The gas electricity generation is not only alleviating the present energy tight situation in our country, but also is one of the most effective ways to comprehensible use gas resources. A remote monitoring system for gas-combustion generator units based on Power Builder is presented in this information of paper. The system can remote control units start-up or shut-down, can remote measure automatic incorporated generator, auto-disconnection and power allocation. The system record various parameters and information of generator units real time, it realizes remote monitor the all operating parameters and running condition.
