关于简化城市电网网架的研究

RESEARCH ON SIMPLIFICATION OF URBAN NETWORE

本文对影响电网结构的两个主要问题──变压器负载率和电网接线方式提出了新观点。通过大量计算分析，证明在有些情况下，变压器采用低负载率是合适的，为简化电网接线创造厂必要条件，与“Ｔ”型等简化接线形式配合，能降低电网建设投资，提高电网的可靠性。

Two new viewpoints that influence thenetwork structure about loading of transformer andthat about tranformer connection are presented in thispaper. Through large amount of calculation and analy-sis it is proved that to adopt the low loading of trans-former is appropriate under certain conditions and thisixnecessary for simplifying network structure。 By useof lower transformer loading which matches the sim-plified structure the investment for nctwork construction can be decreased and the reliabllity of network canbe improved.
