摘要
概述了光伏并网发电系统的基本原理及其出力特征。选用甘肃金昌电网作为研究对象,从负荷特性、电压、电网保护、电网规划、调度运行和调度自动化等方面分析了光伏并网对电网的影响,结合金昌电网自身安全稳定运行的情况,从技术可靠的角度对并网光伏发电系统提出相关技术要求,能有效确保金昌电网安全稳定运行。
This paper summarizes basic principle and output characteristic of grid-connected photovoltaic generation system. Gansu Jinchang power grid was selected as an example for analyzing affect on the power grid by photovoltaic generation in aspects of load characteristic,voltage,power grid protection,power grid planning,dispatching operation and dispatching automation. Combining self safe and stable operation of Jinchang power grid,relevant technical requirements for grid-con-nected photovoltaic generation system were proposed from the point of technical reliability which was of importance to en-sure safe and stable operation of Jinchang power grid.
