Two of the important requirements are increasability and the maintenability of the software system due to the increase of the power systems’apparatus. Some of other requirements are the multipurpose useages of large data from wide service area, and that the power systems’control be highly reliable. The software structure must be constructed comprehensible for engineers of design and maintenance who are usually specialists for power systems’control, but not for computer programming. So,we developed a computer software designing technique which enabled easy maintenance and is highy-reliable. The technique has been put to practical use in some power systems’control fields. In this paper, we argue the necessity of hierarchical decomposition of the software system for the power systems’ control, and propose a method of hierarchical software decomposition which realizes it easy to document, to coodinate, to maintain the software system and to pursue high-reliability, by qualitative studies of the concept of hierarchy and program models.}, pages = {171--179}, title = {電力系統制御用ソフトウェアの階層化分割法について* -階層化分割法の定性的検討-}, volume = {9}, year = {1978} }
