摘要:

基于甘肃河西地区多个区域性光伏电站并网工程设计及并网工作实践,提出了一种经济合理、可操作性好的打捆并网方案。通过电力系统分析综合程序(power system analysis software package,PSASP)仿真研究了该方案下各光伏电站的暂态特性、无功补偿配置、并网点注入谐波抑制等关键问题,形成了一套光伏电站打捆并网的新接入模式,对类似项目具有工程应用参考价值。

Abstract:

Based on the grid-connection engineering design and practice of several regional PV(photovoltaic) power plants in He-xi area of Gansu province, a bundled grid-connection scheme with good economy, reasonability and operability is presented. In this scheme, some important problems, such as transient characteristics, dynamic reactive power compensation configuration, harmonic analysis and suppression for grid connection point, are studied by PSASP(power system analysis software package) simulation, as a result that a new connected mode with several PV power plants bundled is formed, and its benefit to similar projects as references.
