To assess the loss of flexible HVDC system of each device and overall system. An energy efficiency measurement scheme for flexible HVDC system is proposed in this paper. In this scheme, the selection of revelant energy efficiency measurement point is determined by analysing the loss of each energy consumption equipment in flexible HVDC system combined with energy consumption rate, economy, harmonic influence and so on. Moreover, the accuracy of measuring device is analyzed according to the error transfer theory. This scheme provides reference for the energy efficiency analysis of flexible HVDC system.
