一种智能变电站监控信息自动验收系统的研究

随着电力技术的发展,调度监控系统需要在智能变电站中采集大量的设备运行状态信息,导致信息接入验收的工作量非常大。现有的智能变电站监控信息自动验收系统只实现了从终端到主站的信号验收,无法实现整个信号的闭环实时传递。同时,变电站监控中频谱泄漏和栅栏效应会对采集的结果产生较大的影响。对此,基于IEC61850和多机多网并行校核理论,研究并开发了一套智能变电站监控信息的自动闭环验收系统,同时提出了一种基于全相位频谱矫正技术的高效变电站数据监测方法。依托某省电力公司的实际工程项目对提出的理论和方法进行了相关仿真和实验分析,验证了所提出方法的有效性和可行性。

Research on automatic acceptance system of monitoring information in a smart substation

In power technology, the dispatching and monitoring system needs to collect a large number of equipment operational status information from the smart substation. This results in a large amount of work for information access and acceptance. The existing smart substation monitoring information automatic acceptance system only realizes the signal acceptance from the terminal to the main station, and cannot realize the closed-loop real-time transmission of the whole signal. At the same time, spectrum leakage and fence effects in substation monitoring will have a large impact on the results of the acquisition. Based on the IEC 61850 and multi-machine multi-network parallel checking theory, this paper researches an automatic closed-loop acceptance system for the monitoring information of intelligent substations, and at the same time proposes an efficient substation data monitoring method based on full-phase spectrum correction technology. Based on an actual engineering project in the power industry, a relevant simulation and experimental analysis are carried out on the proposed theory and method, and the effectiveness and feasibility of the proposed method is verified.
