计算机技术在水电厂的应用越来越广泛,在机组的自动化控制系统中的应用也日趋成熟,而机组辅助设备和公用设备自动化控制系统的复杂程度远不及机组自动化控制系统,以致利用计算机控制技术对辅助设备和公用设备进行控制没有得到相应的重视,所以,对水电厂辅助自动化控制进行研究是很有价值的。可编程控制器具有方便更新、扩展,维护工作量少及规模价格小的特点,故应用可编程控制器提高水电厂自动化水平很有必要,而且可行。介绍用特殊的计算机技术来完善这些部分的自动化水平。
The application of computer technology in hydropower plants is more and more widely, and the application in automatic control system of generating units is also becoming more and more mature. The complexity of automatic control system of auxiliary equipment and utility equipment is far less than automatic control system of generating units so that computer control technology Control of auxiliary equipment and utilities does not receive the corresponding attention, so the study of auxiliary automation control in hydropower plants is of great value. Programmable controller has the characteristics of convenient updating, expansion, less maintenance and small scale and small price. Therefore, it is necessary and feasible to apply programmable logic controller to improve the automation level of hydropower plant. Introduce the use of special computer technology to improve the automation of these parts.
