To enhance the stability of the data acquisition system of power grid dispatching system

a method of data acquisition with multi-machine and multi-link as the main control center is proposed based on the dispatching data network dual plane technology of State Grid Corporation and following the technology standard for data acquisition and exchange for smart grid technical support systems. The method uses the multi-line in load balancing

multi-machine in parallel running

multi-link in hot standby and multi-link data processing technology to improve the stability and reliability of data acquisition

solve the accuracy problem of the data caused by a single node failure to meet the needs of grid dispatching operation and control. The data acquisition system based on this method is in operation in several control centers.
