please explain why: - in a power plant system, steam line from a power boiler (140 bar) is connected to one 100 MW turbine (1), and the other line is connected to 134 bar header to supply 100 MWe turbine (2) and to supply 82 bar header by using PRV for other turbines . question: when turbine...

please explain: - why increasing voltage from generator when power factor at lagging pf = 0.84, reduces PF to 0.82 and increases MVAR and kV from generator. 1. if the generator is leading which absorbs VAR? what to do to have PF to 1, and vice versa. 2. is this correct? power station charge...

what is the best for generator to have PF? in lagging or leading condition. - what is PF in capacitive and inductive, or lagging and leading. - we have one turbine is running on PF positive, and other is running on PF negative. why this system can work? -what makes generator to have PF...

good afternoon all.. can somebody explain why: - inceasing voltage of generator makes power factor decreases (lagging condition), MVAR decreases, and kV from generatot decreases. and vice versa. any idea would be appreciated... thank you

We want to calculate the Torque/Thrust required for opening/closing of the Damper/Gate. The data available with us 1. area of the damper/gate in Sq.mm 2. Opeating pressure in mm water col. (g) 3. operating temperature in Deg. C The damper is multi louver type used for reguating purpose and...

can somebody explain function of 150 kV protection for generator. situation: we have new steam turbine generator which is still under commissioning and it is parallel with other old turbines to 150 kV bus. the problem: we can not go to 50 MW due to 150 kV protection failure and raised...

okay, we have 7 steam turbines each 100 MWe. only one turbine runs with PF 0.93 while others is 0.82, why they dont like to increase the power factor? what are d possible reasons? - why increasing voltage generator, can increase power factor? - what is the best PF for 100 MWe generator, if you...

good morning, i am a new graduate working in cogen power plant. - i want to know, can i increase power factor to 1.0 from the steam turbine generator by increasing voltage from voltage regulator. - in our plant, power factor is 0.82 from generator.... if i increase voltage from voltage...

I am a new graduate working in a cogen power plant. I have question to share about water tube boiler (BFB and CFB type), "why filling up sand while running the primary air fan can be done for furnace floor which doest not have refractory. and if the furnace floor has refractory, the sand must...
