On the Effect Indicators of On-load Tap Changers of 500 kV Main Transformers and Related Control Strategy
摘要
Abstract
On-load tap changer of transformers is one of effective control methods to maintain the static voltage stability of power system.But the influences in lower grid by on-load tap changing of 500 kV main transformers could cause voltage instability of system.Through the study of the impact to the reactive power voltage and power flow distribution caused by tap changing,the effect indicators about voltage and reactive power can be presented to quantitatively measuring the changes of grid voltage and reactive power.The results show that,on-load tap changing of 500 kV main changers shouldn't be adopted separatly in the area with much distributed power,nevertheless it is considerable in the area with pure load or most connected power plants operating in constant reactive power.关键词
