摘要
以上海浦东配电网为对象,对配电线路电缆化对中压配电系统产生的影响进行了研究。从浦东配电线路电缆化的现状分析入手,对电缆线路与架空线路进行全面比较。阐述了电网接线方式、中性点接线方式、继电保护和配网自动化以及电网规划调度工作等方面,配电线路电缆化对中压配网的影响.并提出了相应的对策。
Taking the distribution network in Pudong district of Shanghai as objective, we analyze the influence caused by the changing of overhead power lines to underground cables in MV distribution system. The comprehensive comparison is conducted through analyzing the current situation after retrofitting in respects of power network connection mode, neutral point connection mode, relay protection, distribution network automation, power network planning and dispatching etc. The corresponding solutions are further suggested.
