摘　　要：针对微电网与大电网能量交互的问题,设计了一种基于现场可编程门阵列(FPGA)实现的微电网并网控制器。该并网控制器以ADS7864芯片为核心实现数据的同步采样;同时,根据锁相原理,研究了一种改进的基于同步空间坐标变换的锁相控制算法,给出了锁相环模块中滤波器和PI调节器参数的设计方法。通过Matlab/Simulink仿真分析验证了锁相环的有效性,最后研制出基于FPGA实现的并网控制器并应用于微电网实验平台。实验表明该控制器能实现快速准确的数据采集和锁相控制,从而实现微电网的平滑并网。Aiming at the problem of energy interaction between microgrid and power-grid, a microgrid connection con- troller based on field programmable gate array（FPGA） is designed.ADS7864 chip as a key component is used in this controller to achieve the synchronous data sampling.And an improved phase-locked control algorithm based on syn- chronous coordinate transformation is researched.The design of relevant parameters of the filter in PLL module and PI regulator is given and the simulation is carried out based on Matlab/Simulink.And ultimately ,this controller on an microgrid experimental platform is done.Experimental results show this controller can achieve phase-locked control and data acquisition fast and accurately, so that grid-connected mode is implemented smoothly.
