城网自动化对110kV变电所设计的新要求

New requirement on design of 110 kV electrical substations for urban network automation

随着城网建设与改造的加快 ,城网配电自动化系统的实施建设 ,对 110kV变电所设计提出了新的要求。城市负荷增大、用地紧张、供电可靠性要求高等特点 ,使城网变电所设计面临诸多困难。本文从电源设置、主接线形式确定、设备选择和配电装置布置等方面提出了新的设计思路 ,指出了城网变电所小型室内化、无人值守综合自动化的发展方向 。

With the quickening development of urban network construction and upgradation, the introduction of urban network distribution automation system brings new requirements to design of 110 kV substation .The design task encounters such obstacles as urban load enlargement, building land insufficiency, higher electricity supply reliability, etc. The paper provides a new method of designing in terms of source allocation, busbar pattern determining, apparatus choosing and distribution device arrangement, etc. Further more, the paper points out that urban substations tend to be small sized, unattentive, comprehensively automatic.
