More Information
Summary:The invention discloses a verification method and system for a flexible direct-current power transmission project, and the method comprises the steps: obtaining multiple harmonic voltages generated byan AC system and a flexible DC converter station at a PCC point under different working conditions based on the operation parameters of the PCC point when the AC system is connected to the flexible DC converter station in a flexible DC power transmission project; superposing the same harmonic voltages generated by the AC system and the flexible DC converter station at the PCC point under the sameworking condition to obtain superposed harmonic voltage, and extracting the maximum harmonic voltage of the PCC point under all working conditions; and verifying the performance result of the flexible DC power transmission project based on the relationship between the maximum harmonic voltage of the PCC point under all working conditions and a preset standard. The invention provides a method forchecking whether the perfor
