Analysis of the Impact of Relay Protection in AC/DC Hybrid Power Grid Based on PSCAD
Along with the expansion of the scale of the new power electronics equipment, the new energy is transferred through the UHV. The mixed operation of AC and DC in the power grid poses a challenge to traditional relay protection due to the complex and variable characteristics of the power grid. Based on simulation data, the interaction effects of AC/DC relay protection under various DC output modes were studied. Through simulation data, the AC electric properties of AC/DC hybrid power system and the operation performance of typical AC protective devices were analyzed.
