Multi-mode DTS system union for regional power grid

A distributed computational model combination algorithm is presented for large-scale system union.The sub-net chooses the main-net for local computational model combination and power flow calculation and writes the calculated results back to the local devices.A multi-mode DTS(Dispatcher Training Simulator) system union is established according to the characteristics of regional power grid,which integrates the computational model combination mode with the boundary flow matching mode.Different union modes are selected during power system combination.The multi-mode DTS system union ensures the accuracy of combined network power flow and avoids large-scale combination calculation.It is adopted in Jiangsu provincial-regional associated anti-failure maneuver,showing satisfactory results.
