Embodiment Construction
[0047] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0048] This specific implementation mode discloses a site selection and capacity setting method for an inter-line power flow controller. The inter-line power flow controller is referred to as IPFC for short, such as figure 1 shown, including the following steps:
[0049] S1: Establish a static safety margin comprehensive evaluation index SC that can evaluate the target installation line of the power flow controller between the neutral lines of the power system sum ;
[0050] S2: Carry out N-1 fault scanning for all lines in the power system, and use the static safety margin comprehensive evaluation index SC obtained in step S1 sum Perform fault sequencing on all lines;
[0051] S3: Assign weights to each line according to the importance of all lines, and obtain the weighted safety index of each line under different faults;
[0052] S4: Select the...
