摘要
传统电能质量自动补偿方法不能对电源并网行为进行可行性分析,且易导致配电指标失衡现象的出现。为解决上述问题,提出一种新型的电力配电系统电能质量自动补偿方法。通过分析配电自动化构成的方式,分析自动化配电原则、控制电力输入输出情况,完成电力配电系统的自动化装配。在此基础上,通过划分配电系统成分确定DEA补偿误差,并利用该结果完善补偿应用流程,完成新型自动补偿方法的搭建,实现电力配电系统电能质量自动补偿技术研究。设计对比实验结果表明,与传统技术手段相比,应用新型DEA电能质量自动补偿方法后,电源并网行为可行性提升35%左右,配电指标失衡情况得到有效抑制。
Traditional power quality automatic compensation methods can not analyze the feasibility of power Grid-connected behavior,and easily lead to unbalanced distribution indicators.In order to solve the above problems,a new automatic power quality compensation method for power distribution system is proposed.By analyzing the composition of distribution automation,analyzing the principle of automatic distribution,controlling the input and output of power,the automatic assembly of power distribution system is completed.On this basis,the DEA compensation error is determined by dividing the distribution system components,and the compensation application process is improved by using the results.The new automatic compensation method is built to realize the power quality automatic compensation technology of power distribution system.Compared with the traditional technology,the feasibility of grid-connected power supply is improved by about 35%and the unbalanced distribution index is effectively suppressed by using the new DEA power quality automatic compensation method.
