摘要
应用于大电网仿真的基于机电模型的PSD-BPA仿真软件无法准确描述电网内部环节动态响应过程,而应用于小电网仿真的电磁模型则存在计算耗时过长、不能用于整个电网等问题。以某工业园区为研究对象,利用基于电磁模型的PSModel软件搭建了工业园区各对象的数学模型,再使用基于机电模型的PSD-BPA软件搭建外部大电网模型,并在电磁模型与机电模型之间添加接口实现数据交换。仿真结果表明,机电-电磁模型混合算法既能获得大电网稳态数据,又能准确得到被研究区域的动态响应过程,可以准确模拟电网内电动机环节调速时的响应运行特性。
The PSD-BPA simulation software based on electromechanical model can not accurately describe the dynamic response process of power grid internal links,and the electromagnetic model applied to small power grid simulation has the problem of too long calculation time and can not be used for the whole power grid.Taking an industrial park as a research object,the mathematical model of objects in the industrial park is built by using the psmodel PSModel software based on electromagnetic model.After that,PSD-BPA software based on electromechanical model is used to build external large power grid model,and the interface between electromagnetic model and electromechanical model is added to realize data exchange.The simulation results show that the hybrid algorithm can not only obtain the steady-state data of the large power grid,but can also accurately obtain the dynamic response process of the studied area,and can accurately simulate the response operation characteristics of the motor link in the power grid when the speed is adjusted.
