摘要
对于众多供电企业来说,用户用电功率因数的高低,直接关系到电网中的电能损耗和功率损耗,关系到供电线路的电压波动和电压损失,而且关系到电能的节约和供电的质量。为此,如何提高配电网功率因数,已成为众多供电企业的一个重要课题。首先提出了电力系统中功率因数低对电网的所带来的影响及提高功率因数的意义,然后再给出了具体提高功率因数的方法,并在此基础上设定了一定参数进行了功率因数提高的仿真。从而从理论上解决了提高功率因数的基本办法,符合了众多供电企业功率因数的要求。
How to improve distribution network of the power factor,has become numerous of the power supply enterprise to an important issue.This paper firstly put forward the factor of power system to the power grid low the impact and the significance of improving power factor,and then presents a method of improving power factor,and on this basis set certain parameters for the power factor improvement simulation.Thus it solves the basic way to improve the power factor theoretically,the power supply enterprise with many power factor requirements.
