摘要
分布式微电网中的设备具有分布广、数目多、协议互异、惯量小的特点,为了实现离网型微电网的稳定运行与有效监控,微电网能量管理系统(EMS)需要具备高速、可靠的信息通信系统以保障系统的协调运行。提出了一种基于“三层两网”的混合通信方式,同时采用多进程软件机制的通信网络架构,从硬件结构与软件框架两方面给出具体设计方案,并成功应用在一个海岛微电网的EMS中。实际应用验证了该通信系统的实时性和可靠性,为微电网提供了有效的信息保障。
Equipment in the distributed micro-grid are characterized as wide distribution, large number, different protocols, and small inertia. In order to make effective monitoring of off-grid micro-grid and achieve stable operation, the Energy Management System(EMS) needs a real-time and reliable communication network to ensure the coordinated operation of system. In this paper, a proven solution, which adopts hybrid communication infrastructure based on the "three-layer and two-network" concept and multi-process software framework is proposed. The specific network is given from hardware and software, and successfully applied to an EMS of an island micro-grid. The real-time and reliability of the communication network are verified by field operation, which can provide effective information for the micro-grid.
