摘要
针对电网三相功率不平衡造成的用户侧电压降低、电流不平衡度严重超标等问题,研究了适合于三相三线制系统和三相四线制系统的全电容无功补偿方式,通过Matlab仿真验证了理论的正确性,并探讨了补偿前、后的节能性。对装置进行了软、硬设计,通过试验验证了方法的可行性。
The random change of distribution network＇ s load, in particular a lot of unbalances in three-phase power on the peak period will cause serious situatioons such as the voltage reduction in users side , the excessive current unbalauce degree. This paper researched full-capacitance reactive power compensation mode suitable for both three-phase three-wire system or three-phase four-wire system, and verified the correctness of the theory by Matlab simulation test and discussed the energy-saving of the compensation. A reactive power compensation control device was developed by software and hardware design.
