一种用于静态稳定分析的故障参数化连续潮流模型

提出了一种用于电力系统静态稳定分析的新的故障参数化连续潮流模型和工具。在这一模型中，多个设备(包括注入型设备和支路型设备)的参数随着一个控制参数A的变化而同步变化。这一工具可以用来检查多重复杂故障对于大型电力系统的非线性影响，还可用来检验严重故障下系统静态潮流解的存在性。通过对国外一个3000节点实际系统的数值分析表明，所提出的模型和工具是十分有效的。

A NEW CONTINGENCY PARAMETERIZATION CONTINUATION POWER FLOW MODEL FOR STEADY STABILITY ANALYSIS

A new contingency parameterization continuation power flow model and tool for steady stability analysis is presented. The parameters of multiple equipments (the injection equipments such as generators and loads, and the branch equipments such as transformers and lines) are varied simultaneously with a control parameter in this model. This proposed tool is designed to investigate the nonlinear effects of enforcing a multiple compound contingency in a large-scale power system. In addition, this tool can be used to inspect the existence of a power flow solution under severe contingencies. Case studies with a practical 3 000-bus power system indicate that the proposed model and tool is very efficient.
