1.MVA or armature current limit of generator: this depends on the cooling system of generator so that temperature rise in generator is limited to safe value.depending on cooling system effectiveness and temperature limit for the insulation used in generator, MVA limit is decided.
2.MW limit: this is determined by the power output capacity of prime mover to which generator is connected.
3.rotor angle limit: this is related to stability of generator which is synchronised to the grid.ideally this could be 90 degree, but in practice this is limited to70 degree so as to have better stability margin in transient and dynamic condition.the generator falls out of synchronism in trasient condition if rotor angle is close to 90 degree.
4. rotor current limit: the field winding placed on rotor has got limited current carrying capacity, beyond which it may burn .so this limit is used.
all these limitters make capability curve of g generator within which the generators operates safely

What is the use of define key word in c?
Actually, the preprocessor is not part of the C compiler, but here you are: #define is meant to define symbols. Examples #define NULL ((void *)0) #define getchar() getc(stdin)
Write a assembly languagprogram that generates and displays 50 random integers between -20 and plus 20?
There are a few different ways to do this but this one will work just fine for your problem. (note these numbers are not truly random, but they will probably be random enough for your purposes) you will have to: import java.util.Random; then define a new random number generator called Generator: Random generator = new Random(); Then, make a random integer between 0 and 40 and subtract 20 so it is between -20 and positive 20. int myNumber = generator.nextInt(40) - 20;

Define generator short circuit ratio?
Checked Stephen J. Chapman's Electric Machinery Fundamentals page 287. It says: Short Circuit Ratio (SCR) for the synchronous generator is the ratio of the field current required for the rated voltage at OPEN circuit to the field current require for the rated armature current at SHORT circuit.

No. A loan utilizes one's credit, but the loan does not define one's credit capability.

How do you determine transfer function of a synchronous generator?
This is just one of the ways:Choose the variables couple in question defining the SISO form of the system. Write out the state space matrix commonly denoted as "A" of the synchronous machine. Calculate the eigenvalues of that matrix. Then calculate the residues of the matrix with respect to the selected SISO system (the chosen variables in question define the input matrix B and output matrix C). The eigenvalues are the zeros of the transfer function while the residues are the constants in the fractionally partitioned form of the transfer function.The matrices I was talking about define the linearised system in the form :dx/dt=Ax+Buy=CxFor a more thorough explanation seePower System Stability And Control By Prabha Kundur

What do support relationships define when one capability supports anothere?
Support relationships define the interdependencies between different capabilities within a system, illustrating how one capability enhances or facilitates the performance of another. This interaction often highlights the importance of collaboration and resource sharing, where the supporting capability provides necessary tools, information, or expertise. Understanding these relationships is crucial for optimizing performance and achieving strategic objectives within organizations or processes.
What are capability classes?
Capability classes refer to categorizations used to define and manage the abilities or skills that individuals or organizations possess. These classes can help in assessing competencies, identifying training needs, and aligning resources effectively. In various fields, such as education and workforce development, capability classes facilitate targeted development strategies to enhance performance and productivity.
Define the term critical field resistance?
critical resistance is the maximum resistance beyond which the generator failed to exite. it can b found form the occ of the generator.
Define Global Software Development?
Global Software Development (GSD) is "software work undertaken at geographically separated locations across national boundaries in a coordinated fashion involving real time (synchronous) and asynchronous interaction".
