Difference between voltage reactive power regulation and frequency active power regulation Active power source:only generator ->uniqueness Reactive power sources:generator, reactive power compensation devices (capacitor,reactor,phase modifier, static VAR)->diversity ■Active power source consumes primary energy, while reactive power source does not 电力拿镜广城洲量写控制四川省童点实验蜜 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  Active power source: only generator ->uniqueness  Reactive power sources: generator, reactive power compensation devices (capacitor, reactor, phase modifier, static VAR)->diversity  Active power source consumes primary energy, while reactive power source does not
