摘要
采用精确模型模拟电力系统设备动态行为是获得可信仿真结果的前提。虽然电力系统仿真软件提供了标准模型库,但随着电力技术的进步和新型控制装置的投入,原有的模型库无法完全满足数字仿真的需要,因此有必要开发仿真软件的用户自定义模型。本文介绍了PSS/E用户自定义建模原理,归纳了自定义建模详细流程,并结合实际项目,建立了福建水口电厂发电机组励磁系统的自定义模型,采用PSS/E的模型检测功能进行校核,结果表明该模型的正确性和实用性。本文研究的PSS/E自定义建模方法同样适用于电力系统其他设备的自定义建模。
Accurate and sufficient detailed power system elements models are essential to the precise calculations of the power system stability limits. Although standard model libraries which include widely used models are developed by large power system software packages, they couldn＇t simulate some special equipments and control facilities. In the paper, PSS/E User-Defined Modeling （UDM） Technique is introduced. Dynamic simulation models which are not included in the library could be defined by using the UDM technique. The detailed flow chart of UDM is also described. The technique has been successfully used for excitation system modeling and parameter identification in Fujian Power Corporation of China. The simulation results and field testing given in the paper show that the user-defined model is accurate and sufficient detailed compared with the real excitation system. The UDM method proposed in the paper is also applicable for the modeling of other power system elements.
