See formula (1). Kh= Inh-Ih Inh ÷×100%= 1- Ih Inh ÷×100% (1) In the formula. Ih --- After the filter works, the rms harmonic current content of the grid side is the root mean square value, the unit is Am (A); Before the Inh--filter works, the root mean square value of the hth harmonic current content of the harmonic source injected into the grid side is in Amperes (A). 3.3 Single-voltage harmonic compensation rate singleharmonic(component)compensationratioforvoltage For the series filter, the difference between the root mean square value of the hth harmonic voltage before and after compensation and the root mean square value of the hth harmonic voltage on the input side ......
