摘要
针对网架结构复杂的区域,提出利用双环网接线模式进行改造,同时分析了改造的必要性和高可靠性等优势。首先研究了双环网接线模式的结构和过渡方式。其次提出采用供电能力指标研究并初步分析常用10kV接线模式。之后建立考虑经济性和可靠性的综合评价模型,从负荷密度角度对比分析常用10kV接线模式,得到不同接线模式适用的负荷密度。最后,通过双环网接线模式在实际典型区域的应用和改造,证明其高可靠性和实用性。
For regions with complex network structure, this paper proposed transformation by use of the double-loop network connection mode, and analyzed its necessity and advantages including high reliability. Firstly, it discussed the structure and transition method of the double-loop network connection mode. Secondly, it proposed adoption of indicator for power supply capability, and made an initial analysis on the commonly used 10 kV connection mode. Furthermore, a comprehensive evaluation model considering economical efficiency and reliability was established for comparative analysis of the commonly used 10 kV connection mode in the respect of load density to obtain load densities suitable to different connection modes. Finally, actual application of the double-loop network connection mode in typical areas verified the high reliability and practicability of the proposed approach.
