摘要
对柔性直流输电系统能效计量误差进行了分析,指出了影响能效计量误差的关键因素是能效计量器具的精度和误差的一致性;接着从这两个角度对能效计量器具进行了优化,最后通过实验验证了能效计量器具的优化效果,并分析了新器具在计量柔性直流输电系统能效时的误差情况,为柔性直流输电系统能效计量器具的优化提供了参考和依据。
This paper analyzestheenergy efficiency measurement error of the flexible HVDC system,andpoints out that the key factors influencing the energy efficiency measurement error is the precision and the consistency of the error of energy efficiencymeasuring instruments; Then we optimize the energy efficiencymeasuring instrumentsfrom two aspects, finally verifythe optimization effect of measuring instrumentsby experiment,andanalyzethe efficiency measuring error of the new instruments in the flexible HVDC system,which provides reference and basis for the optimization of the energy efficiency measuring instruments of the flexible HVDC system.
