Abstract

The structure and relay protection configuration of large-scale phase modulator system in HVDC converter station are introduced. Considering the hazards of long-term incomplete phase operation of synchronous condenser

a field test method for incomplete phase operation of the synchronous condenser is proposed in view of the configuration defects of the incomplete phase protection. The characteristics of incomplete phase operation are analyzed through the analysis of test fault recording data. Finally

a three-level protection system solution of incomplete phase protection

synchronous condenser protection and grid-connected switch failure protection is proposed.
