Nowadays, with the development of the EHV grid and area of megacity, such as Shanghai, Nanjing. There are many factories and AC-DC converter substations are involved into the urban region, which causes much more power quality problems than before, so that more and more people focused on the power supply using experience. In this article, we analyzed several evaluation methods of power quality used for now, then we make in-depth study about the characteristics in power supply for urban region and AC-DC EHV converter substations. And with the construction work of harmonic monitoring platform of State Grid, we can make a real-time judgment for power supply points, such as government, hospital, bank and so on. At last, we put forward a new power quality evaluation method for AC-DC converter substations. The method is based on the unique power quality parameters of power supply in city, it is established from four elements, which are: feature harmonic voltage, feature harmonic current , feature power and voltage change, all these elements constitute a method to evaluate the power quality of AC-DC EHV converter substations. And in the final result can be showed in a single symbol, which includes all the four elements.
