论文摘要
相量测量单元（PMU）是在传输系统中长期使用的测量设备，如今，对于正确监视分配网格的必不可少。分布式能源资源（DER）的预期大规模渗透正在缓慢地进行，构成了一系列新的挑战，这些挑战用于测试传统工具，并需要更多的性能和灵活性来适应这种不断发展的情况。基于单板计算机（SBC）的廉价设备被证明是传统PMU体系结构的有效替代品，能够将高性能，出色的多功能性和低成本结合在一起。但是，这种设备缺乏对其测量错误的正确建模，相反，这些设备对于改善其设计和根据相关标准评估其性能非常有用。本文打算通过讨论错误源及其对观察到的信号的影响来填补这一空白。提供了误差统计的分析，以提供更完整的计量表征。
Phasor Measurement Units (PMUs) are measurement devices long used in transmission systems and today even more essential for a proper monitoring of distribution grids. The expected massive penetration of distributed energy resources (DERs) is slowly taking place, carrying along a new set of challenges that put to test traditional instruments and requiring more performance and flexibility to adapt to this evolving scenario. Cheap devices based on single board computer (SBC) are proving to be a valid alternative to traditional PMU architectures, able to combine together high-performance, great versatility and low-cost. However, such devices lack a proper modeling of their measurement errors that conversely would be extremely useful for improving their design and evaluate their performance in accordance with the relevant standards. The paper intends to fill this gap by discussing the error sources and their effects on the observed signals. An analysis of error statistics is presented, in order to give a more complete metrological characterization.
