本文对有正交升压变压器（qb）的输电线路的距离保护性能进行了评估。qb在英国输电网中的使用正在增加，以最大限度地利用现有基础设施，并根据运营要求进行快速网络修改。借助实时数字模拟器（RTDS）进行了分析，量化了安装qb并在不同情况下运行的输电线路上可能导致距离保护误动作的误差程度。将来使用qb进行更主动的约束管理可能会导致进一步的复杂性，从而扩展现有保护方案的能力。也考虑了这些问题。此外，定义了自适应中继解决方案的范围，重点是安装了qb的网络的更广泛的保护协调。
This paper presents an assessment of the performance of distance protection for transmission lines in the presence of Quadrature Booster Transformers (QBs). The use of QBs in the UK transmission grid is increasing to maximise the utility of existing infrastructure as well as enabling rapid network modifications as dictated by operational requirements. An analysis is performed with the aid of a real time digital simulator (RTDS) to quantify the extent of error which may lead to the mal-operation of distance protection on transmission lines with QBs installed and operating under different scenarios. Using QBs in the future for more active constraint management may cause further complications that stretch existing protection schemes' capability. These issues are also considered. Furthermore the scope for an adaptive relaying solution is defined with focus on a wider scale coordination of protection for networks with QBs installed.
