The Need for Reactive Power Compensation
Hi I am little bit confused to compensate pf near unity or 0.97 at 132KV grid station on 11KV side. As fixed capacitors are connected in circuit, the pf becomes 0.94 capacitive and without connected capacitor pf is 0.93 lagging in normal or peak load condition. Total ...
Voltage control and reactive power management
Devices absorb reactive energy if they have lagging power factor (are inductor-like) and produce reactive energy if they have a leading power factor (are capacitor-like).. Electric grid equipment units typically either supply or consume the reactive power: [5] Synchronous generator will provide reactive power if overexcited and absorb it if underexcited, subject …
