Embodiment Construction
[0016] The dynamic verification method of the external network equivalent model in the designated area in the power system proposed by the present invention, its flow chart is as follows figure 1 shown, including the following steps:
[0017] (1) Establish a regional extranet equivalent database, obtain the model data information of the current power system from the power system and store it in the regional extranet equivalent database. The model data information of the power system includes: power system topology, power The measured data of system equipment impedance parameters, power system branch power flow, power generation load flow and bus node voltage are used to perform state estimation calculation and power flow calculation on the power system model, and save the power system model section after calculation convergence in the regional extranet In the equivalent database; configure the border configuration of the designated area in the equivalent database of the region...
