<P>PROBLEM TO BE SOLVED: To provide a method for estimating the state of linkage of distributed power supplies, wherein an electrical quantity substituting for a voltage is used for measurement and thus the state of linkage in a distribution system can be estimated with accuracy. <P>SOLUTION: The method is for estimating the state of linkage of distributed power supplies in a power distribution system. A plurality of measuring points 332 to 335 are set in the distribution system. The direction of a current or a current value is measured at each of the measurement points. Then, the adjacent measuring points are compared with each other with respect to the direction of the current or the current value, and thereby the state of linkage of the distributed power supplies G is estimated. <P>COPYRIGHT: (C)2004,JPO |
