| 摘要: |
| 基于人机界面的PSS/E单步潮流计算存在模型维护工作量大和扩展性较差的问题。提出了一种基于CIM/E全模型的扩展PSS/E潮流计算方法。以网络层次模型库为中间层，将CIM/E模型解析到中间层数据库并生成实时同步的PSS/E计算库，实现电网全物理模型的自动建模。基于API接口二次开发和封装，建立接口层，通过外部程序对PSS/E进行流程控制，实现潮流计算的自动周期运行。以层次库为输入输出接口，接收处理外部应用的设备操作指令，实现设备操作的自动交互。基于层次库实时拓扑分析，对PSS/E全模型仿真中的拓扑问题进行修正，保证了拓扑分析的正确性。使用华东电网实际电网模型进行实际应用，仿真结果证明了该方法的正确性和实用性。 |

| Abstract: |
| The single step power flow calculation of PSS/E based on man-machine interface have problems such as heavy workload in model maintenance and poor scalability. An extensible PSS/E power flow calculation method based on CIM/E full model is proposed. By using hierarchical network model database as interlayer, CIM/E model is parsed into the interlayer database and the synchronized PSS/E calculation database is generated simultaneously, and full physical model of power grid is built automatically. Interface layer is built based on API secondary development and packaging, and power flow calculation is run automatically and periodically by flow control of PSS/E through external application. By using hierarchical network model database as input and output interface to receive and process device operational order from external application, interaction of device operation is realized automatically. Based on real-time topological analysis of hierarchical database, the topological problems of PSS/E simulation with full model are fixed, which ensures the validity of topological analysis. East China Power Grid model is used for practical application, and the simulation results verify the validity and practicality of this method. |
