介绍了电厂和变电站微机防误闭锁及顺序控制的工程应用背景,提出防误闭锁和顺序控制微机实现时规则库设计的类似之处。详细阐述了微机防误闭锁和顺序控制的设计要求及实现方式并重点介绍了两者规则库的设计方法。最后,对间隔层I/O测控装置防误闭锁及顺序控制规则库实现方法在工程应用中的效果做了简要说明。
This paper introduces the background of engineering application of microcomputer error-proofing and sequence control in power plants and substations, and presents the similarities of rule base design in the realization of error-proofing and sequence control. Described in detail the design requirements and implementation methods of anti-misoperation and sequence control of computer and emphatically introduced the design method of the two rule bases. Finally, a brief description of the effect of the method to realize the error-proofing of the I / O bay device and the implementation of the sequence control rule base in the engineering application is given.
