配电网线路参数和输电网有什么不同
求助 配电网和输电网有哪些区别特别是线路参数?求解 最大区别就是输电网的线 路电阻很小,可以忽略,潮流计算可以采用PQ法,而配电网电阻较大不能忽略,一般采用牛顿法算潮流 最大区别就是输电网的线 路电阻很小,可以忽略,潮流计算可以采用PQ法,而配电网电阻较大不能忽略,一般采用 ...jiangtao 发表于 2011-1-9 14:39 https://tech.cepsc.com/images/common/back.gif
是不是BPA这些软件不能用在配电里啊?
我没查到现在有普遍应用的配电网的潮流计算得软件 Depending on the voltage level. Generally speaking, voltage drop is critical in distribution network but is negligible in transmission network (for short and medium length). For long length transmission line, the power capacity depending on the limit of voltage drop.
The ac resistance of a conductor is Rac = Ploss/|I^2|.Power loss is more in distribution than in transmission networks.
Nowadays, power flow/fault analysis is done using simutlation software (PSSE, Powerworld, etc). The lines are modeled (pie circuit) depending on the length (see any power system book covering load flow analysis). 可以的呀,只有是你选求解时选用牛顿法就行,别用PQ分解法就可以 输电线路R<<X,而配电线路R与X差不多 受教了。 那请问配电网和输电网中潮流各有什么特点和区别呢? 回复 5# jiangtao
BPA可以用于三相不平衡情况下的潮流计算吗? 生生世世生生世世事实
