汤阴县奇昌化工公司系专业生产色素炭黑的厂家，色母粒协会成员单位，生产色素炭黑系列产品。 - 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
据此，对该站进行了串联谐振分析和并联谐振分析，并结合测试数据和有关变电站的运行记录，指出了导致该站电容器汤6c频繁烧保险的主要原因是5次谐波电流含量偏高，引起汤7c放电pt爆炸也是因为7次和9次谐波电流被放大。针对这些导致汤阴变电站补偿电容器故障的原因，提出了相应的谐波治理措施，包括针对汤6c电容器5次谐波电流含量偏高的原因，提出了停运汤6c电容器或者通过把汤sc电容器的部分容量并入汤6c电容器(汤sc其余部分停运)以增加汤6c谐波承受能力的措施;针对# 2变低压侧7次和9次谐波电流被放大的现象，提出了在汤7c电容器上加装一定百分比的串联电抗器的措施。 - Tangyin substation is an important substation which has two transformer of 120mva , eight 220kv lines and three 110kv lines . tangqian line is a 110kv line specially for traction transformer substation . because traction load is high - power nonlinear and asymmetry . it will produce much harmonic and negatvie sequence current , which have done harm to compensation capacitors of tangyin substation . in recent years , the tang6c capacitor often interrupted and in 2001 july the tang7c capacitor ' s discharge pt exploded
汤阴变电站是豫北一座枢纽变电站，有2台120mva的主变， 8条220kv线路和3条110kv线路，其中的汤牵线是专为牵引变电站供电的110kv线路。由于电力机车属于大功率的非线性负荷，且三相不对称，在其运行过程中必然会产生较大的高次谐波和负序电流。 - In accord with the state standard about harmonic . the harmonic permission value of tangqian line is calculated . some measurement data are shown and analyzed , and some main conclusion is drawed that the 7th harmonic voltages of tangqian line is near to the permission value , total harmonic voltage distortion ratio has oversteped the permission value . the 3th harmonic , the 5th harmonic , the 7th harmonic and the 9th harmonic current from tangqian line all overstep the permission , the largest 5th harmonic current ratio in tangsc reaches 44 % , the 7th harmonic and the 9th harmonic current in tang7c and tangsc is large maybe because the harmonic current is magnified . this paper studies the model of each element in tang yin substation
根据有关公用电网谐波的国家标准，计算出汤牵线注入汤阴变电站的谐波电流允许值，从实测数据可以得出一些重要结论：汤牵线7次谐波电压含有率的最大值接近国标中的限值，汤牵线的谐波电压总畸变率的最大值已超标；汤牵线注入电网的3 、 5 、 7 、 9次谐波电流都超标；汤6c电容器的5次谐波电流含有率较高，最高达到44 ；汤7c和汤8c电容摘要器的7次和9次谐波电流含有率偏高，原因可能是发生了谐波电流放大现象。 - Because the harmonics in tangyin substation are primarily from electric traction loads , this paper gives the structures of several main locomotive models and general harmonics they produce . the harmonics produced by electric locomotive have a characteristic that their range and phase are both dispersive . this paper also analyzes the impedance - matching balance transformer ' s structure and harmonics injected into the power system at its primary side , and sums up the characteristics of the harmonics from electric traction loads in the tangyin traction substation
鉴于汤阴变电站的谐波主要来自电力牵引负荷，本文列举了电力机车几种主要车型的结构以及它们产生谐波的概况，得出了电力机车的各次谐波电流幅值和相角具有较大分散性的特点。针对汤阴牵引变电站的牵引变压器，分析了阻抗匹配平衡变压器的结构及其高压侧注入电网的谐波，推导了有关计算公式。通过理论分析并结合汤牵线的实测谐波数据，归纳了电力牵引负荷注入汤阴变电站的谐波的特点。
