Calculation and Restriction of Short-circuit Current in the Loop-closed Operation of Nansha Distribution Network
摘要
Abstract
The calculation and restriction of short-circuit current in the loop-closed operation of distribution metwork is studied in this paper, and then is applied in Nansha distribution network. First, the calculation model of short-circuit curren in the loop-closed opera-tion is presented. Then, taking into account the impact of short-circuit point and short-circuit form, a comprehensive calculating meth-od of short-circuit current is given, which can provide the biggest short-circuit current. Its short-circuit point and form can be maken clear as well. Secondly, the applicability of restriction measures of short-circuit current for the loop-closed operation of distribution network is analyzed one by one. Afterwards, the principle and implementation details are determined. The calculation of reactor pa-rameters is also presented. Finally, the proposed method is applied in the Nansha distribution metwork, the results show its feasibility and validity.关键词
