传统的高、低压厂用电的自投逻辑是由继电器来实现的,在进行DCS改造后,则是将自投逻辑所必需的外部条件送入DCS,由DCS进行逻辑判断,实现工作电源的低电压保护跳闸、备用电源的自投合闸和合于故障后的加速跳闸等功能。由DCS实现的自投逻辑与原来由继电器实现的自投逻辑在功能上是一样的。这里值得指出的是在高、低压厂用电的自投逻辑中,工作电源的欠压(低电压保护)、失压、备用电源的有压判断,有的电厂是由继电器来完成的。在继电器达到整定值后动作,其接点作为DCS的逻辑条件送入DCS。而我厂则是利用工作母线和备用母线的电压变送器,进行工作电源的欠压、失压、备用电源的有压判断,定值大小由DCS内部整定。在进行DCS改造后,为实现数据的显示和数据采集必需将工作母线和备用母线电压送入DCS,因此,不需再另加电压继电器进行自投逻辑判断。
