智能变电站变压器保护系统可靠性研究

Reliability Analysis of Transformer Protection System in Smart Substation

从研究智能变电站变压器保护系统可靠性的角度,结合智能变电站的特点,利用相应的变压器保护系统模型,借助可靠性分析和组网方式研究进行了讨论。分析结果表明,直采直跳模式的可靠性最高,不需要用到交换机设备就可以直接对报文进行传输,传输效率大大提高,而且不会对跳闸的速动性产生任何影响。

From the perspective of studying the reliability of the transformer protection system of intelligent substations,it is discussed with the help of reliability analysis and networking mode research by combining the characteristics of functional substations and using the corresponding transformer protection system model.The analysis results show that the direct harvesting and direct hopping mode has the highest reliability and can directly transmit the messages without using switch equipment,which greatly improves the transmission efficiency and does not have any effect on the quick-action of tripping.
