Fantastic House Diagram Of Synchronous Generator
Several generators can supply a bigger load.
House diagram of synchronous generator. The rotation of field poles in the presence of armature conductors induces an alternating voltage which results in electrical power generation. C as the phase. Such type of graphical representation that has a common vertical axis is known as house diagram.
I a is in phase with the terminal phase voltage v a. Individual generators may be removed from the power system for maintenance without shutting down the. Now let us derive expression for the excitation emf in each case.
Then the generator will. Suad ibrahim shahl 12 a if φ p is the flux per pole in the generator under no load then the generated voltage e a must lag φ p by 90 o b since the power factor is unity the phase current as shown in figure 2. 8 similar concept as applied in chapter 2 transformers.
You can see it in a given diagram. Obvious advantages of this arrangement are. Synchronous generators to supply power to the connected load.
A house diagram is constructed by taking the frequency power plots of two power supply systems and plotting them on the same diagram each with its own positive power axis. For a given phase voltage and armature current a larger internal voltage ea is needed for lagging loads than for leading loads. The phasor diagrams for a b lagging pf c unity pf and d leading pf.
Let us now start discussing the parallel operation with infinite bus more comprehensively i am starting with the basic idea of the house diagram. The phasor diagrams are as follows. Frequency power diagram of synchronous generator after paralleling.
