摘　　要：DSP(dynamic simulation package)是南方电网科学研究院自主研发的电力系统计算分析软件,目前广泛应用于南方电网规划运行中。与国内常用软件BPA相互校核中,发现DSP与BPA的同步发电机模型的差异是导致两个软件暂态稳定计算结果不一致的重要原因。分析对比了DSP采用的基本形式同步发电机模型与BPA采用的标准形式同步发电机模型的差异,给出了两种发电机模型参数之间的转换关系,研究了DSP发电机饱和特性所采用的三段式饱和曲线和BPA采用的二次饱和曲线的差异并提出了拟合方法。在DSP中开发了标准形式同步发电机模型及二次饱和特性,并通过算例验证了该模型与BPA同步发电机模型的一致性。与BPA相比,DSP提供了基本形式和标准形式的两种同步发电机模型、三段式饱和及二次饱和两种饱和特性,可满足更加广泛的仿真模型需求。Dynamic simulation package(DSP)is a power system analysis software developed by Electric Power Research Institute of China Southern Power Grid Co.,Ltd.,which is widely used in the planning and operation of China Southern Power Grid.It is found that the difference between the synchronous generator models of DSP and BPA is an important reason for the inconsistent transient stability calculation results of the two software.In this paper,the differences between the basic form synchronous generator model of DSP and the standard form synchronous generator model of BPA are analyzed and compared,the conversion relationship between the parameters of the two generator models is given,and the difference between the three-stage saturation curve used in DSP generator model and the secondary saturation curve used in BPA model is studied and the fitting method is proposed.The standard form synchronous generator model and the secondary saturation characteristics are developed in DSP,and the consistency between the model and BPA synchronous generator model is verified by examples.Compared with BPA,DSP provides both basic and standard form synchronous generator models,and both three-stage saturation and secondary saturation characteristics,which can meet a wider range of simulation model requirements.
