调谐方式对消弧线圈并联运行的影响

随着自动补偿消弧线圈的广泛应用,自动补偿装置的并联运行成为影响配电网安全运行的关键问题之一。本文通过分析消弧线圈并联运行的工作原理和地区配电网的实测数据,讨论了“预调式”和“随调式”自动补偿消弧线圈可能出现的并联运行情况,提出了并联运行需注意的问题及建议的运行方式。优先考虑不同调谐方式的装置并联运行,对已采用预调式消弧线圈的母线并联运行应选择同型号的补偿装置,避免随调式消弧线圈装置的并联运行,并在控制条件允许时,适当采用手动调节方式以改善并联运行方式的灵活性。

Effect of Automatic Tuning Mode Principle on Parallel Operation of Arc-Suppression Coil

With the extensive application of automatic tuning arc-suppression coil,the secure operation of distribution network influenced by the parallel operation of automatic tuning device becomes one of the key problems.By analyzing the principle and the field data of distribution network,the instances of parallel operation under different automatic tuning modes are discussed.The potential problems concerned in parallel operation and the propositional operation modes are presented in this paper.The parallel operation with different automatic tuning devices is recommended as the preferential option.The homotypic device is suggested to be used for the parallel operation with arc-suppression coil under preadjustment mode and the parallel operation with arc-suppression coil under instantaneous adjustment mode is not preferred.The manual mode is suggested to be properly used under certain control conditions to improve the flexibility.
