Abstract

This paper takes a methodical view on the control and security of medium power DC systems in a dynamic appropriation control system considering fault current constraining, system control and converter outline. Lessened terminal capacitance and additional DC impedance are utilized to confine DC fault current and decrease the required converter current rating for medium power DC systems. A versatile DC control stabilizer is proposed to reduce possible system unsteadiness brought by the fault current constraining settings within the sight of constant power load. The impact of the present constraining strategy and the proposed stabilizer on DC fault current and security improvement are approved by simulation with fuzzy logic controller considers utilizing a straight forward two-converter DC circuitry and a multi-terminal DC circuitry in a dynamic conveyance control system and compare the results with PI controller.
