在有源配电网中引入电流差动保护（CDP）来提高保护的可靠性。然而，adn复杂的故障特性导致CDP性能下降。此外，CDP难以满足各种场景的保护需求。在此背景下，本研究提出了一种基于准功率相空间轨迹的导频保护方法。首先，分析了拟幂定理应用于ADNs的可行性。其次，选取拟功率作为一维时间序列进行相空间重构，分析了内外故障条件下PSTQP的特征；最后，根据不同保护场景的要求，设计了两个保护准则。基于PSCAD/ emtdc的仿真结果验证了所设计的保护准则对各种故障条件的有效性。高速保护方案可以缩短故障持续时间，同步错误免疫保护方案可以减少对数据同步的依赖，不需要额外的同步设备。
Current differential protection (CDP) is introduced into active distribution networks (ADNs) to improve the protection reliability. However, the complex fault characteristics of ADNs lead to degradation of the CDP performance. In addition, it is difficult for CDP to satisfy the requirements of various scenarios for protection. Under this context, this study proposes a pilot protection method based on the phase-space trajectory of quasi-power (PSTQP). First, the feasibility of the quasi-power theorem to be used in ADNs is analyzed. Second, the quasi-power is selected as the one-dimensional time series for phase-space reconstruction, and the characteristics of the PSTQP under internal and external faults are analyzed. Finally, two protection criteria are designed according to the requirements of different protection scenarios. The PSCAD/EMTDC-based simulation results verify that the designed protection criteria are effective for various fault conditions. Furthermore, the high-speed protection scheme can shorten the fault duration, and the protection scheme for immune to synchronization errors can reduce dependence on data synchronization and eliminate the requirement for additional synchronization devices.
