基于DIgSILENT和Matlab的微电网系统联合仿真
|
摘要
针对DIgSILENT在多节点运算时实时数据更新能力差的缺点,利用Matlab专业的数据处理能力,在单一使用DIgSILENT仿真模型的基础上加入Matlab仿真模块,代替DIgSILENT仿真模型中相对应的仿真插槽的内容。对比单一DIgSILENT仿真和联合仿真结果发现,在仿真速度不被拖慢的情况下,在微电网暂态调节时联合仿真较单一仿真调节到稳定状态时间上缩短了28.1%,系统电压超调量降低了13.3%,显示出联合仿真的优越性。
In this simulation experiment,in view of the disadvantage of poor real-time data updating of DIgSILENT in multi-node operation and the data processing capability of Matlab,a Matlab simulation module is added to the DIgSILENT simulation model to replace the corresponding simulation slots.The comparison of the results of the single DIgSILENT simulation and the joint simulation reveals that in the case of the unreduced simulation speed and the transient regulation of the microgrid,the time of adjustment to the stable state in the joint simulation is reduced by 28.1%,and that the system voltage overshoot is reduced by 13.3%,thus proving the superiority of joint simulation.
