And a solve scheme is presented, controlling the voltage of 220kv power network in chongqing under 232kv during low load period. with the increase of load and power supply, the reasonable positions and capacitance of reactive power compensation become reasonless
隨著負荷的不斷增加，電源亦隨之大幅度增加，使得原網路中本來合理的補償位置、補償容量變得不合理，因此有必要重新選擇補償點。 -
The problem about neutral - point - grounding mode is an all - around technical problem which associated with not only power system reliability ， insulation coordination ， electromagnetic interference ， but assault safety 。 in china ， the neutral grounding modes of the 10kv net involved of none grounding, grounding by arc suppressing coils, resistance grounding or reactance grounding in the past 。 with the development of civic power network ， low resistance grounding mode was used to restrain the over voltage, particularly in guangzhou, shanghai ， beijing ， and zhuhai etc. it was reported that the over - voltage level of low resistance grounding mode is lower than that of arc suppressing coil mode, but the operation carried out the other way 。 at substations in guangzhou and shanghai it was found that the low resistance grounding mode is successful 。 but in some areas ， such as zhuhai ， substations grounding with low resistance revealed some problems ， including power supply reliability rapidly dropping ， transmitting line often tripping ； and person safety being threatened 。 so interiorly the grounding mode selection of the 10kv network was disputed, which mainly focused on the fault form of 10kv net grounding, the apply area of suppressing arcing coil grounding mode, power supply reliability level of the two modes, person safety, communication interfere and the workload of maintenance
爭議點主要是在10kv電網接地故障的形式、消弧線圈接地的應用范圍、兩種運行方式供電可靠性的高低、人身安全、通訊干擾和運行維護工作量等諸多方面。 11 17本論文就是針對以電纜為主的城區10kv電網中性點接地方式的選擇問題進行研究。論文首先對10kv電網的中性點運行各種方式進行分析，比較各方式的特點，然後以重慶儲奇門變電站10kv電網的實際參數來建立數值計算模型，在考慮了電網接地電容電流變化、中性點電阻取值大小、接地點接地電阻值變化等多種影響因素的情況下，對中性點經消弧線圈接地和經小電阻接地方式下電網的過電壓水平和接地點短路電流大小進行了數值計算，其計算結果與電科院所作現場試驗進行了比較。 -
