Abstract

The invention discloses a DC distribution network real-time simulation system and method, comprising: a real-time simulator, a simulation interface device, an I / O consolidation unit, a sub-station control and protection device, a multi-coordinated control and protection device, and a monitoring system device. The real-time simulator comprises a real-time digital simulator RTDS, a gigabit transceiver board GTFPGA and a field programmable gate array FPGA. Through the connection of the above devices, the actual operation conditions of DC distribution network and the precise control and operationcharacteristics of converter and DC transformer are simulated, which provides a simulation platform and simulation method for DC distribution network research.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a real-time simulation system and method for a DC distribution network. Background technique [0002] With the continuous penetration of renewable energy and distributed power, the multiple power supply architecture focusing on distributed renewable energy and microgrid will gradually change the traditional distribution network form, making the future distribution network present a two-way power and intelligent interaction. relation. On the one hand, the DC distribution network can be flexibly connected to distributed power sources and DC loads because of the fast control technology of power electronics, and on the other hand, because it can control the direct closed-loop operation of the distribution network, it has a more efficient structure than the grid structure of the AC distribution network. high reliability. Therefore, both in terms of control flexibility and oper...
