Which will be my reference frame while modelling and control - the reference machine in the network or the network bus itself?And if so how do i relate the dfig to this reference frame?
Thanks for your reply. But Instead of a single machine infinite bus,I needed to connect a dfig in a wind farm which already consists of synchronous generators and a few dfig's. So the synchronous machines will have a zero phase angle with the network bus but the dfig must have some phase difference with the bus due to the slip, isn't it? If yes, how do I find that angle via modeling?anorlunda said:By DFIG, do you mean doubly-fed induction generator, as in a wind generator?
Modeling can usually succeed with any choice of reference. However, choosing the network bus to be an infinite bus (voltage magnitude=100%, and phase angle=0), is both useful and often simplest.
A DFIG (Doubly Fed Induction Generator) is a type of electric generator used in wind turbines. It consists of a wound rotor connected to the grid and a stator connected to the generator control system. In a multi machine environment, multiple DFIGs can be connected together to form a larger power system.
To interface a DFIG in a multi machine environment, you will need to connect the stator and rotor terminals of each DFIG to the respective terminals of the other machines. This will allow for the exchange of power and control signals between the machines.
One of the main benefits of using a DFIG in a multi machine environment is its ability to operate in both grid-connected and isolated power systems. This allows for more flexibility in the power system and can help improve system stability and reliability.
Yes, there are some challenges to consider when interfacing a DFIG in a multi machine environment. One challenge is coordinating the control and protection systems of each DFIG to ensure proper operation and avoid any potential conflicts.
Yes, a DFIG can be used in a multi machine environment with other types of generators, such as synchronous generators or induction generators. However, proper coordination and control will be necessary to ensure efficient and reliable operation of the power system.
