PURPOSE:To avoid the possibility of the disagreement between a withdrawn switch and a normally-open changeover switch, save operation works and avoid the misinput of informations in a distribution system control system whose processing objects are construction subjects and work subjects. CONSTITUTION:Data items such as a construction date and time, the name of a withdrawn switch, the name of a newly installed switch, etc., which are construction objects, etc., are registered in a construction subject data file. Then work subjects are registered in a work subject data file. At that time, construction subject keywords are also inputted. Then, by refering to the corresponding construction subject with the keyword, the withdrawn switch is picked up and decided to be the normally-open changeover switch. Thus, it is necessary to input the withdrawn switch only and it is not necessary to input the normally- open changeover switch, so that the inputs of the identical informations can be unified. Therefore, the possibility of the disagreement between the withdrawn switch and the normally-open changeover switch can be completely eliminated and a misinput can be completely avoided. |
