摘要
针对太阳能资源本身具有随机性、间歇性、周期性以及波动性的特点,当大容量光伏发电系统与电网并网时对系统交换功率的控制以及对配网和高压输电网的电压质量均有一定影响,为保证电网的安全稳定运行及提高供电质量光伏电站中应配置功率控制系统(AGC/AVC)。文中介绍了在光伏电站中应用的一种AGC/AVC控制系统的结构、控制模式、控制策略并给出了控制流程图,该系统已在宁夏多个光伏电站中成功应用,并取得良好效果。
High-capacity photovoltaic power generation system connected with grid has some influences on the control of system power exchange and voltage quality in high-voltage power transmission grid. For the safety and stability of power system and improving the quality of power supply, AGC/AVC should be allocated in photovoltaic power station. This paper introduces the structure, control method, control strategy and control flowchart of AGC/AVC in photovoltaic power station. The system has been successfully used in photovoltaic power stations in Ningxia Province and achieves good results.
