中文摘要：

基于机电暂态仿真的特性,对单级型光伏发电系统作了简化和假设。在PSASP软件环境下利用UD用户自定义模型,建立了单级型光伏发电系统机电暂态仿真模型。仿真对比了机电暂态与电磁暂态模型的动态特性,仿真结果证明了所建模型的合理性。

英文摘要：

Assumptions based on the characteristics of the electromechanical transient simulation, the single- stage type photovohaic power generation system were made. The simulation model of the single-stage type photovoltaic power generation system was developed under PSASP software environment. The simulation results show that the simulation model can reflect characteristics and functions of the single-stage photovohaic power generation system device accurately.
