英文摘要：

Using breadth-first search~ algorithm the structure of distribution network is described. A symbolic dynamics-based simplified operator system for distribution network structure is proposed, and using this operator system the typical structure of distribution network is simplified. Based on the operator system a layered iterative algorithm is put forward and the risks of lines and substations in distribution network are quantized and calculated layer by layer. Calculation results of theoretical example show that the scheme of structure equilibrium is tie optimal one, and results of case calculation show that the risks of lines and substations in complex distribution network can be quantized and analyzed.
