Parameter identification of synchronous condenser based on Grid Searching Method of Initial Values

摘要

The accuracy of the parameters of the synchronous condenser will impact on the stability analysis of the UHV DC system. This paper presents a joint identification strategy based on Grid Searching Method of Initial Values (GSIV) with multiple transient disturbances in power system. The identification results of this strategy satisfy the output curves of multiple disturbances at the same time. Therefore, the results have higher credibility. The simulation results show that compared with the traditional single disturbance identification strategy, this identification strategy has higher accuracy. The identification result is less affected by the initial value of the parameters and is more stable.
