To make the off-line electromagnetic simulation software, namely the real time digital simulator （RTDS）, enable to receive online power flow data of energy management system （EMS） and to send the real-time operation data of power system to RTDS to implement online simulation by RTDS and automatically tracking immediate state of power system, based on the RTDS model of South China power grid an online simulation system of EMS power flow data is developed. By means of performing online processing such as observability analysis, calculation of state estimation and detection and recognition of bad data and by use of DNP3.0 protocol of RTDS GNTET card, the estimation results, which is regarded as initial data for the simulation, are sent into RTDS to carry out the simulation, thus the ground state data of RTDS simulation is closer to actual operation state of power grid and the online simulation by RTDS is realized. The developed online simulation system is tested and verified by RTDS simulation model of Yunnan power grid, and the results show that the developed online simulation system is accurate.
