摘要： 针对光伏发电并网系统中存在多种开关频率的电力电子器件,研究了一种基于显隐式混合积分的多速率仿真方法。利用电感和电容将光伏发电并网系统拆分为多个子系统,提出了一种多速率接口算法以使各子系统均满足实时性,给出了多速率仿真方法的稳定条件。在FPGA平台上搭建了数字式光伏发电并网系统,并进行了DC/DC和DC/AC变流控制器硬件在环试验,验证了上述多速率仿真方法的准确性。

Abstract: A multi-rate simulation method based on explicit-implicit hybrid integration algorithm for the grid-connected photovoltaic system which included power electronic devices with a variety of switching frequency was put forward. Inductances and capacitances were used to divide the grid-connected photovoltaic system into subsystems. A multi-rate interface was put forward to satisfy the request of real time. The stability criterion of the multi-rate simulation algorithm was put forward. FPGA was used as a platform to build the digital grid-connected photovoltaic system. The hardware in loop test for DC/DC and DC/AC converter controllers was conducted on this platform to verify the accuracy of the proposed multi-rate simulation method.

Key words: grid-connected photovoltaic system, real-time simulation, multi-rate simulation, explicit-implicit hybrid integration
