摘要
配电网同步相量测量装置可以大幅提升配电网的可测、可观、可控水平,可以解决大规模分布式电源和柔性负荷接入后现代配电网所面临的巨大挑战,促进配电网转型升级。本文提出了基于多级自校验和多重切换的自适应相量算法。在多级校验方面,提出了基于多级自校验识别稳态、动态和暂态3种模式,并设计了适应3种状态的算法。在多重切换方面,提出了通过校验算法、传感器类型、采样率、窗函数类型、数据窗长度和相量算法的多重自切换,以满足同步相量测量装置性能的要求。为进一步验证本文所提算法的优越性能,在仿真软件上进行了仿真测试分析,结果表明所提算法能满足实际应用要求。
With the introduction of phasor measurement unit( PMU),measurable,observable and controllable level of distribution network can be greatly improved. Enormous challenges caused by the penetration of large-scale distributed generation and flexible load in post-modern distribution network can be solved. Distribution network can be promoted. In this paper,an adaptive phasor algorithm based on multi-self-calibration and multi-switching is proposed. Three modes of steady state,dynamic state and transient state are identified using multi-self-calibration,and algorithms adapting to three states are designed. In order to satisfy the requirements brought by the characteristics of PM U,this paper proposes a multi-self-switching method,which includes calibration algorithm,sensor type,sampling rate,window function type,data window length and synchrophasor algorithm. In order to further verify the superiority of the proposed algorithm,simulation analysis is carried out on simulation softw are. The results show that the proposed algorithm can meet the practical application requirements.
