摘要
随着光伏发电技术日益成熟,作为可再生能源越来越多的光伏发电设备作为本地电源为耗电量较大的工业园区提供电能。光伏发电受环境影响具有一定的随机性且光伏电源需经变流器并入电网,在发电的同时产生一定的谐波污染。光伏并网系统的控制方式以及并网系统的设备参数选择对光伏并网系统的技术参数有较大的影响,基于PSCAD仿真平台建立了光伏并网仿真模型,研究了光照及温度变化对光伏发电功率的影响,分析了LC并网滤波器的参数选择方法。最后,以100 kW工业园区光伏接入系统为例分析了不同并网模式的经济性。
With the photovoltaic technology matures,as a renewable energy more and more photovoltaic equipment as a local power as the power consumption of larger industrial park power photovoltaic power generation is influenced by the environment has a certain randomness and need to the converter power grid photovoltaic power supply,produce certain harmonic pollution in power at the same time Photovoltaic(pv)grid system control mode and the grid system of the technical parameters of equipment parameter selection of photovoltaic(pv)grid system has great influence,photovoltaic(pv)grid simulation model was built based on PSCAD simulation platform,the light and temperature change on the influence of photovoltaic power,analyzes the LC grid filter parameter selection method Finally,in 100 kW photovoltaic industrial park access system,for example analyzed different grid pattern of economy.
