This paper present a Template Sparse Library for Power Systems (TSLPS) developed in C++. Its aim is to provide a coherent platform for many power system applications such as Load Flow(LF), Short Circuit(SC), Optimal Power Flow(OPF) and Transient

用于本科生电力系统稳态分析的潮流计算，本模板以三机九节点为例为例-It can be used as a template of powerflow.（steady-state analysis of power system）
