電力系統シミュレーション技術の変遷と今後の動向

抄録

This paper describes historical trends of electric power system simulation technology. The first paper concerning power system simulation study was published in 1916, sixteen years later after the year 1900 when a practical high voltage three-phase ac power transmission line was constructed and put into operation in USA. Historical trends of power system simulation technology can be divided into three stages from the viewpoint of epoch-making progress. The first stage is to simulate the power system behaviors by using a miniature power system circuit called as artificial transmission line. The second stage started from simulations of transient behaviors by the differential analyzer which enables to simulate transient behaviors by calculating mathematical representation model without using miniature machines and circuits. Many simulation tools were developed for calculating the transient and dynamic behaviors by mathematical models. The third stage is the digital simulation technology. This paper introduces the developed simulation technologies and describes the background and needs of the developed technology, furthermore observes on simulation technologies to be developed in the future from the viewpoint of historical trends of simulation technology.
