分布式发电对电网的影响及对策

Impacts of Distributed Generation on Power Network and Countermeasure

近年来,分布式发电(DG)作为一种经济、环保的发电技术在世界范围内快速发展,DG的接入将对电网带来多方面的严重影响,文章分析了DG的接入在配电网电压调节、继电保护及自动装置、供电可靠性、电能质量、电网规划及运行管理等方面造成的影响,并提出了消除负面影响的措施,对于电网经营企业应对DG的接入具有参考意义。

As an economical and clean power generation technology,distributed generation has been developing very fastly in recent years,power grid connection of DG has several kinds of serious impacts on electic power network,including impacts on voltage regulation 、 relay protection configuration、reliability of power-supply 、quality of electric energy、planning and operation of power network etc,in this article the author analyzes these impacts and presents some countermeasures to eliminate the negative influence exerted to public power supply system.it is useful for power network management enterprise to confront power grid connection of DG.
