Research on Reconstruction Method of Multi-terminal Electromagnetic Loop Networks

Electromagnetic loop networks exist in the process of the power grid development from low voltage levels to high voltage levels. There are some problems in many multi-terminal electromagnetic loop networks, such as the excessive short-circuit current, the uncontrollable power flow and the complex stability control measures. In order to solve these problems, a reconstruction method for the multi-terminal electromagnetic loop network is proposed, which integrates the loop-decoupling technology and the MMC-HVDC. Finally, simulations are carried out in the Urumqi power grid based on PSD-BPA, and the result shows that the method proposed in this paper is effective, the multi-terminal electromagnetic loop network can operate safely after reconstructing.
