Aiming at the problems existing in the application of remote control function in the " two coverage" work of metering automation in Guangxi power grid，three kinds of electric energy meters and two types of communication protocols for metering terminals commonly used in the field application of Guangxi power grid are firstly introduced． And then，from the aspects pf the compatibility of equipment communication protocols，the difference of " alarm before pull" control mechanism of Guangxi 97 protocol electric energy meter，and the security protection requirements of fee control system，the feasibility of remote control scheme for watt － hour meter by metering terminal is analyzed，and the recommended scheme and the switching － on process are given accordingly． The characteristics and difference of average response time between different communication modules and concentrator manufacturers are analyzed by testing． In addition，when commissioning the communication protocol of remote control function of the metering master station，the common abnormal problems found are analyzed with examples of upstream and downstream． It can provide experiences for the development of remote cost control function of metering automation system．
