摘要
为解决微电网实验平台体积大、成本高等问题,设计和搭建了模块化、低成本、可编程的低压交流微电网实验平台。实验平台由分布式电源、线路和负载三部分构成,可以模拟分布式电源经传输线路向负荷点供电的微电网系统。详细介绍了分布式电源的硬件电路设计和软件构成。分布式电源可通过编程运行于恒压恒频模式或下垂控制模式,模块化设计可实现多个分布式电源组网运行,并降低实验平台成本。实际运行结果表明,该平台能够保障实验安全,加深学生对交流微电网及其运行模式的理解,并锻炼学生的实践能力。
In order to solve the problems of large size and high cost of the microgrid experiment platform,an experiment platform for the modular low-cost,programmable low-voltage AC microgrid is designed and built.The experimental platform consists of three parts: distributed generation, line and load, which simulates the microgrid system in which the distributed generation supplies power to load point through transmission line. The hardware circuit design and software structure of distributed generation are introduced in detail. The distributed generation can run in constant voltage constant frequency mode or droop control mode through programming. Modular design can realize the networking operation of multiple distributed generation and reduce the cost of experimental platform. The actual operation results show that the platform can ensure the safety of the experiment, deepen students’ understanding of AC microgrid and its operation mode, and exercise students’ practical ability.
