PROBLEM TO BE SOLVED: To prepare a platform of safe and high-performance electrical equipment development by mitigating a performance limit of electrical equipment caused by a capacity limit of a distribution panel and adding a communication function.SOLUTION: In a multi-terminal power conversion/distribution device, one end of a plurality of connection terminal groups formed from a power converter comprising a power semiconductor device is connected to a common bus line and the other end is connected with any facility group that supplies/consumes a voltage. Each multi-terminal includes a device capable of measuring various electric amounts of circuits and by performing power control in such a manner that a total sum of power flowing into the common bus line and power to be sent out becomes zero, AC power is communicated from supply facilities to consumption facilities. Further, in a distribution network system, power semiconductor devices are power transistor, thyristor, TRIAC, MOSFET, IGBT, and GTO. 【課題】配電盤の容量制限による電気機器の性能限界を緩和し、通信機能を加えて安全かつ高性能な電気機器開発のプラットフォームを作る。【解決手段】電力用半導体素子からなる電力変換器が構成する複数の接続端子群の片端が共通母線に接続し、もう一端が電圧を供給・消費する設備群のいずれかと接続している多端子型電力変換配電装置において、各多端子が回路の電気諸量を測定できる装置を備え、共通母線に流入する電力と送出する電力の総和がゼロになるよう電力制御を行うことによって、交流電力を供給する設備から消費する設備に融通する。さらに、配電ネットワークシステムにおいて、電力用半導体素子が、パワートランジスタ、サイリスタ、トライアック、ＭＯＳＦＥＴ、ＩＧＢＴ、ＧＴＯである。【選択図】図１
