摘　　要：大规模电力系统的中长期电压失稳是一个缓慢的过程,其发生和变化与系统中慢速元件的动态行为紧密相关,研究电网中长期电压稳定问题需要选择能够反映其动态过程的仿真软件。选择PSS/E、PSD-FDS、Eurostag、PSASP和DSATools 5种仿真软件,通过仿真实验、程序参数、应用案例的对比分析,在原理算法、计算规模、元件模型、接口界面和实际应用等方面评估了各软件中长期时域仿真的特点、功能和适用范围,结果表明,PSD-FDS拥有更适合中国电力系统的模型库和数据格式,在实际系统中应用也更广泛,较其他软件更适用于中长期电压稳定研究。Mid-and-long term voltage collapse of large-scale power system is a slow process. The occurrence and changes are closely related to the dynamic behavior of slow components in system. Therefore, study on mid-and-long term voltage stabilities requires using simulation software that reflects slow dynamic process. Five simulation software packages, namely PSS/E, PSD-FDS, Eurostag, PSASP and DSATools are selected in this study. Practical analysis and evaluations are made to compare functions of these software packages in mid-and-long term time-domain simulations. Through simulation experiments, software parameters investigation and practical application examples, comparisons are performed on several aspects including principle and algorithm, simulation scale, components model and user interface. The results indicate that PSD-FDS provides better models and functions suitable for China power systems and precedes other software packages in mid-and-long term voltage stability research.
