| Abstract: | Frequency stability will become the main security risk of Yunnan Power Grid as multi.DC sending end with small load and large sending power after the asynchronous interconnection with CSG. The influences of load model and governor parameters on frequency characteristics are investgated. The principle of coordination and optimization of over requency generator tripping are proposed. Based on the simulation and analysis of 4 alternative schemes, the over frequency generator tripping scheme is proposed for Yunnan Power Grid to meet the requirements of asynchronous interconnection |
