高精度控制系统电磁暂态封装模型接口方法
Interface Method for Packaged Electromagnetic Transient Model of Control System with High Precision
摘要
Abstract
The complexity of electrical and control systems in power grid is increasing.With the rapid development of the renewable power generation technology,the accompanying packaged"blackbox"model brings challenges to the so-lution of control systems in electromagnetic transient(EMT)simulation.To solve this issue,a novel high-precision gen-eral interface method for the packaged EMT model is proposed.This general interface is adapted to the packaged"black-box"model based on the dynamic link library(DLL)technology,and the interface architecture is divided into three submodules,i.e.,InitMODEL,StepMODEL and TermMODEL.Especially,a novel improved Newton iterative method is designed for the solution of the packaged EMT model,and the general interface is adapted to the Newton iterative method,fixed-point iterative method and improved Newton iterative method.Finally,the interface method is verified by using packaged EMT models based on the DLL technology in three test cases,i.e.,a case of excitor and governor con-troller for a synchronous generator,a case of a grid-connected photovoltaic generator,as well a case of a grid-connected photovoltaic generator with a commercial"blackbox"model.Simulation results show the effectiveness of the proposed interface method for packaged models.关键词
