当前,我国配电网,尤其是中压配电网的发展与输电网不相协调,亟需升级换代。目前,我国高压输电网得到较好的发展,管理水平和技术水平已经达到世界先进水平,然而,配电网尤其是中压配电网的管理水平和技术水平与发达国家之间相比存在相当大的差距,如可靠性指标、线损指标、电能指 At present, the distribution network in our country, especially the development of medium-voltage distribution network is incompatible with the transmission network, and it is in urgent need of upgrading. At present, China’s high-voltage transmission network has been better development, management and technical level has reached the advanced level in the world, however, distribution network, especially medium-voltage distribution network management level and technology level compared with developed countries there is Large gaps, such as reliability indicators, line loss indicators, electricity refers to
