| 摘要: |
| 为了减少复杂环网方向保护整定计算中有向简单回路形成的复杂性,对双回线支路进行处理,使得简单回路计算规模得到预先缩小。考察网络实时拓扑分析的动态特性,运用适应型Petri网推理系统拓扑结构,将复杂系统的网络分解为若干基本分析单元,描述了一个由保护开关状态变化引起网络关联节点变迁的离散事件动态过程。通过对电网节点支路关联信息进行推理,得到约简有向简单回路矩阵。通过实际算例仿真,建立模型,分析该方法的拓扑机理,计算结果与传统算法一致,验证所提方法的有效性,得出该方法计算准确、过程简便且易于实现的结论。 |

| Abstract: |
| In order to decrease the complexity of directional simple loop formation in setting calculation of directional protections in multi-loop electric power network,the double loop branches are disposed first to make the calculation scale smaller.Then the whole power network topology is ratiocinated with adaptive Petri net and divided into several analyzing parts according to the dynamic properties of real-time analysis.Discrete events during the dynamic process of node-linkage change induced by a protective switch state change are described.The directional simple loop matrix is achieved by simplifying the association information between nodes and branches.A simulative calculation with the actual data of a real power network is carried out with Petri model built and the topological mechanism analyzed.The result is coincident with the traditional algorithm,which verifies its effectiveness.The proposed method is accurate,simple and easy to be realized. |
