在水电厂计算机监控系统中,顺序控制用流程图方式编程,是目前最为流行又易于被用户接受的控制组态方式。采用面向对象的方法开发的用流程图进行编程的顺序控制系统,提供了直观的、交互的方法来生成水电厂机组的顺序控制程序。在工程应用中,使用这种编程方法,实现机组的顺序控制显得十分方便。 In the computer monitoring system of hydropower plant, the sequence control is programmed by way of flowchart, which is the most popular and easy-to-be-accepted control configuration mode. A sequential control system programmed with a flowchart developed using an object-oriented approach provides an intuitive, interactive way to generate sequence control programs for hydropower plant units. In engineering applications, the use of this programming method to achieve the order of the unit is very convenient.
