新型电力系统中电力电子电源接入容量和占比不断提升,其对继电保护动作性能的不利影响逐渐凸显。全功率型电力电子电源无功补偿能力无法完全等同于同步机电源,会导致距离保护在区内故障时的拒动风险、在区外故障时的误动风险显著增加。为此,文中研究了全功率型电力电子电源接入下比相式距离保护的适用边界。提出了以保护性能要求为约束,以电力电子电源接入容量(作为保护适用边界的评价指标)上限为目标的距离保护适用边界定量计算方法。进一步地,分析了主导保护性能的影响因素,并提出了保护适用边界计算的效率提升方法。最后,大量仿真结果表明,所提方法具有计算精度高、速度快的特点,能够实现距离保护适用边界的准确评估。
With the continuously increasing integration capacity and penetration of power electronic sources in new power systems
their adverse impacts on the operating performance of relay protection have become prominent. The reactive power compensation capability of full-converter power electronic sources cannot be fully equivalent to that of synchronous generators
which significantly raises the risk of failure-to-trip for distance protection under internal faults and maloperation under external faults. To address this issue
this paper investigates the applicable boundary of phase-comparison distance protection with the integration of full-converter power electronic sources. A quantitative calculation method for the applicable boundary of distance protection is proposed
which takes protection performance requirements as constraints and targets the upper limit of the integration capacity of power electronic sources (adopted as the evaluation index for the applicable boundary). Furthermore
the dominant factors affecting protection performance are analyzed
and an efficiency improvement method is put forward for the calculation of the applicable boundary. Finally
extensive simulation results demonstrate that the proposed method features high calculation accuracy and fast computation speed
enabling accurate evaluation of the applicable boundary of distance protection.
