摘要

Abstract

Based on the standardized cyber-physical modeling and communication system - IEC 61850

this paper establishes the operational control architecture of a low-voltage multi-terminal DC (LV-MTDC) system. The coordinated operational control strategies

including power electronic transformer (PET)

and voltage source converter (VSC)

are proposed. Then a cyber-physical model of the system based on IEC 61850 is built

according to the application requirements of operational control in the LV-MTDC system. On this basis

the implementation method of system operational control based on IEC 61850 is proposed

including the software/hardware design of the intelligent electronic device (IED)

dispatching operations and uninterrupted power supply. The simulation environment is further built to verify the system operational control technology

and the test platform is used to carry out the actual tests. The research results show that the operational control technology for the LV-MTDC system proposed in this paper is feasible

which can guarantee the rapid and accurate information exchange of control commands and settings

and thus effectively realize the operational control of the LV-MTDC system under complex conditions.
