|
摘要
风力发电具有波动性的特点,因此为了避免风力发电并网对电网的冲击及其影响,将西门子S7-200系列的PLC控制系统应用在储能系统中来平抑风电功率的波动性。根据蓄电池和超级电容器组成的混合储能系统的控制要求,绘制PLC的硬件接线图;分析混合储能的控制过程,利用PLC的编程软件进行PLC编程;最后验证该控制策略的可行性。
Because of the fluctuation of wind power generation, in order to avoid the impact of grid integration on power grid and its influences, PLC control system of Siemens S7-200 series is applied to energy storage system to reduce the fluctuation of wind power. According to the control requirements of hybrid energy storage system composed of battery and ultracapacitor, the hardware wiring diagram of PLC is drawn. The control process of hybrid energy storage is analyzed, and PLC is programmed using PLC programming software. Finally, the feasibility of the proposed control strategy is verified.
