The present invention discloses a method for obtaining a model based on the RelayCAC relay protection setting software to realize the online verification function of the protection setting, which is to complete the automatic acquisition of the primary grid equipment and topology model required for the realization of the online verification function based on the impressive database model of the software. Creation, the creation of primary grid equipment calculation impedance parameters, the creation of primary grid graphics, the creation of secondary protection configuration and instantiated protection fixed value models, providing the support of original engineering data for the realization of subsequent online verification functions. These models include: the functional location model of the primary equipment grid; various types of calculation impedance and control parameter models of the primary equipment; the graphic model of the primary equipment support network construction architecture and real-time operation topology; the secondary equipment protection configuration template model and instantiated binding Define the protected equipment protection device and protection item model. The invention replaces the work of personnel analyzing the internal model and relationship of RelayCAC software and the maintenance work of manually creating the above-mentioned model objects.
Description
technical field [0001] The invention relates to an online verification of relay protection fixed value, in particular to a method for obtaining a model of an online verification function of a protection fixed value based on RelayCAC relay protection setting software. Background technique [0002] The reliable operation of power system relay protection has a huge impact on the safety and economic benefits of the power system. In order to improve the operation reliability of power system relay protection, power system enterprises have carried out online verification of protection fixed value operation. The so-called online protection fixed value verification is a kind of real-time reading of the telemetry and telesignaling data of the dispatching motion system as the basic data of the current power grid operation mode, to protect the horizontal time verification, the protection of the longitudinal timing coordination verification, and the protection sensitivity calibration Var...
