介绍楚雄州新能源发展情况,楚雄北部电网与主网联系长距离联系,且110 kV 供电半径大,近区电网已有铁路牵引变等冲击性负荷,是楚雄州电网相对最为薄弱的环节。大量新能源接入后,需对新能源造成电网的潮流分布变化,无功电压变化,系统短路水平以及新能源与电网间的交互影响、电能质量方面的问题展开深入研究。
介紹楚雄州新能源髮展情況,楚雄北部電網與主網聯繫長距離聯繫,且110 kV 供電半徑大,近區電網已有鐵路牽引變等遲擊性負荷,是楚雄州電網相對最為薄弱的環節。大量新能源接入後,需對新能源造成電網的潮流分佈變化,無功電壓變化,繫統短路水平以及新能源與電網間的交互影響、電能質量方麵的問題展開深入研究。

Currently, large - scale grid - connected photovoltaic, wind power and other new energy are still in the initial stage. Chuxiong region has rich resources of wind energy, solar energy, and it is the rapid development area of new energy in Yun-nan province. North of chuxiong power grid is far apart from main grid, and 110 kV power supply radius is too far, and near region power grid has existed the impact of railway traction substation load, thus it is the weakest part of chuxiong power grid. After a num-ber of new energy access, the impact on power flow, reactive power and voltage, the system short circuit level, mutual influence, the quality of electric energy and so on is needed to be concerned.
