【摘要】：水能资源是清洁能源,可再生能源。合理开发利用水能资源,是我国经济社会可持续发展的重要支撑。在2011年中共中央国务院发布了关于加快水利发展的决定,要求加速开发水资源并积极地发展水电事业。本文以水电站为研究对象,介绍了水电站控制系统结构。论文根据电站的实际情况和参数,选用了竖井贯流式机组,调速器选用数字阀可编程智能调速器。结合水电站控制系统的特点,完成了水电机组PLC控制系统的设计和对机组控制系统硬件和软件的设计。该设计实现了机组开机控制、机组停机控制、事故停机以及紧急事故停机控制。对水轮机调速系统采用模糊PID控制算法,应用HG3000组态软件完成对水电站监控系统的设计。最后,评价了本电站在设计中不足,并对电站的发展进行了展望。目前电站已运行发电,实际运行结果表明,该系统能够满足实际应用的要求,并达到预期的目标。
[Abstract]:Hydropower resources are clean energy, renewable energy. Rational development and utilization of hydropower resources is an important support for sustainable economic and social development in China. In 2011, the State Council of the CPC Central Committee issued a decision on speeding up the development of water conservancy, calling for the accelerated development of water resources and the active development of hydropower projects. In this paper, the control system structure of hydropower station is introduced. According to the actual conditions and parameters of the power station, the shaft tubular flow unit and the digital valve programmable intelligent governor are selected in the paper. According to the characteristics of the control system of hydropower station, the design of PLC control system of hydropower unit and the design of hardware and software of unit control system are completed. This design realizes the control of unit startup, unit shutdown, accident shutdown and emergency shutdown. Fuzzy pid control algorithm and HG3000 configuration software are used to design the monitoring system of hydropower station. Finally, the shortcomings of the design of the power station are evaluated, and the development of the power station is prospected. The actual operation results show that the system can meet the requirements of practical application and achieve the expected goal.
