一种用于柔性直流输电系统的能效计量方案

为评估柔性直流输电系统各能耗设备及整体系统的损耗,提出一种用于柔性直流输电系统的能效计量方案,该方案通过对柔性直流输电系统各个设备损耗的理论计算,结合能耗率、经济性、谐波影响等因素,确定了相关能效计量点的选择。同时,根据误差传递理论分析了计量装置的准确度等级要求。本方案对柔性直流输电系统的能效计量分析可起到借鉴作用。...

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