摘要
达拉特发电厂220KV升压站是内蒙古电网的枢纽变电站,该变电站的铁磁谐振问题严重影响电网安全,研究、解决铁磁谐振问题具有重要的理论意义和实用价值。铁磁谐振问题影响因素很多,很难找到理论上、实际上的最优解决办法,本文提出电压互感器一次侧中性点瞬时接入电阻的方法。
从达拉特发电厂实际出发对历次铁磁谐振进行了研究,阐述了断路器断口均压电容引起的铁磁谐振现象,分析了产生的原因,用数值仿真、实测等方法分析了断口均压电容、母线对地电容、铁磁元件、元件动态磁滞特性对铁磁谐振的影响。讨论了铁磁振谐的限制措施,并对各种措施进行了比较,提出了有效限制措施。对所提出的新方法进行了现场实测,取得了较为满意的结果,验证了本文所提出的消谐方法是正确而有效的。
The 220KV step-up substation of Darat power plant is a central transformer substation in Inner Mongolia Power Grid, The ferroresonance problems in the substation seriously affect the network security, Studing and resovling the ferroresonance problem have important theoretical significances and practical values. There are many factors that effect the ferroresonance problem, it is difficult to find the optimal solution in both theory and actual application, in this paper, a method that instantaneously access a resistance at the primary side side of the voltage transformer neutral point is put forward.
Based on Darat power plants actual situations the several ferroresonance problems are studied, ferroresonance phenomenon caused by the pressure capacitor at circuit breaker fracture is described, the cause is analyzed, numerical simulation and experimental methods are use to anlyze the effects of fracture pressure capacitance, bus-to-ground capacitance, ferromagnetic components and component dynamic hysteresis characteristics on ferroresonanc.Measures for restricting ferroresonance are discussed, and various measures are compared, finally the effective restrictive measures is proposed.The on-site field measurement for the proposed new method has got a more satisfactory result, which validate that the proposed harmonic elimination method is correct and effective.
