when power angle=0, then the generator satisfies the load requirment(no power should be produced)
when power angle=90, then the generator satisfies doesn't the load requirment(extra power should be produced)
when power angle=above 90, then the generator is unstable and system collapse

Why must the oncoming generator on a power system be parralleled at a higher frequency than that of the running system?
If the frequency of the oncoming generator is slightly higher than the system frequency, the phase angle between the system and generator voltages will slowly change at a frequency equal to the difference between system and generator frequencies.
What is phase angle between line voltage and line current for resistive load in star connected system?
With a purely resistive load the phase angle will be zero. A 'star system' refers to a three phase power system with a resistive load placed between each phase and the neutral. If you have a resistive load(s*) evenly balanced across all three phases the phase angle will be zero, although depending on which point you look at, the current will actually be zero. The 'star system' is to help compensate for unbalanced loads. In practice you are going to have a lot of inherant inductance in such a system. So either the load will have some capacitance built into it to compensate or you will have a special reactive power compensator unit to deal with it. *Actually this will be three loads.

Why is power factor is cos of angle between voltage and current?
Power factor is the ratio of true power to apparent power -if you refer to the so-called 'power triangle', these correspond to the adjacent and hypotenuse of a right-angled triangle. The cosine of the angle between them is the ratio of hypotenuse (apparent power) to adjacent (true power). As the power triangle is derived from the voltage/current phasor diagram, this is exactly the same angle as that between load current and supply voltage.
What is meaning of apparent power in transformer?
Apparent power is the product of voltage and current in an a.c. system, and is expressed in volt amperes. The rated apparent power of a transformer is the product of its rated secondary current and rated secondary voltage.

How reverse power will occur during synchronizing?
Reverse power flow into a generator can occur during synchronization if the generator is spinning too slowly, or the voltage phase angle is lagging relative to the power system. If the generator is spinning too slowly, power from the system is used by the generator to increase its' speed. If the phase angle is lagging, an initial spike of power will flow into the generator to force it into sync with the system. Typically generator's will match system frequency very closesly, and force the phase angle to leading slightly between the generator and the system. When synchronized, an extra bump of power will flow out while the generator is torqued into phase with the system. This will avoid tripping any reverse power devices.
What is the meaning of the Malayalam word balaheenar?
Balaheenar = people poor in physical power.
What is the meaning of dcs at power plant?

What affect the phase angle?
Apparent power is the vector sum of a load's true power and its reactive power. If you draw a 'power diagram', the phase angle will be the angle between the true power and the apparent power. If true power is fixed, then increasing the phase angle will result in a greater value of apparent power.
What is power - physical power?
PHYSICAL POWER Physical Power is power obtain from the Universal power as we breathe in. it is used in all our activities: physically, mentally, emotionally, psychically, and spiritually
What significance has a power factor in an unbalanced system?
A three-phase 'unbalanced' system refers to the load, as the supply voltages are unaffected by load. So the phase-angle and, therefore, the power factor of each phase will be different -i.e. there will be three different power factors.
What is Relation between loss angle and Power factor?
Power factor = cos (angle)PF=cos @
How do you explain the meaning of the term federal system?
A system of government in which power is divided between a central authority and constituent political units
Why it is power fector of cos?

What does output watts per hour mean?
This has no physical meaning. The correct unit for power is the watt (not watt per hour).
