| Abstract: | There are a lot of advantages of the reserve generator controlled by the PLC,the reliability of the system and the ability of anti-jamming are improved by the PLC.It controls mainly by software,thus the development of the hardware is left out,and peripheral equipment is small.The functions of programming of the PLC are simple and feasible,so the demands of control system can be changed by the PLC.The external circuit of hardware needn't be changed,so the flexibility of system is improved. |
