Difference between voltage reactive power regulation and frequency active power regulation Frequency of whole system is the same. Frequency regulation is only in power plant,can only be realized by regulating the output of prime mover. Voltage level at different point in power network is different.Voltage regulation can be done dispersedly.There are various type of voltage regulation measures.Voltage regulation: hierarchical regulation and local balance In power network, reactive power consumption is much larger than active power. 电力拿镜广城洲量写控制四川省重点实验蜜 家电网电力系统广域测量与控制四川省重点实验室 Difference between voltage & reactive power regulation and frequency & active power regulation  Frequency of whole system is the same. Frequency regulation is only in power plant, can only be realized by regulating the output of prime mover.  Voltage level at different point in power network is different. Voltage regulation can be done dispersedly. There are various type of voltage regulation measures. Voltage regulation: hierarchical regulation and local balance  In power network, reactive power consumption is much larger than active power
