摘要: |
采用CIM表示法对配电网综合建模,提出一种基于开关类型及状态、DG角色的配电网拓扑岛分解方法。根据配电网设计态结构,静态拓扑分析准备和储存了大量的以双向开关某一端口和DG为功率注入点的拓扑岛子树。动态拓扑分析基于开关状态、DG角色,对各种情况进行逻辑判断,并选择已储存的合适的拓扑岛子树的快速组装形成动态拓扑树,该拓扑结构可直接用于后续潮流计算,满足在线运算的实时性。通过该算法与传统CIM分析的比较,验证了算法的高效性。 |

Abstract: |
Under the comprehensive CIM based modeling, a novel topologic method is presented which divides the distribution network into series of topologic islands according to the types of switches and DGs and their operation states in the networks. According to the structure of design state of the distribution network, the static topologic analysis prepares and stores a lots of sub-trees of topologic islands with their own power supply points in one terminal of bi-directional switches or DG as the main power supply source. Based on the real time states of switches and the role of DG, the dynamic topologic analysis makes the logic reasoning to form a dynamic topologic tree of the distribution networks with the quick assembly of suitable sub-tree of topologic islands which can be directly used for further power flow calculation to meet the real time requirement of on-line mathematic operation. Through the comparison of this algorithm and traditional CIM analysis, this paper verifies the efficiency of the algorithm. |
