孤岛式风光柴蓄智能微网系统的研制

Research on Islanded Wind-solar-Diesel-Battery Intelligent Micro-Grid System

为解决海岛地区用电难问题,基于微网技术,利用太阳能、风能、柴油机、蓄电池等研制开发出一套智能微电网系统。以单片机为核心进行了系统方案设计和硬件电路设计,并基于能量调度策略设计了系统运行控制程序。样机系统集成并进行了负载投切试验、稳定性试验和超负荷试验,现已投入试运行。结果表明,该微电网系统工作状况良好,整体性能稳定可靠,智能控制功能满足实际要求。

An intelligent micro-grid system based on the micro-grid technology is developed to supply electricity for an island using solar and wind power, diesel generators and batteries. The system is designed with a microeontroller as its core. This paper presents the scheme design, circuit hardware design and operational control procedures of the system based on the scheduling strategy of energy. A prototype of the system is integrated and the load, stability and overload tests are carried out accordingly. The experiment suggests that the micro-grid system designed can work in good order with stable and reliable performance, and it can meet the actual requirements.
