一起变电站消弧线圈大容量改造方案分析

摘要

Analysis on frequent 10kV single-phase ground phenomenon sent in error by 220kV dual-gate substation finds out that the lack of substation capacity petersen coil, results in under compensation operation. A technical analysis is conducted to calculate the deficient amount of petersen coil capacity and select the optimal transformation scheme, providing an economic and safe option for transitional transformation of petersen coil capacity for old substations.%对220kV双闸变电站长期误发10kV单相接地现象进行分析，发现了变电站消弧线圈容量不足，造成长期欠补偿运行的现象。对此进行了技术分析，计算出消弧线圈容量的缺少量并选择最优的改造方案，为老旧变电站的消弧线圈容量过渡性改造提供了经济安全的选择。
