【摘要】：从2003年美国提出智能电网开始,我国对电网建设投入了巨大的精力,并取得了显著的成绩。智能电网依靠数字技术和网络技术对电网进行严密的监测控制,为实现电网的信息化、互动化和自动化提供了技术支撑。智能电网用户侧建设将是电网发展的下一个重点。使电力用户能够实时了解自己的用电信息,并参与用电管理以降低本单位或家庭的用电费用,是实现科学用电、提高能效的重要手段。电网通过能效监测项目建设,引导用户用电负荷的转移,进行削峰填谷,降低对输配电设施容量的需求,能提高用户的收益,达到节能减排的目的。本文针对当前对能效监测的建设需求,设计了热工型和基本电量型两种监测终端。电力能效监测系统是能效采集系统的重要组成,主要用于发电厂、变电站、电力用户、电力通信中,为电力系统能效监测和控制提供有效数据支持。本文首先对能效监控进行了研究,分析了关键技术及能效终端的功能需求。主要对终端的硬件和软件进行了设计。首先给出了终端硬件框架、中央处理单元、输入输出单元、辅助单元和计量单元的硬件设计；然后分功能对软件进行分析,设计软件构架,针对构架设计了主线程、通信和采集模块软件的结构和功能,并对其他功能模块进行了单独设计。最后对能效终端进行了系统检测,保证了系统的安全性和可靠性。本文设计的监测终端提高了数据检测的智能化,促进监测终端质量提升,进一步为完善电力能效测评技术管理体系及推动需求响应服务提供了支撑。
[Abstract]:Since the smart grid was put forward by the United States in 2003, our country has invested a great deal of energy in the construction of power grid, and has made remarkable achievements. Smart grid relies on digital technology and network technology to monitor and control the power grid, which provides technical support for the realization of information, interaction and automation of power grid. Smart grid user-side construction will be the next focus of grid development. It is an important means to realize scientific power consumption and improve energy efficiency by enabling power users to know their own power information in real time and participate in the management of electricity to reduce the electricity cost of their own units or households. Through the construction of energy efficiency monitoring project, the grid can guide the transfer of electricity load, cut the peak and fill the valley, reduce the demand for the capacity of transmission and distribution facilities, increase the income of users and achieve the purpose of energy saving and emission reduction. According to the construction demand of energy efficiency monitoring at present, two kinds of monitoring terminals, thermal type and basic electricity type, are designed in this paper. Power energy efficiency monitoring system is an important component of energy efficiency acquisition system. It is mainly used in power plants, substations, power users and power communication to provide effective data support for power system energy efficiency monitoring and control. In this paper, energy efficiency monitoring and control are studied, and the key technologies and functional requirements of energy efficiency terminals are analyzed. The hardware and software of the terminal are designed. The hardware design of terminal hardware frame, central processing unit, input and output unit, auxiliary unit and metering unit is given. The structure and function of communication and acquisition module software are designed separately. Finally, the system detection of energy efficiency terminal is carried out to ensure the safety and reliability of the system. The monitoring terminal designed in this paper improves the intelligence of data detection, promotes the quality of monitoring terminal, and provides the support for perfecting the technical management system of power energy efficiency evaluation and promoting the demand response service.
