B. load flow and short-circuit
C. load flow and stability
D. load flow, short-circuit, and stability
Answer: D. load flow, short-circuit, and stability
Explanation:
AC Network Analyzer:
- AC network analyzer is a technique which used for solving the status of Load flow problems, Short circuit problems and Stability problems in electric power system.
- A network analyzer system was essentially a scale model of the electrical properties of a specific power system.
- Generators, transmission lines, and loads were represented by electrical symbols with representative values in proportion to the model of the system.
- Network analyzers did indirectly simulate the dynamic effects of the load.
- Instead, the analyzer would be used to solve dynamic problems in a stepwise fashion, first calculating a load flow, then adjusting the phase angle of the machine in response to its power flow, and re-calculating the power flow.
