摘要：
In order to evaluate the impact of IBDG(Inverter-Based Distributed Generation) integration on the existing protections of distribution network and configure a proper protection scheme, a method of IBDG penetration level calculation considering the setting principle of 3-zone current protection for the distribution network is proposed. The operating status of IBDG is unceasingly assumed, verified and corrected until the verification result conforms to the assumption, the formula of short circuit current calculation is thus selected and the IBDG penetration level obtained, which meets the requirements of protection for both selectivity and sensitivity. The IBDG penetration level of a 10 kV distribution network is calculated and verified by simulation and the simulative results show the effectiveness of the proposed method. © 2016, Electric Power Automation Equipment Press.
