Power Systems Engineering:
The Power Systems Engineering of the first decade of the twenty-first century has to face a variety of challenging tasks, which he can meet only by keeping abreast of the recent scientific advances and the latest techniques.
On the planning side, he or she has to make decisions on how much electricity to generate where, when, and by using what fuel. He has to be involved in construction tasks of great magnitude both in generation and transmission. He has to solve the problems of planning and coordinated operation of a vast and complex power network, so as to achieve a high degree of economy and reliability.
In a country like India, he has to additionally face the perennial problem of power shortages and to evolve strategies for energy conservation and load management.
For planning the operation, improvement and expansion of a power system, a Power Systems Engineering needs load flow studies, short circuit studies, and stability studies. He has to know the principles of economic load despatch and load frequency control.
All these above problems are dealt with basic concepts in the theory of transmission lines. The solutions to these problems and the enormous contribution made by digital computers to solve the planning and operational problems of power systems is also investigated.
