font-size:

font-family: "Microsoft YaHei"; font-size: medium;">对测试数据进行分析可以得出以下结论:测量时系统电流为 698 A,三相电流相对平衡;负载在无电容柜运行时功率因数为 0.88;电流波形畸变非常明显,出现马鞍形,畸变严重;总电流畸变率在测试过程中最高达 14.1% ;3、5、7、9 次谐波都非常高,谐波相对基波比例分别为 11.0%6.6%,0.4%、4.8%。</p> <p style="margin: 0px 0px 1em; padding: 0px; list-style-type: none; box-sizing: border-box; font-family: "Microsoft YaHei"; font-size: medium;">此阶段谐波电流大小可根据公式 = lxTHD%,电流、畸变率以测量时计,谐波电流为98 A,考虑到谐波治理的必要性及负载的变化等因素,根据经验可知,治理容量需要相对放大余量进行,建议本段母线的可选治理容量为 100 A。同理,4*进线柜谐波电流为 117 A,建议本段母线的可选治理容量为 125 A;5*变压器电源进线柜谐波电流为 36 A,建议本段母线的可选治理容量为 75 A。</p> <p style="margin: 0px 0px 1em; padding: 0px; list-style-type: none; box-sizing: border-box; font-family: "Microsoft YaHei"; font-size: medium;">产生的问题因谐波引起,因此提出了针对电流谐波治理的建议方案:1变压器电源进线柜,安装 100 A 谐波保护柜;4"变压器电源进线柜,安装 125 A 谐波保护柜;5变压器电源进线柜,安装75 A谐波保护柜。谐波保护柜安装点如图4 所示。</p> <p style="margin: 0px 0px 1em; padding: 0px; list-style-type: none; box-sizing: border-box; font-family: "Microsoft YaHei"; font-size: medium;"><img

font-size: medium;">谐波产生的原因为非线性负载工作时,由于非线性负载输入端的整流电路阻抗不是一个定值,其阻抗随着外加电压的变化发生变化,导致整流器从电网吸取的电流不是正弦波电流。三相整流器也会产生谐波电流,但是这时对应每个波峰,不是一个脉冲电流,而是两个脉冲电流。无论单相整流器还是三相整流器,其电流波形都发生畸变,不再是正弦波电流,因此包含谐波成分。</p> <p
