【摘要】：近年来,随着新能源发电的普及,越来越多的微网系统应运而生,微网是分布式发电设备和用户侧负荷的结合,为了确保其稳定运行,监控系统是核心部分,通过采集和监控各关键执行单元,及时反馈系统故障,对各单元进行协调调度,从而优化系统整体性能。而传统的微网监控系统缺少了可灵活配置性,主要是基于一套固定的模式去运行,可扩展性较差,而且设备协议多样化,很难接入监控系统统一管理。因此本文将研究重点放在区域微网监控系统未来的扩展,并且为了体现其灵活配置性,对区域进行场景划分;为了解决微网设备统一管理的问题,选择合适的统一通信协议。论文主要研究工作如下:(1)首先对区域微网监控系统的整体架构进行了深入分析,并基于区域微网监控系统的可扩展性对其软件功能进行了分析,最后结合实际的微网监控系统实验平台,对体现其可扩展性的软件功能进行了验证,这个微网监控系统也是本论文研究的雏形,本课题的研究成果也为该监控系统未来的拓展指明了方向。(2)基于三种典型区域微网场景——楼宇、校园、家庭,通过对各种有线、无线通信方式的研究和优缺点对比分析,并结合主站层统一通信接入的理念,研究合适的通信协议作为统一接入标准,分析后采用Modbus TCP协议。最后搭建其合适的通信网络拓扑,并使用Modbus Poll软件对搭建的通信网络拓扑进行实验测试,证实其通信的可行性。(3)在校园的中继实验中,为了解决其难以供电的问题,结合户外和太阳能的理念,对433MHz中继的供电模块进行制作,保证中继供电能力。(4)结合统一通信接入理念,由于Zigbee协议无法直接接入微网监控系统中,使用IAR软件将Zigbee网络无线采集的数据进行Modbus协议封装,实现区域微网监控系统对Zigbee网络的间接接入。
[Abstract]:In recent years, with the popularity of new energy generation, more and more microgrid systems emerge as the times require. Microgrid is the combination of distributed generation equipment and user side load. In order to ensure its stable operation, monitoring system is the core part.By collecting and monitoring the key execution units and feedback the system faults in time, the system can be coordinated and scheduled so as to optimize the overall performance of the system.But the traditional micro-network monitoring system is lack of flexible configuration, mainly based on a set of fixed mode to run, poor scalability, and equipment protocol diversification, it is difficult to access the monitoring system unified management.Therefore, this paper will focus on the future expansion of regional micronetwork monitoring system, and in order to reflect its flexible configuration, the scene division of the area; in order to solve the problem of unified management of micro-network equipment, select the appropriate unified communication protocol.The main research work of this paper is as follows: (1) firstly, the whole architecture of the regional micro-network monitoring system is deeply analyzed, and the software function is analyzed based on the expansibility of the regional micro-network monitoring system.Finally, combined with the actual microgrid monitoring system experimental platform, the software function which embodies its expansibility is verified. The microgrid monitoring system is also the embryonic form of this paper.The research results of this subject also point out the direction of the future development of the monitoring system.) based on three typical regional micronetwork scenes-building, campus, family, through the research of various wired, wireless communication methods and comparative analysis of advantages and disadvantages,Combined with the idea of unified communication access in main station layer, the suitable communication protocol is studied as the unified access standard, and the Modbus TCP protocol is adopted after analysis.Finally, the appropriate communication network topology is built, and the Modbus Poll software is used to test the communication network topology. It is proved that the communication is feasible in the campus relay experiment, in order to solve the problem that it is difficult to supply power.Combined with the concept of outdoor and solar energy, the power supply module of 433MHz relay is made to ensure the relay power supply ability. (4) combined with the unified communication access concept, the Zigbee protocol can not directly access the micro-network monitoring system.The wireless data collected from Zigbee network are encapsulated by Modbus protocol with IAR software, and the indirect access to Zigbee network is realized by regional micronetwork monitoring system.
