電抗電路-
The way of taking one nth out of capacitor ' s the first harmonic capacitive reactance as its nth harmonic impedance is verified whit the data from tang7c. according to the approximately estimating method, the first harmonic impedance of 220kv system is calculated. on the basis of the models, this paper gives the harmonic equivalent circuit of substation and gives the b ( n ) function of the harmonic time n. when the capacitors has different combination, b ( n ) ' s value will also change, with the inputting local measurement data, the paper studies the series and parallel resonance at the substation, and deduces that the reason the capacitor ' s fuse of tang6c is frequently interrupted is that its capacitor current contains a large number of 5th harmonics, and that the reason the discharging pt of tang7c capacitor being exploded is also that the 7th and 9th harmonic currents are amplified
據此，對該站進行了串聯諧振分析和並聯諧振分析，並結合測試數據和有關變電站的運行記錄，指出了導致該站電容器湯6c頻繁燒保險的主要原因是5次諧波電流含量偏高，引起湯7c放電pt爆炸也是因為7次和9次諧波電流被放大。針對這些導致湯陰變電站補償電容器故障的原因，提出了相應的諧波治理措施，包括針對湯6c電容器5次諧波電流含量偏高的原因，提出了停運湯6c電容器或者通過把湯sc電容器的部分容量併入湯6c電容器（湯sc其餘部分停運）以增加湯6c諧波承受能力的措施;針對# 2變低壓側7次和9次諧波電流被放大的現象，提出了在湯7c電容器上加裝一定百分比的串聯電抗器的措施。 -
