摘要
为解决传统220 kV/110 kV/10 kV降压模式在城市快速发展中遇到的诸多问题,深圳电网引入国际通用的20 kV配电电压等级,与当地实际情况相结合,试点采用220 kV直降20 kV供电模式,探索城市电网可优先选择的发展模式。叙述了深圳在光明新区试点应用500 kV/220 kV/20 kV/0.4 kV电压序列体系建构的思路、方法和应用实践,逐一阐述若干关键问题,为开展该项工作提出可供参考的意见和建议。
For solving many problems in rapid city development of traditional 220 kV/1 1 0 kV/1 0 kV voltage reduction mode,internationally used 20 kV power distribution voltage class was introduced in Shenzhen power grid. Combining with local practice,power supply mode of 220 kV dropping straight 20 kV was used for trial point and development mode for pri-ority selection for city power grid was explored. Idea,method and application practice of constructing 500 kV/220 kV/20 kV/0.4 kV voltage sequence system in Guangming new area in Shenzhen was described and several key problems were stated one by one which might provide reference opinions and suggestions for developing this work.
