Embodiment Construction
[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.
[0028] 1. About the input and output parameters of this comprehensive optimization system
[0029] This comprehensive optimization system aims to make up for the defect that the original power system control and tuning system is only aimed at emergency control or reclosing and can not control actions uniformly, which leads to the excessive threat of secondary impact to the transient stability of the system in the case of permanent faults.
[0030] The system input parameters are divided into two parts: the offline calculation part and the online calculation part. The input parameters required for the offline calculation part are: system topology (nodes, line relationships, transformer distribution, line impedance admittance and other systems, line parameters), and short-circuit ...
