摘　　要：针对±800 kV天中直流工程投运后,河南电网逐步向受端电网转变,进入交直流混合运行状态,从受端电网安全稳定性来开展±800 kV天中直流工程运行故障及风险因素的分析。After the±800 kV Tianzhong DC project is put into operation,the Henan power grid gradually shifts to the receiving-end power grid and enter the AC-DC hybrid operation state.The analysis of operation faults and risk factors of±800 kV Tianzhong DC project is carried out based on the safety and stability of the receiving-end power grid.
