摘要:

针对某变压器生产厂商的变压器油在注入、净油、储存等工艺进行研究,选用西门子S7-300PLC为核心控制器,运用Profibus-DP总线搭建了分布式I/O控制网络,以MCGS软件作为上位机开发软件设计了操作界面,对净油工艺进行改进并采用CMAC与PID并行控制策略对净油温度控制进行优化,提高了净油效率,能耗比原来降低近40%。使油品管理与使用实现自动化,很好的满足了变压器生产企业需求。

Abstract:

In studied of the transformer manufacturer on injection, net oil, the process of storage, Using the Siemens S7-300 PLC as the core controller and the Profibus-dp bus to build a distributed I/O control network, MCGS software development as the upper machine software design of the interface, improved the oil purification technology and uses the CMAC and PID parallel control strategy to optimizing the oil temperature control, efficiency improved of the oil purification, energy consumption nearly 50% lower than before. Make the management of the oil and use of automation, good meets the requirements of transformer manufacturers.
