimum evaluation function value among those states to discover the optimal solution, the retrieving efficiency is not satisfactory, and the large number of times of retrieval is required. SOLUTION: In a process for evaluating all states defined so as to be transitable from a "state under consideration", the high order M pieces of states whose evaluation function values are satisfactory are extracted (a processing block 5), and some of the changes of the M kinds of states generated due to the transition from the "state under consideration" to the M pieces of states are simultaneously generated with respect to the "state under consideration", and the state having the optimal evaluation function value is extracted (processing block 8), and the transition of the "state under consideration" is carried out (a processing block 9). Thus, it is possible to carry out the transition of the "state under consideration" with a distance 1 or more, and to increase the retrieval efficiency of the state space. COPYRIGHT: (C)2004,JPO

摘要： PURPOSE:To attain rapid processing and to obtain various circuit constitutions in accordance with similarity or a processing speed by finding out a value after the change of an inverted matrix which is caused by the change of a matrix through product circuits, an integrating circuit and a subtractor. CONSTITUTION:The value of CX(s) is calculated by the 1st product circuit 1a and its integrated result is outputted to a point alpha. Then, the CX(s) and X(s) are integrated by the 2nd product circuit 1b and the integrated result is outputted to a point beta. Consequently, the value of integral X(s)CX(s)ds is found out at a point gamma by integrating the said output by an integrating circuit 2 and the value of (A+SC) , i.e. the value X(s) of the inverted matrix corresponding to the matrix obtained after changing its initial value, is calculated by subtracting the value of integral X(s)CX(s)ds at the point delta from the inverted matrix A corresponding to the initial value of the matrix by the subtractor 3a.
