调整不平衡电流并补偿功率因数的新型节能设备

New energy-saving equipments for adjusting unbalanced currents and compensating power factor

本文介绍的这种新型节能设备能够把配电网三相不平衡电流调整到平衡状态的同时,把三相的功率因数都补偿到“1”。其主要方法是根据电路中已有的阻抗量借助智能化的管理与计算将适当的电容量加到三相电路中,从而达到既提高电路的功率因数又平衡电路中的三相电流。文章以实例阐述了基本原理。仿真实验和挂网运行实践的真实数据对其工作原理的科学性、节能效果(功能)的确定性以及性能指标的可靠性提供了有力的肯定性证实。该新型节能设备目前已经应用于辽宁省的沈阳、大连、大石桥、康平等城乡结合部电网和农村电网中并显现出良好的节能效果和可靠的性能质量。

This paper introduces such new type of energy-saving equipments as to compensate the power factor to unity, and adjust unbalanced currents to balance condition at the same time. The main method of which is to add appropriate capacitance to the three-phase circuit according to the existed quantity of impedance in the circuit and with the aid of intellectual management and calculation, thereby bo achieve the goal of not only improving the power factor but also balancing the three phase currents of the circuit The paper sets forth the basic principle with examples. The real data obtained from simulation experiment and practical operation on network offers powerful positive confirmation on the scientific nature of its working principles, affirmation of energy-saving effect and reliability of perfomance index At present these new type of energy-saving equipments have been used in town and rural power network in Shengyang, Dalian, Dashiqiao, Kangping etc. area of Liaoning province, and displays good energy-saving effect and reliable performance quality.
