智能牵引变电站建设方案研究

Research on the construction scheme of smart traction substation

智能变电站在电力行业已逐步推广,而作为电气化铁路关键环节的牵引变电站在智能化方面尚未真正起步。针对智能牵引变电站研究及应用还比较滞后的问题,介绍了电气化铁路牵引变电站自动化系统现状及其存在的问题,分析了比传统变电站技术水平更先进的数字化变电站的优势及其局限性,对比了智能化变电站和数字化变电站的不同点;参考电力行业相关规范和标准,结合电气化铁路牵引变电站的特点,构建了智能牵引变电站的总体架构,给出了智能牵引变电站的网络结构及站控层、间隔层、过程层等各层的具体配置方案,提出了适合牵引变电站牵引变压器、断路器及高压组合电器等一次设备的智能化方案。该研究成果对开展智能牵引变电站理论及应用研究具有一定的参考价值。

Smart substation has been gradually extended in the power industry, but the intellectualization of the traction substation which is the key link of the electric railway has not been really started. Aiming that the problems that research and application of the smart traction substation is still relatively backward, the status and problems of the traction substation automation system was introduced. The advantages and limitations of the digital substation which is more advanced than traditional substation was analyzed. The differences between smart substation and digital substation were compared. Referred to the relevant power industry norms and standards, combined with the characteristics of the traction substation, the overall architecture of the smart traction substation was constructed. The network structure and the configuration programs of the substation layer, bay layer and process layer of the smart traction substation were given. The intelligent primary equipment scheme suitable for traction substation was proposed such as traction transformer, circuit breaker, gas insulated switchgear, etc.. The results have certain reference value to carry out theoretical and applied research in the smart traction substation.
