论文摘要
提出了一个能够提供高分辨率连续点(CPOW)和相量测量单元(PMU)测量的数据压缩系统。所提出的技术称为自适应子带压缩(ASBC),将信号空间分配为子带,并根据每个子带的活动带宽自适应压缩子带信号。该提出的技术符合现有的行业相量测量标准,使其适合以连续或爆发的按需/事件触发模式流式传输高分辨率CPOW和PMU数据。关于合成和实际数据的实验表明,ASBC将CPOW抽样率降低了几个数量级,以实时流媒体流,同时保持行业标准所需的精度。
A data compression system capable of providing real-time streaming of high-resolution continuous point-on-wave (CPOW) and phasor measurement unit (PMU) measurements is proposed. Referred to as adaptive subband compression (ASBC), the proposed technique partitions the signal space into subbands and adaptively compresses subband signals based on each subband's active bandwidth. The proposed technique conforms to existing industry phasor measurement standards, making it suitable for streaming high-resolution CPOW and PMU data either in continuous or burst on-demand/event-triggered modes. Experiments on synthetic and real data show that ASBC reduces the CPOW sampling rates by several orders of magnitude for real-time streaming while maintaining the precision required by industry standards.
