With the development of power networks

more timely and accurate information transmission for the dispatching automation systems is required. Compared with traditional telecontrol protocols

TASE.2 protocol is an ideal choice as a standard

complete and efficient protocol. The concrete situation of data exchange based on TASE.2 protocol

which is used in all the EMS/SCADA systems of Shanghai dispatching centers is introduced. The implementing schemes and the key technique are also described. The application results show the convenience and excellent reliability for the data exchange of the dispatching and production by the system proposed.
