| Abstract: |
| An open design scheme is presented for medium and small hydropower plant automation system. Its system structure and software design are introduced. The PLCs (Programmable Logic Controller)of local control unit and the protection devices are connected directly with Ethernet. IEC60870-5-104 protocol and OPC (Ole for Process Control) are used in communication. Tech-nologies of OOP,multi-procedure,multi-thread and COM are used in the design of supervisory and control software. The identification of system data,the implementation of OPC server accessing and the application experiences of IEC60870-5-104 protocol are described in detail. The system runs reliably with better standardization and openness. |
