【摘要】：开发利用新能源是解决全球面临的能源短缺问题和环境污染问题的有效途径。在众多形式的新能源当中,风能和太阳能以其资源丰富,获取简单,利用过程无污染等特点成为了重点研究对象。利用风能和太阳能发电可以对这两种新能源进行有效利用,通过发电系统,把风能或太阳能转换成电能,从而进行能量的存储和分配,使得能源得到更有效的利用。风、光发电最大的缺点就是能量转化率低,发电效率低,解决发电效率低的问题是新能源发电的重点研究对象。本文分别对风力发电和光伏发电的原理进行了简要说明,根据光伏电池、风力发电机的输出特性,研究其功率控制策略,通过对比选择最佳的最大功率点跟踪(MPPT)算法,并对算法进行分析改进。根据选择的算法和实际发电需求,分别设计了光伏发电、风力发电MPPT控制器。控制器能够有效地完成最大功率点跟踪,提升光伏电池或风力发电机的输出功率,并且实现了发电情况显示,与其他设备通信,蓄电池保护等功能。通过此控制器可以很容易地实现发电系统和监控系统的搭建。通过控制器、逆变器和其他设备共同组建成风光互补发电系统,风光互补发电可以削弱环境因素对发电的影响,通过发电系统可以实现电能存储,并网。本文选择了某个居民社区,对该社区进行风光互补发电系统的设计,发电系统发出的电能不仅能满足居民需求,还能向外部电网输送电能。本文在发电系统的基础上设计了监控系统以保障发电过程的稳定。监控系统包括了系统的通信、上位机监控和远程监控。采用有线和无线结合的方式保障通信流畅;通过上位机就可以实时显示,对故障进行监控和查询,监控系统还可以通过yeelink实现数据上传到互联网,实现数据的网络查询。
[Abstract]:The development and utilization of new energy is an effective way to solve the problem of energy shortage and environmental pollution faced by the world. Among the many forms of new energy, wind and solar are rich in resources and easy to obtain. The use of the process without pollution has become a key research object. The use of wind and solar power can be used to effectively use these two new energy, through the power generation system, wind or solar energy can be converted into electric energy. So that energy can be stored and distributed so that energy can be used more efficiently. The biggest drawback of wind and light power generation is low energy conversion and low power generation efficiency. In this paper, the principles of wind power generation and photovoltaic generation are briefly explained. According to the output characteristics of photovoltaic cells and wind turbines, the power control strategy is studied. By comparing and improving the best MPPTs algorithm, the photovoltaic power generation is designed according to the selected algorithm and the actual power generation demand. MPPT controller for wind power generation. The controller can effectively complete the maximum power point tracking, enhance the output power of photovoltaic cells or wind turbines, and achieve power generation display, communication with other equipment, Battery protection and other functions. Through this controller can easily achieve the generation system and monitoring system construction. Through the controller, inverter and other equipment to form a wind complementary power generation system, Wind and wind complementary power generation can weaken the impact of environmental factors on power generation, through the power generation system can realize the storage of electricity, connected to the grid. This paper selected a resident community to design the wind complementary power generation system. The electricity generated by the power generation system can not only meet the needs of the residents, but also can transmit electricity to the external power grid. This paper designs a monitoring system on the basis of the generation system to ensure the stability of the generation process. The monitoring system includes the communication of the system. The host computer monitoring and remote monitoring. Using the combination of wire and wireless to ensure the smooth communication, through the host computer can display in real time, monitoring and querying the fault, monitoring system can also through yeelink data upload to the Internet, Realize the network query of data.
