鉴于大型抽水蓄能机组运行工况和工况转换多而复杂,涉及到机组同步并列的工况转换也较多,机组同步控制须考虑机组各种运行工况下的需求,同步控制回路设计既要提高回路可靠性,更要保证控制安全性,论述了大型抽水蓄能机组同步方式及同步点选择、控制回路设计原则,机组同步控制过程等内容,并给出一个典型抽水蓄能电站的同步控制设计。
In view of the large-scale pumped storage unit operating conditions and operating conditions change more and more complex, involving the parallel synchronization of the unit conversion is also more, unit synchronization control to be considered under various operating conditions of the unit requirements, synchronous control loop design both In order to improve the reliability of the loop, but also to ensure the safety of control, this paper discusses the synchronization methods and selection of synchronization points, the design principles of control loops and the synchronization control process of large pumped storage units. The synchronization of a typical pumped storage power plant Control design.
