摘要
针对配电网中台区抗负荷能力较弱,负荷波动恢复时延较长的问题。通过设计负荷交直流检测电路实时检测台区负荷状态,对负荷波动信号及时反应;通过多维分层抽样方法采集负荷波动信号,将波动信号划分条理化;通过改进的错误检测与校正(EDAC)技术,在原有技术的基础上添加特殊寄存器,加强了系统抗负荷波动能力。试验表明,研究的恢复时间分别缩短了0.4 s以下,提高了台区抗负荷干扰能力。
Aiming at the problem of weak anti-load capacity in the middle station area of the distribution network and long recovery time delay for load fluctuation.Real-time detection of the load status of the station area through the design of the load AC/DC detection circuit,and timely response to the load fluctuation signal;the multi-dimensional stratified sampling method was used to collect the load fluctuation signal,and the fluctuation signal was organized and organized;through the improved error detection and correction(EDAC)technology,adding special registers on the basis of the original technology,strengthens the system′s ability to resist load fluctuations.The experiment shows that the recovery time of the study was shortened by 0.4 s or less,which improved the anti-load interference ability of the station area.
