[0055] The steps of the present invention are:
[0056] See attached figure 1 , The reactive power compensation method proposed by the present invention is suitable for the access area of the wind farm group, the specific implementation steps are as follows:
[0057] a. The voltage correction equation of the improved wind farm:
[0058] The Jacobian matrix of the system power flow contains the sensitivity information of the injected power of each node in the system to the voltage and phase angle. In the actual power system, not all nodes are connected to the electric field or load. Therefore, in order to reduce the number of observation nodes in the system, and to avoid the influence of the existence of nodes without power injection on stability analysis, some scholars proposed to divide the nodes in the network into “injected nodes” with power injection and those with no power injection. In the analysis process, the contact node is ignored, and the “injected node reduced-order Ja...
