<P>PROBLEM TO BE SOLVED: To provide a method of calculating tidal current for solving tidal current equation, for finding the stationary state of a power system in a short time, without complicating the calculating program. <P>SOLUTION: The tidal current equation can be solved in a short time, by implementing a step S11 for setting a condition for designating a bus bar other than a power generator; a step S12 of constituting a simultaneous equation system, based on the condition for designating each bus bar, designating the equation of a curve for approximating states of a terminal voltage and the reactive power output of the power generator, and combining it with the simultaneous equation system; a step S13 of assuming an initial value of a complex voltage; a step S14 of setting an initial value of a scalar parameter of the equation of the curve; a step S15 of numerically solving the simultaneous equation system by an iterative calculation and finding the complex voltage of each bus bar; and a step S16 of reducing the scalar parameter until a convergence condition for a result of the iterative calculation is satisfied in all power generators. Thus, the result can be obtained in a short period of time on the tidal current equation by processing the steps S15 and S16. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
