DIgSILENT在电力系统稳定计算中的应用
|
摘要
因为电力系统仿真分析软件DIgSILENT(digital simulation and electrical network)引入时间较晚,可供学习和借鉴的资料不多,为了分析研究人员更加深入了解和应用该软件,介绍了DIgSILENT软件中电源、控制、接口、用户自定义模型等几个方面的特点;对该软件的同步发电机模型和负荷模型进行了详细的研究;并针对电力系统稳定问题,以单机无穷大系统为算例,应用DIgSILENT与Matlab进行联合仿真。结果表明:该方法不但没有牺牲计算速度和精度,同时还发挥了DIgSILENT在新能源发电机组建模精细化方面和Matlab在控制系统建模灵活性方面的优势。
Power system simulation software DIgSILENT(digital simulation and electrical network)was introduced for a short time,available information for study and learn was not too much.For more in-depth understanding and application of this software,the characteristics of the software in power supply,control,interface and user defined model,etc.were introduced and a detailed analysis of the synchronous generator model and load model on transient stability calculation in DIgSILENT were made.And in view of the stability of power system,a single machine infinite bus(SMIB)system was considered as an example,the combined simulation of Matlab and DIgSILENT was made.Results show that the combined simulation can not only guarantee the speed and precision of calculation,but also take the advantages of DIgSILENT in the modeling refinement of new energy generating units and also the advantage of Matlab in the control system modeling flexibility.
