双微机、PLC和PCC 3类调速器应用情况分析

Study on Application of Dual Microcomputer,PLC and PPC Governors

众所周知,在我国水轮机调速器的历史上,经历了机械液压调速器、模拟电液调速器、微机电液调速器的发展时期。现在水轮机调节器比较有代表性的3种是:双微机调节器,可编程(PLC)调节器,可编程计算机(PCC)调节器。从调节品质等方面对这3类调速器进行对比分析,可供参考。

As we all know, the domestic turbine governor history experienced mechanical hydraulic governor.analog electrical hydraulic governor and microcomputer electrical hydraulic governor times. And now, there are three types turbine governor which have representative characteristics： dual microcomputer governor, programmable （PLC） governor, programmable computer（PCC） governor, According to the adjusting Then the author shall make a rough comparison and analysis of these three type governors by his experiences of researching and manufacturing turbine governor for many years.
