| Abstract: | The governor oil pressure device is one of the most important electric auxiliary equipment at a hydropower station,and it is normally controlled by programmable logic controller (PLC) at small and medium-sized hydropower stations in the field of data acquisition. This paper discusses the control principles,major functions and the running mode of two typical kinds of PLC control manners widely used at present. The generator set LCU direct control mode is economical and adaptable to ordinary applications,and ... |
