摘　　要：介绍了一种电力系统电磁暂态仿真非线性元件算法。针对在电力系统电磁暂态领域广泛应用的EMTP(电磁暂态程序)和EMTDC(直流电磁暂态程序)技术存在一定的局限性,在此技术基础上提出了一种新的算法,并对非线性元件二极管进行算例证明。新算法为所有非线性元件提供了一种真非线性元件算法,解决了补偿法求解过程中遇到的假非线性元件精度低和拓扑约束的问题,即可求解任意拓扑结构的非线性网络。This paper presented a model of nonlinear elements for the simulation of electromagnetic transients in power systems.As the widely used packages available in power system electromagnetic transients EMTP（Electromagnetic Transient Program） and EMTDC（Electromagnetic Transient including DC） both have certain technical limitations,this paper put forward a new algorithm based on the EMTP,which provided a true-nonlinear solution to all nonlinear devices.It eliminated the less precise pseudo-nonlinear devices and all topological restrictions encountered in the compensation method used in the EMTP and EMTDC and could be applied to the arbitrary topological nonlinear network.
