Electrical Power System is nervous system of any modern economy. The progress of any nation depends on the safe and stable operation of the system. For safe and stable operation of
Power System, it is important to understand the behaviour of the system under various operating condition’s beforehand. This can be understood by doing system simulations for various
operating conditions. For doing system simulation one have to build mathematical models or use of simulation software’s. This lab provides an opportunity for the students to build
mathematical models of the system components and analysing it with available simulation software’s like MATLAB or MiPower. In these lab students:
Models various types of system components like transmission lines, Generators, transformers, loads etc
Understands state of the system by doing Load flow analysis.
Studies various types of contingencies that arises in power systems like short circuit, voltage collapse, line outage etc
4. Plans how to optimize generation among different generating units etc
This lab is useful for the students for understanding various aspects of power systems operation and control.
Power system simulation software models the behaviour of electrical networks, from low voltage distribution networks (typically 110 and 240 V) to very high voltage grids
(up to 800 kV). They are mathematical models based on the electrical laws, offering a user interface specifically developed to represent networks equipment: substations,
transformers, overhead lines, underground cables, generators, including renewable energy sources like wind farms and photovoltaic panels, circuit breakers, SVC, etc. Power system
simulation models are a class of computer simulation programs that focus on the operation of electrical power systems. These computer programs are used in a wide range of planning
and operational situations including:
Long-term generation and transmission expansion planning
Short-term operational simulations
Market analysis (e.g. price forecasting)
These programs typically make use of mathematical optimization techniques such linear programming, quadratic programming, and mixed integer programming.
Key elements of power systems that are modeled include:
Load flow (power flow study)
Optimal dispatch of generating units (unit commitment)
Transmission (optimal power flow)
